Do you have a woodburner or log burning stove and need to stock up for the winter?

Tip – best to buy by volume but if buying by weight then make sure the wood is seasoned.

It is better to buy wood by volume than by weight because between 35% and 60% of the weight of freshly felled wood comes from water. Under the Weights and Measures Act, coal and smokeless fuel have to be sold in defined weights, which makes it easy for you to compare the cost between suppliers. Unless there is a local statutory instrument in force, there will be no such statutory weight for deliveries of wood. The logs and wood are usually sold in “nets” or by lorry load, so take care to check the amount you can expect to get for your money. Fresh felled wood weighs about one tonne per solid cubic metre but will lose up to half its weight when it becomes fully air dried, so find out for how long the wood has been seasoned before delivery.

Tip – make sure the logs are the right size for your stove

Ideally, logs purchased should be no more than 10cm thick. Any that are will need to be split again to ensure that they burn properly. Generally speaking, close grained smooth woods make better fuel than those in which the grain is open and rough.

 Poplar is one of the wettest woods when freshly fuelled and ash (at 35%) one of driest. Seasoning reduces the moisture content of the wood. Wood felled during one winter should be seasoned until the next and preferably a second winter before it is burned. Trees felled during the Spring/Summer will have a very high moisture content compared to those felled in late Autumn/Winter, therefore whilst a log first cut in January may be ready to burn within say, a year, it is necessary for a log cut in May to be seasoned for at least two years.

 

When buying firewood – what is a chord?

The chord is one of the most common measurements for purchasing fuel wood.

A cord is a stacked unit volume of wood measuring

4 x 4 x 8 feet    = 128 cubic feet This volume includes bark and air space. Due to the irregular shape of wood the air space in the cord can be as high as 40 percent. The net cord volume can therefore be as low as 75 cubic feet. In general net cord volume range 80 – 100 cubic feet.

1ft(foot) = 0.3048m

Using wet or fresh wood for a fire

In simple terms, the word ‘seasoned’ means ‘dry’ and the term ‘green’ means ‘freshly cut from living tree’.

Why is it not a good idea to burn green wood on a fire?

Green wood carries about a third of its weight as water, which on the fire evaporates and helps to carry the heat away up the chimney.  You can often hear a log sizzle or hiss in the fire if it is too green or damp.  

How do I know if wood has been seasoned?

It’s essential to know that the wood you are buying is properly seasoned and not still full of moisture. Here are some quick checks to help you tell the difference:

  • Seasoned wood weighs much less than green wood.
  • Seasoned wood looks darker, or grey when compared to freshly cut or “green” wood which is usually more yellow or cream coloured.
  •  Seasoned wood will have drying cracks showing at the flat, cut end.
  • Seasoned wood will have loose bark compared to the bark of green wood which will be tightly attached.
  • When two pieces of seasoned wood are knocked together they make a high, hollow sound whereas green wood makes a more dull sound.
  • Seasoned wood should not hiss when burnt, this is the water in the wood boiling and being forced out as steam. 

What to do if you buy wood that has not been seasoned

If you buy logs which have not been seasoned, you should cut them to length (300mm or 10″ to 18″), split to size and stacked. Tree branches and trunks contain thousands of microscopic tubes which carry water from the roots to the leaves, and these tubes can stay full of water for years after the tree has been felled (or pruned). Cutting the wood to shorter lengths opens these tubes to the atmosphere which increases evaporation.

The stack should be completely covered on the top to prevent rain wetting the wood but air must be allowed to reach the sides of the stack. Leave to season for at least 1 year (more if possible). Some logs may take 3 to 4 years to fully season. Bring the fuel into the house a few days before you want to use it to get it as dry as possible. 

All wood will, when supported by lots of kindling and/or a good ember base, will burn unseasoned. However, you may find some woods are not worth using in this state due to the length of ‘hissing’ time (as the water boils from within the wood) before they can burn.

Moisture content of firewood

  • by volume wet wood has about 85% of the energy of oven-dry wood
  • by weight wet wood has less than half –  42% – of the energy of oven-dry wood
Whilst seasoning it should preferably be stored under cover in an airy place such as an open sided lean-to. The only way of knowing if your firewood is ready to burn is by knowing the moisture content. Wood should be burned when the moisture content is below 25% – ‘air-dry’. You can tell if a log is dry because the bark will come away easily in the hand and the log will have splits across the grain.  
 
You can also purchase a damp or moisture meter from any hardware store that is suitable for use on wood.   If you buy your own moisture meter you will be sure that your logs are dry enough to burn. Owning a moisture meter will also reduce any ‘misunderstandings’ on the suitability of the logs you buy in: pick a random log, split it and use the moisture meter to measure the moisture content of the wood across the grain.
 
It is important the logs are dry and well seasoned. Burning wet or unseasoned wood is less efficient and can cause harmful build up of deposits in the chimney over a very short time. Thick coatings of creosote or resinous material can cause chimney fires, or prevent the chimney functioning properly. This can allow harmful fumes to escape into the dwelling.

Difference between hard and soft wood

The two categories of woods, softwood and hardwood, do not actually refer to how hard or soft a wood is to the touch but rather how dense the wood is.  Hardwoods are trees that lose their leaves seasonally, and softwoods are trees that keep their foliage all year.

Typical Firewoods

Ash, white – Hardwood – Good firewood

Beech – Hardwood – Good firewood

Birch, yellow – Hardwood – Good firewood

Chestnut – Hardwood – Excessive sparking, can be dangerous

Cottonwood – Hardwood – Good firewood

Elm, white – Hardwood – Difficult to split, burns well

Hickory – Hardwood – Slow steady fire, best firewood

Maple, sugar – Hardwood – Good firewood

Oak, red – Hardwood – Slow steady fire

Oak, white – Hardwood – Slow steady fire

Pine, yellow – Softwood – Quick hot fire, smokier than hardwood

Pine, white – Softwood – Quick hot fire, smokier than hardwood

Walnut, black – Hardwood – Good firewood

burning logs in fire

Firewood 

“To have no fire, or a bad fire, to sit by, is a most dismal thing.”

William Cobbett

Lighting a fire

They say that making up a fire is an art in itself and everyone finds what works for them eventually – I was always told that a fire should light with one match and generally I have found that to be so.  Having got the fire to light sometimes it just doesn’t do and I am at a loss as to why.  For an explanation and tips on how to light a fire check out this article.  

Below is a poem by an unknown author that may help us all to know the best firewood to burn and keep us warm.

What to burn

“Oak logs will warm you well, if they’re old and dry.

Larch logs of pine will smell, but the sparks will fly.

Beech logs for Christmas time; yewl logs heat well.

‘Scotch’ logs it is a crime for anyone to sell.

Birch logs will burn too fast; chestnut scarce at all.

Hawthorn logs are good to last, if you cut them in the fall.

Holly logs will burn like wax; you should burn them green.

Elm logs like smouldering flax, no flame to be seen.

Pear logs and apple logs, they will scent your room.

Cherry logs across the dogs smell like flowers in bloom.

But ash logs, all smooth and grey, burn them green or old.

Buy up all that come your way, they’re worth their weight in gold.”

The quality of firewood is based upon various characteristics such as its speed of burn, heat given off, tendency to spark (spit), ease of splitting, time required to season, etc.

 Grade: 1 = Poor, Grade: 2 = Okay, Grade: 3 = Good, Grade: 4 = Excellent.

Firewood Rating Table
Common Name:  Botanical Name:  Comments:
 Alder Alnus  Low quality firewood.Grade: 1 
 Apple Malus  Needs to be well seasoned. Burns well with a pleasant smell and no sparking/spitting. Grade: 3
 Ash Fraxinus  One of the best firewoods. It has a low water content and is easily split with an axe. Burns best when seasoned but can be burned green. Grade: 4 
 Beech Fagus  Beech has a high water content and will therefore only burn when seasoned. Grade: 3 
 Birch Betula  An excellent firewood that will burn when green. However, it burns quickly so should be mixed with a slower burning wood such as Oak. Grade: 3/4
 Cedar  Cedrus  A good firewood which burns with a pleasant smell. Gives a good lasting heat and does not spit much. Small pieces may be burned green.Grade: 2/3 
 Cherry Prunus  Must be well seasoned. Burns with a pleasant smell without spitting.Grade: 2/3 
 Elm Ulmus  A good firewood but due to its high water content of approximately 140% (more water than wood!) it must be seasoned very well. It may need assistance from another faster burning wood such as Birch to keep it burning well. However it gives off a good, lasting heat and burns very slowly. Larger pieces of wood will prove difficult to split. Grade: 2/3
 Eucalyptus Eucalyptus  Allow to season well since the wood is very sappy when fresh. Can be difficult to split due to stringy wood fibre. Best method is to slice into rings and allow to season during the summer, the rings will start to split themselves. Burns fast with a pleasant smell and without spitting. Grade: 2/3
 Hawthorn Crataegus  A good firewood. Grade: 3/4 
 Hazel Corylus  An excellent wood when seasoned. Burns fast without spitting. Grade: 4 
 Holly Ilex  A good firewood that can be burned green. Grade: 3 
 Hornbeam Carpinus  Burns well. Grade: 3 
 Horse Chestnut Aesculus hippocastanum  A fairly poor firewood.Grade: 2 
 Larch Larix  A very poor firewood which spits excessively while burning and leaves an oily soot in the chimney. Provides a good heat. Grade: 1
 Lime Tilia  Poor quality firewood.Grade: 2 
 Oak Quercus  One of the best firewoods. When seasoned well, it gives off a good, lasting heat. Burns reasonably slowly.Grade: 4 
 Pear Pyrus  If well seasoned it burns nicely with a pleasant smell. Grade: 3 
 Pine Pinus  Burns hot but needs to be well seasoned. Leaves an oily soot in the chimney and spits excessively.Grade: 1

 Maple (including Sycamore) Acer Burns well. Grade: 3
 Walnut Juglans  Poor quality firewood.Grade: 2 
 Wellingtonia Sequoiadendron  Very bad quality. Grade: 1 
 Willow Salix  A high water content means it needs to be well seasoned. Grade: 2/3 
 Yew Taxus  Usable. Grade: 2/3 

Burning green or unseasoned wood

In simple terms, the word ‘seasoned’ means ‘dry’ and the term ‘green’ means ‘freshly cut from living tree’.

Green wood carries about a third of its weight as water, which on the fire evaporates and helps to carry the heat away up the chimney.  You can often hear a log sizzle or hiss in the fire if it is too green or damp.  Read More

Difference between wood and coal for burning

Wood fuel has typically less than half the calorific value of coal and smokeless fuel which burns for longer, so you must be prepared to use a greater volume of wood to heat your home or room, unless you use both wood and mineral solid fuel. Coal ash should be disposed of in your rubbish, whilst wood ash has many uses and should not be discarded.

Best wood for an open fire

Generally hardwoods are best for open fires because they tend not to spit excessively, however there are exceptions  (horse chestnut spit badly making them a hazard in an open fire). Conifer wood (like spruce) tends to spit excessively when fresh, so is best used for sealed wood burning stoves, again there are exceptions. Many conifers also cause an oily, sticky ‘soot’ to form inside the chimney which can increase the risks of chimney fires. Once properly seasoned conifer wood can be successfully used on the open fire without excessive spitting. Ideally, conifer wood is best mixed with hardwood.

 Where to find firewood

The most common form of wood fuel at the moment is logs. These will usually come from local sources and can be brought from a variety of outlets – e.g. coal merchants, farmers, tree surgeons. There are now companies who only supply firewood.  If you cannot afford to purchase firewood, then why not contact your local Forestry Commission office and enquire about a Scavenging Permit to lift leftover wood after an area has been harvested.  The only other option is to grow your own – however this is a long term investment (unless you buy a mature woodland) some trees grow faster than others such as the fast growing willow Viminalis but the downside is that you have to store them for longer before they are dry enough to burn. 

Buying logs – what you need to know and ask

It is better to buy wood by volume than by weight because between 35% and 60% of the weight of freshly felled wood comes from water. Read More

burning logs in fire

How to make a log fire

In these days of central heating where you push a button or the heating comes on automatically by timer – heating your house with a log burning  or dual fuel stove can be a challenge, and for many is a skill that they have never learned.  As children many of us were warned away from fire, and discouraged from playing with matches.  Our houses were warmed by gas, electricity, or oil.

So you have opened up a fireplace or installed a stove, and are struggling to light that fire or get a good blaze going.  Ray Mears can produce a fire from a spark in the wilderness but you have gone through several matches and firelighters and still there is a pitiful flicker that produces no heat.

What are the tips to lighting a fire?

The things you need to consider are:

  • Air flow or draw of the fire

    Your chimney is the lungs of the house and you need air flow to feed the flames and build up heat.  When we had an open fire this included opening the door in the room, or putting up a sheet of newspaper against the chimney opening to create a rush of air.  In a stove this is easier by opening the vents and door slightly.  Sometimes there are issues about not having enough of a draw – if this is the case seek professional help – a cowl (see link) might be required and on occasion I have heard of a electric fan assisted cowl to artificially generate a flow of air.  If you have an open fire then beware of back-draft when it is windy – sometimes it is just not worth  setting a fire (you can get a cowl to help this see link above).  Or you may have to much of a draw that creates a draft when the pass door is open -(we experienced this which is why personally we prefer stoves).  We have not had a problem with back-draft since we installed the stoves and when the fires are not lit – we don’t have the cold air coming down the chimney.  One last point on an open fire – they are less efficient than stoves because you lose a lot of heat up the chimney.  Stoves retain heat simply from their structure and they enable you to control the rate of burn thereby maximising efficiency.

  • Type of wood you are using to light the fire

  See my other blog on what types of wood burn best.  Most types of wood when unseasoned or green, are too full of sap and water to burn effectively (Ash is the exception).  Also some wood just does not burn very well.  The heavier and therefore denser the wood, the higher its calorific value and therefore the longer it will burn. Hardwoods tend to be denser than softwoods such as pine and spruce and some of the densest are oak and beech. However, some of the very dense hardwoods like oak and elm can be very difficult to burn, so it is usually best to burn them with another type of wood as well. Softwoods tend to be easy to light and to burn quickly (making them very good kindling). Some of the best woods to burn are ash, beech, hornbeam, hawthorn, crab apple and wild cherry.

Your wood needs to be seasoned (dried over a period of time or in a kiln). If buying from a log merchant, check that your load will be well seasoned and ready to throw on the fire.  If you are still unsure, or storing it yourself, use a moisture meter to detect when the timber’s content is below 25%.  Until then, store in a pile with plenty of air circulating around it.

  • Moisture content of wood for the fire

 This can affect how well wood will burn.  Wet wood is also less efficient because the rising steam takes away heat from the room. It will also coat your chimney with resin and soot which is a major cause of chimney fires. More information on this issue can be found here.

  • Size of wood in the fire

 You need to light a small piece of wood and newspaper or firelighter that then lights a bigger piece (called kindling) that then lights a log.  Heat needs to build up and you need a bed of embers burning before logs will burn freely. Check out this You Tube link http://www.youtube.com/watch?v=O6aIeIZfTkg&feature=related

  • Log fires need a lot of attention

They burn quickly and can go out if not attended or fed with other logs.  Coal is a less green option but gives a greater long lasting heat.  However it produces a lot more ash or spoil that is considered toxic and cannot be used in your hen shed or compost.  We put our wood ash under the roosting perches to balance out the acidity of the hen poop. The chicken manure and wood ash react, driving off the nitrogen and drying out the manure. The result is an easily handled, easy-to-store, organic fertilizer that is rich in potassium and phosphorus.  We also add wood ash to the hens dust bath.  Wood ash is a good source of potash check out this link for more info.  For the reasons given we do not mix wood (apart from initial lighting with kindling) with coal, we have one type of fire or the other.

  • Health and safety

Open fires can be more dangerous than wood burning stoves because of the sparks they produce – amongst other dangers.  Never leave an open fire unattended, however stoves can become dangerously hot and touching them or proximity of materials close to stoves can melt, or smoulder.  Fire guards, proximity, and health & safety are things that must always be taken into consideration.

  • Flammable materials

do not burn things in your fire that can cause fumes or are dangerous.

  • Maintenance of chimney

make sure your chimney is cleaned or swept regularly – it is recommended that this is done at least once a year.  Otherwise that roaring fire might turn into something far more dangerous…….  When coal soot deposits or wood tar deposits build up to a sufficient level there is the risk of chimney fire. The heat from the fire warms the deposits releasing the combustible volatiles until they ignite. The fire then migrates up the chimney as the burning deposits heat the chimney above. Chimney fires can damage structures, destroy homes and injure or kill people. Here are some useful links http://www.chimney-cleaners.co.uk/chimney-fires.phphttp://www.stovesonline.co.uk/chimney-fires.htmlhttp://www.youtube.com/watch?v=3drlKFx8P7Y.

We fitted chinese hats to the tops of our chimneys to stop rain getting in, birds getting in, and reduces downdraft.  Check out this link for examples of caps or hats for your chimney.

Making a fire

When your wood is ready, make a wigwam of dry kindling (gathered twigs, chopped up logs, or pallets cut into batons) over scrunched up sheets of newspaper.  Once the paper is lit in several places, this is the foundation of your fire.  Other items that give it extra spark include fir cones, loose or dry bark, or cardboard such as empty toilet rolls. When the kindling is roaring (if using a stove, open up the vent fully or for an open hearth, use bellows to fan the flames), start by adding one log and then more once the fire is established (in a stove leave the vent partially open to keep it steady).  Continue to stir/poke the fire to stimulate combustion and feed with fuel when necessary.

 A log stove can go out quickly if left without fuel, if you wish to stoke up a fire then you need to reduce the air flow and make sure there is plenty of fuel so that it can be left overnight, for example, to burn slowly or smoulder and produce a low heat over a long time.  Hardwoods such as oak are best suited to this as they are dense and slow-burning.

With coal it is possible to pack it down, reduce the air flow, (some people even pour a little moisture over the top to create a crust), and restart the fire again in the morning.  This is less likely to happen with wood as it will burn quicker.

 Wood ash

Unlike coal ash that should be disposed as rubbish, wood ash has many beneficial uses and should be treasured.  Wood ash contains 10-25% calcium, 1-4% magnesium, 5-15% potassium and 1-3% phosphorus. And amongst other things is good for your compost, garden, and chicken dust bath. Read more

Why Grow your own firewood?

Wood is the natural sustainable choice of fuel for many domestic fires – in use since the first fire thousands of years ago. When we warm our homes with wood, we participate in a natural cycle that we share with ancient ancestors.

The ability to burn wood for heat in our homes gives us more control and options for fuel. We are no longer dependent on large energy utilities and multinational corporations whose charges only ever increase. Even if we have to buy in our logs at least we are supporting our local economy.

Unlike the burning of fossil fuels like coal, gas or oil, burning firewood releases no more greenhouse gases (carbon dioxide) than would be produced were the wood to simply rot on the forest floor. If we are responsible in the ways we grow, cut, and burn our firewood, wood burning can actually be a good choice for the environment.

When sourcing wood you have three choices, buy in, buy a mature woodland, or grow your own.  This article will focus on the latter, check out this other article about sourcing wood away from the smallholding.

What trees are the best to grow for firewood?

Note that all woods burn better when seasoned and some burn better when split rather than as whole logs.  In general the better woods for burning that you are most likely to come by are:

  • Apple and pear – burn slowly and steadily with little flame but good heat.  The scent is also pleasing.
  • Ash – the best burning wood providing plenty of heat (will also burn green)
  • Beech and hornbeam – good when well seasoned
  • Birch – good heat and bright flame, burns quickly
  • Blackthorn and hawthorn – very good, burns slowly but with good heat
  • Cherry – also burns slowly with good heat and a pleasant scent
  • Cypress – burns well but fast when seasoned, and may spit
  • Hazel – good
  • Holly – good when well seasoned
  • Horse Chestnut – good flame and heating power but spits a lot
  • Larch – fairly good for heat but crackles and spits
  • Maple – good
  • Oak – very old dry seasoned oak is excellent, burning slowly with a good heat
  • Pine – burns well with a bright flame but crackles and spits
  • Poplar – burns very slowly with little heat
  • Willow – good if seasoned well

Timescale for harvesting wood as fuel

If starting from scratch then the quickest tree to plant and harvest is willow.  It can be grown on damp unusable ground, and if properly undertaken, will produce wood of a size that is manageable by a smallholder without specialist equipment.

Willow as firewood

Pros

Super fast growing varieties can produce logs up to 3 inches or more thick in only 5 years.  It is best to cut or coppice in the dormant season from late autumn to late winter.  This ensures there is the least quantity of water within the coppice poles, which reduces the time taken to season the firewood to a minimum.

To get reasonably sized logs you will have to coppice your willow every 4-5 years.  The advantage of short rotation coppicing has always been the small diameter of the trees which enabled them to be worked with hand tools.  The production of firewood is best carried out using the coppice system  because a felling licence is not required to cut coppice poles with a diameter at breast height (1.3m from the ground) of 15cm or less.

Cons

Willow wood is mostly water and takes a long time to dry out.  Some other woods will dry all on their own, simply as a function of time, but the willow dries best with good access to a breeze. Otherwise it can rot or start to grow again before it drys out.  If it sits outside and get’s rained on, it will soak up water like a sponge even if it was previously “dry”. Willow has to be kept dry- in other words, kept under cover. It should dry for a minimum of six months, but letting it dry for two to three years improves its performance slightly.

Willow is very soft wood and it burns very quickly so mix it in with your other firewood because it won’t last long.

Coppicing trees 

Many species of tree can be coppiced (e.g. hazel). This involves regularly cutting the tree down to a stump called a stool. Multiple new shoots (known as poles) regrow from the stool. The cutting is done on cycle so to keep a consistent supply you need to plan ahead and have sets of trees which you cut each year. The interval between cutting depends on the species of tree. The trees are cut during the winter before the sap has risen, and the branches are all cut low to the ground. By repeatedly cutting the trees their lifespan can be greatly increased. One of the advantages of coppicing is that you do not need to replant the trees every time you cut.

The new growth is fairly straight and manageable, and can grow very fast. Because the wood from coppicing is relatively small it also takes less time than large logs to season and you should easily be able to season it over one summer. Coppiced firewood can be burnt in a wood stove and is ideal for use in gasification / batch boilers – these boilers have very larger fireboxes which can take long length logs. You fill up the firebox and the boiler burns the fuel transferring the heat to a heat storage or accumulator tank for use when needed.

Many types of deciduous tree can be coppiced: Alder, Ash, Beech, Birch (3-4 year cycle), Hazel (7 year cycle), Hornbeam, Oak (50 year cycle), Sycamore Sweet Chestnut (15-20 year cycle), Willow, Sweet Chestnut, Hazel (7 year cycle), and Hornbeam. 

Turning trees into firewood

Once you have harvested your wood you must split any logs that are more than 6 inches in diameter.  This increases the surface area of the wood exposed to the elements and therefore enhances drying.  You can get mechanical splitters, and attachments for a tractor, when you have large quantities to split, but they are not cheap.

For the average user or smallholder a maul is the tool needed.  It is a type of axe with a heavy wide head especially for splitting logs.  A maul does not need to be particularly sharp – unlike a narrow felling axe which slices at wood and needs to be sharpened regularly.  You can use a felling axe for splitting logs but it is much harder work than a maul.  The trick with a maul is to let the weight of the head do the work – swing the maul over your shoulder and let the head fall on to the log without forcing it down.  The wide head will force the log apart.  It’s also important to have the log you are splitting at a good height – on a tree stump or larger log about 18 inches to 2 feet off the ground is ideal – this makes the job easier and avoids back damage.

Kindling

Trees and shrubs suitable for kindling include:

  • The older wood or prunings of Buddleia
  • Gorse -as a fuel it has a high concentration of oil in its leaves and branches, and so catches fire easily and burns well, giving off a heat almost equal to that of charcoal.
  • Lilac: Thinner branches make good kindling, whilst the thicker burn well with a clear flame and a very pleasant smell.
  • Rhododendron: Old thick and tough stems burn well.

Benefits of willow

  • Properties of Willow 

    Willows will grow in a range of habitats and survives in most localities.  In soil of pH 6.0 – 8.0  Most soil types. Most topography.

     

    There are species of Willow, which are adapted to different conditions:

     

    S. alba – low lying conditions

    S. fragilis – river bank

    S. herbacea – mountains Scotland

    S. repens – colonises sand dunes

 
Willows are the fastest growing & highest yielding tree or shrub in Britain. When grown as Short Rotation Coppice they can produce as much as 10 to 15 tonnes of dry wood per hectare per year and often more on the better sites.
 
Farmers are now growing willow to supply power stations with a natural, renewable and carbon neutral source of energy. It is usually harvested on a 3 year rotation then chipped, dried and loaded into giant hoppers to be fed automatically into the boilers to produce electricity and/or heat.
 
For a smallholder or householder though, logs are more useful than woodchips. Known as the 5 year Coppice Rotation, a site is divided into 5 beds and 1 bed is harvested each year, providing a regular supply of firewood year on year.
 
Using this system, 500 plants on 750 sq m (less than a fifth of an Acre) can produce 1 Tonne of dry firewood every year.

Planting willow

These plants are delivered as setts – unrooted cuttings.  Willows should be planted during the time when they are dormant, i.e. after the leaves have dropped and before the sap starts to rise again.
 
As they need to develop a good root system, before they can afford to develop leaves, willow cuttings should be planted between December and the beginning of April and willow rods should be in the ground by the beginning
of March.
 
They establish rapidly in any soft earth, free of weeds.  Soak them in water overnight, then plant them to about half their depth, coloured end pointing upwards. Cut back half the new growth in the winter after planting to make them bush out.

  • Healing

Country folk have been familiar with the healing properties of willow for a long time. They made an infusion from the bitter bark as a remedy for colds and fevers, and to treat inflammatory conditions such as rheumatism. Young willow twigs were also chewed to relieve pain. In the early nineteenth century modern science isolated the active ingredient responsible, salicylic acid, which was also found in the meadowsweet plant. From this the world’s first synthetic drug, acetylasylic acid, was developed and marketed as Aspirin, named after the old botanical name for meadowsweet, Spirea ulmaria.

  • Bee Fodder

Willow benefits pollinating insects in early spring. Willow plants when flowering produce both nectar and pollen. Females give only nectar, but male plants give both nectar and pollen. Planting a variety of willow types, will give an extended flowering season. The Salix Viminals often flowers in April, at the end of the period that is crucial to honey bee brood building time.

  • Willow is a good supplementary feed for sheep and lambs, it also helps them cope/expel/resist worms.

 

Willow links with Scottish place names 

The Gaelic words for willow are shellach, or suil, and feature in Scottish place names such as Achnashellach in Ross-shire, Glensuileag in Inverness-shire and Corrieshalloch on Speyside. These names would have referred to both the presence of willow and the attendant industries utilising the willow’s gifts.

timber damage after storm at fife smallholder

The relationship between Beech, Bats, Woodpeckers, Owls, and Pigs on our smallholding

‘Piglet has his own house, a “very grand house in the middle of a beech tree,” which he gave to Owl when his house was blown down on a very blustery day’ .

large beech trees in winter
We have some large Beech sentinels in our wood that are estimated to be 190 years old, and one of them suffered damage in the recent high winds that hit Central Scotland.  The limbs on these trees are very large and although unfortunate it does offer opportunities from the adversity.

Firewood

Beech wood is an excellent firewood, easily split and burns for many hours with bright but calm flames.

Woodlander

Beech wood burns well and can be used to smoke herrings and cheese. Chips of beech wood are also used in the brewing and making of some beers. 

Wildlife

Although a fallen limb or tree is good for firewood, it is also a part of the natural process within a wood and many species depend on this happening to maintain the balance and ecosystem that exists within a woodland.  The larger the concentration of old trees in an area and the longer they have been present on site the richer the variety of species you will find among them.
Many species live here all year round. Some are visitors and some live here permanently. Some come for the spring (Great spotted woodpecker), summer (Insects: Hoverflies, Birds: Green woodpecker), autumn (Fungi), and others for the winter months (such as Brambling birds ). Because of the variety of habitats available. A range of birds use the broad leaved woodland, evergreen conifer, open rough grassland and low bog areas.

Beech mast and Beech leaves

Beech mast is also a favourite food of many woodland animals such as badgers, deer, mice and squirrels and birds. The leaves are eaten by caterpillars.

The laughing woodpecker

The Green Woodpecker is the largest of the woodpeckers and has been known to visit our woods and its collection of fallen and rotten timber. It has a heavy-looking body, short tail and a strong, long bill. It is greeny-grey on its upperparts with a bright green rump and red on the top of its head. They have an undulating flight, and will climb up tree trunks and branches and will move around to be on the side away from anyone watching. It has a very distinctive call in that it sounds like it is laughing.

Relationship between bats and woodpeckers

Tree are vitally important for our bats. The majority of British bat species have been recorded roosting in trees and some, such as the Noctule, rely almost exclusively on them. Noctules are often found in Woodpecker holes appearing to prefer them over natural cavities. Some researchers have suggested that Noctules may be dependant on woodpeckers to provide suitable roosting opportunities. Read more about bats.
potential bat roost in old woodpecker hole in tree
The picture shows an old woodpecker hole which could be used by Noctules for roosting. The hole is formed in a soft section of the stem of a tree. The stem has been infected by a decay fungi which has caused the wood to become soft enough to allow the woodpecker to create the hole. This potential roost has been created by a complex ecological relationship between Beech tree (Fagus sylvatica), Tinder fungus (Fomes fomentarius) and woodpecker, possibly the Green Woodpecker (Picus viridis).  It isn’t just roosting opportunities that make beech trees useful for bats. The trees attract insects and therefore provide valuable foraging habitats.

Bats and Beech

Bats roost in trees, in obvious cavities, cracks and splits, but also in less obvious places such as under ivy and under loose bark.  The damaged parts of a tree are the most likely places to find roosting bats.  Any tree can be used for roosting as long as shelter is provided,  but old oak, beech, ash and Scots pine are most frequently used. Bat roost sites can be at any height, although the upper trunk and branches are favoured. Entrance holes may be narrow slits on the underside of a branch that can be easily overlooked, as well as more obvious old woodpecker holes in the main trunk.

Owls and Beech

One of the best trees to attract owls is the beech tree. That’s not because owls eat the beech mast, or beechnuts, but because the mice eat them. In this way, the carnivorous owls get nice, fat, juicy mice to eat to keep them in the area.
beech nut casings
“As long as owl’s habitat is left alone by man and in such a state as to produce a great number of rodents, there will be no loss of owls in a region. One of the things that those people managing woodlands can do is not to clear out all of the undercover where mice live. Tawny owls will particularly benefit from this practice. Wood left on the ground and a pile left to rot will draw all kinds of insects which also feeds owls.”
decaying wood attracts insects that are predated by owls

Livestock

Pigs and Beech

Livestock were once released into beech woodlands to feast on the beech’s oil-rich bounty. The nuts were also important as a source of food, particularly for pigs. They are energy rich and could be used to fatten pigs up for market. The period when the nuts ripened and fell was perfectly timed to fatten swine for late autumn butchering. A farmer with access to oak or beech mast could thus convert calories present in nuts into calories in pork with little or no additional effort and at no additional cost in fodder. Indeed, by using mast rights a farmer was able to make use of a resource that would otherwise be unharvested or very inefficiently harvested.

Pheasants, Poultry, Turkeys and Beech

Beech mast has also been used to feed pheasants, poultry, and turkeys.  Beech nuts should never be fed to horses.

Smallholder

It is commonly accepted that the foods used to feed and to finish meat livestock affect the final flavour of the product. Pigs  fed on oak mast, chestnut mast or beech mast has a reputation for producing exceptional finished meat. As a result, with the new interest in artisanal and high quality foods as well as humane stock handling, there is a resurgence of mast-fed pork.
While beechnuts are nutritious for humans, eating too many can cause headaches or giddiness, as vast amounts of potash are contained within the tree.

Beech Tree facts

  • Beech trees are shallow rooted, and mature trees are at risk of being uprooted in high winds.
  • These trees grow slowly, eventually reaching a height of up to 120 feet, with branches spanning 50 feet.
  • The nuts are encased in a spiny bur and are favored by birds and other wildlife. Beech has a full crop of nuts every 5 years but does not really start producing a good crop until it is at least 50 years old.
  • The timber is practically pure white and is used to make furniture and toys.
  • The tree is best known for its many and low branches that create a deep shade.
  • Beech leaves take a long time to decay, so few nutrients are released to nourish ground plants. Consequently, there is little undergrowth in a beech wood, unless trees have been deliberately thinned out (coppiced).

Folklore

names on a tree trunk

Magically, beech is specifically useful for making wishes. To do this write a or scratch your wish on a piece of beech wood then bury it in an appropriate spot.  As your written wish is claimed by the earth so will it begin to manifest in life.  Beech is also popular with lovers, as witnessed by the many hearts arrows and names carved upon the smooth trunks of beech trees.

Recipe

Beech leaf Noyau

1 bottle vodka
225g (8oz) caster sugar
1 glass of brandy
Collect young, fresh beech leaves and strip them from the twigs.  Half fill an emptly bottle or jar with the leaves  and then pour on the bottle of vodka.  Seal up the container and keep leaves in it for 3 weeks, before straining them off.  Boil the sugar in half pint of water and add this to the vodka with a good sized glass of brandy.  You should end up with 2 almost  full bottles of noyau for the price of one bottle of vodka.

hawthorn logs gathered on smallholding for winter fuel

Gathering logs on the smallholding for fuel

Today we have been gathering up logs, that have been sawn up for winter fuel.  These logs will not be used this winter, but will be stacked and allowed to dry out ready for use next winter.

Information about hawthorn

We have many Hawthorn trees in our wood, and this was one that was past its best.  Hawthorn wood is hard-wearing and often used in the past to make handles for knives and daggers.  No wood burns more readily than hawthorn, even when green, and it is known as the hottest firewood.  Excellent charcoal is made from hawthorn.  Here in Scotland the bark was used to dye wool black and in most country places hawthorn leaves were used to make a refreshing tea.  Hawthorn flowers can be added to syrups and can make a lovely wine.

Hawthorn and blackthorn both have the character for a good hedge: they are easy to germinate, quick to grow and capable of being trained in any direction.  if haws, from the hawthorn, are put in a bag and soaked in water all the winter and then sown in February or March, they will come up the first year.

Hawthorn berries are popular with wild birds. For information on flowers, pollinators and insects that are attracted to the hawthorn click here.

Hawthorn Folklore 

Hawthorn is linked to May Day ceremonies and was believed to protect people and livestock from evil influences and lightning: and witches too, who get tangled up in the prickles.  Never bring May (hawthorn blossom) indoors, though.  Because of its association with Christ’s crown of thorns it is thought to bring death to the household.
