pollen

What is nectar?

Nectar – nectar is loaded with sugars and is a bee’s main source of energy.

What is pollen?

Pollen – pollen provides a balanced diet of proteins and fats.  

Bees forage for both nectar and pollen from plants and flowers.  Dry pollen, is a food source for bees, which contains 16 – 30% protein, 1 – 10% fat, 1 – 7% starch, many vitamins, but little sugar.  Bees mix dry pollen with nectar and/or honey to compact the pollen in the pollen basket. The protein source needed for rearing one worker bee from larval to adult stage requires approximately 120 to 145 mg of pollen.

“An average bee colony will collect about 20 to 57 kg (44 to 125 pounds) of pollen a year.”

Pollen comes in different colours and you can see it either dusted on the bee, in the pollen sacs on the bees leg, or stored in the beeswax foundation along with honey and brood.  Each plant produces a different pollen colour and because honeybees collect pollen from only one source at a time it is easy to see the colours. The bee adds a tiny amount of nectar to the pollen as it collects it which makes the pollen stay on the bee’s pollen basket or sac, which is in fact on just one strand on each rear leg.  However, bumblebees’ pollen sacs don’t have similar colours, because they  gather pollen from a variety of plants so the colours are mixed up.  

Here is a link to a pocket pollen colour guide that will help with your identification.

Why do pollinators collect pollen?

“So why do bees collect pollen? It is a source of protein, fat, starch and vitamins and fed to bee larvae along with honey and a little of what is called queen jelly, a secretion from the glands in the heads of worker bees.”

The nectar is the bees source of energy while the pollen is consumed because it is a source of protein and other nutrients and is feed to growing larvae.  In the process of collecting pollen and nectar they inadvertently fertilise flowers, trees, and plants (read more).

Plants can attract pollinators through scent (e.g. moths find flowers at night using the smell) or colours (bees are more attracted to some colours e.g. blue, purple, violet, white, and yellow).  Some bees also have a special connection with certain flowers. These bees are called oligolectic and it means that you will see the females gather pollen only on a few species of plants. For more information on the different types of bees and what plants they like click here.

Bees are a big help to plants that flower because they help with pollination. When honey bees land on a flower to drink its nectar, pollen grains stick to its legs and bodies. Then, the pollen rubs off on other flowers and helps them reproduce.
 
“The importance of garden plants yielding nectar and pollen is that together they provide a continuous food supply from early spring to late autumn. Colonies of bees need food through their active season , so that they can develop and rear new bees. “

What to plant to attract pollinators, insects, bees, moths and butterflies to your garden

Bees and other pollinators are active in the fifesmallholder garden and woodland, from very early in Spring until the Autumn frosts.  Sometimes, if you are lucky you might see a bumble bee flying in a warm winter day but rarely a honey bee. Moths and butterflies are also seasonal, some overwinter and others migrate here in good weather. In order to make sure that there is always pollen and nectar available, it’s important to have suitable plants in flower, at the appropriate time. 

“We used to have 27 species of Bumble Bee in Britain, two have become extinct in the last 70 years and several more are on the critical list.”

As well as providing bee friendly habitats and nesting sites why not join the Bumble Bee Conservation Trust  and/or your local Beekeepers association

“Bees and butterflies hibernate in winter, so don’t forage when it’s truly cold. But it’s good to have a few winter-flowering plants that bees can use on warmer days and a regular food source from March to November.”

Plant flowers in groups

Flowers clustered into groups of the same species will attract more bees than individual plants scattered through the border. Where space allows, make the clumps four feet or more in diameter.

“if you plant them they will come”

What is pollen and nectar?

Nectar – nectar is loaded with sugars and is a bee’s main source of energy.

Pollen – pollen provides a balanced diet of proteins and fats.  

Bees forage for both nectar and pollen from plants and flowers.  Read more. 

 What Is A Pollinator?

Here in Britain ‘pollinators’ means small flying insects such as hoverflies, bees, beetles, butterflies and moths.

 What do I need to plant for nectar and pollen?

 

“Most bedding plants are absolutely useless for bees and so are most with double flowers.”

Research suggests native plants are four times more attractive to native bees and pollinators. They are also usually well adapted to your growing conditions and can thrive with minimum attention.  Below is a list of plants and flowers suitable for pollinators and include pictures of ones that grow in our garden and woodland.

“Single flowered cultivars (some are marked as ‘Single Flowers’) are more useful to bees than double flowered cultivars.”

spring yellow flower

Yellow Gorse / Whin – (onn) – Ulex europaeus

Here at fifesmallholder we like to keep our gorse, whereas next door the farmer annually cuts it back or burns it.  He probably does this to control the growth and spread of the gorse because it reduces his grazing and can cause health issues with his sheep (Orf can be caused through the wounds inflicted by eating gorse and other prickly vegetation).

Why do I keep it?  

  • the deer will stamp on it and eat it in the winter (the stamping reduces the threat of the thorns or prickles)
  • it is a safe habitat for some wild animals (e.g. hares or small birds)
  • the bees, insects and pollinators love the pollen in the spring
  • dry gorse is a good fire lighter
  • a gorse branch can be used to fill a hole in the fence or hedge
  • I love the smell of coconut when it is in full bloom and will make gorse wine from the flowers (you can download a recipe here)

What is gorse?

Gorse is a bushy, dense evergreen spiny shrub and will grow up to 2 meters tall. It’s a prickly shrub, which can almost always be found in flower somewhere, all twelve months of the year, and this means it has many positive connotations in folklore. It prefers poor grassland, mainly acid soil,  and drier ground. It can grow in nutritionally poor soil, is drought and salt spray tolerant, preferring a full sun position. In leaf all year and flowering all year, the seeds also ripen all year, however a burst of flowers occur in the UK between February to May.

Gorse is closely related to Broom and both are members of the pea family.  It has green stems and very small leaves and adapts to dry growing conditions, but differs from Broom in its extreme spininess, with the leaves being modified into 1-4 cm long spines. All the species have yellow flowers, some with a very long flowering season.  In hot sunny weather in April and May the seed-cases of gorse burst open with a crackling, popping noise, scattering the small dark and round seed sup to 30 feet in all directions. Reproduction is mainly by seed, with each seed having a hard water resistant coat that prevents immediate germination. Gorse seeds can be dormant in the soil for 40 years and still germinate.  Gorse can live up to 30 years.

Can gorse be used as animal fodder?

Gorse provides excellent food for goats, cattle, horses and sheep (it has half the protein of oats) and it is said increases the milk yield of cattle. It gives peak fodder production from the end of November to the end of February arriving just in time to repla­ce exhausted autum pastures (cut right to the ground but harvested only once every 2 years, only the top of the plant is used for fodder).  However it is not advisable to use without treatment such as being crushed or rolled first. Or dried and hung in the stable/barn to supplement Winter fodder. 

What other uses are there for gorse?

  • It’s bark produces a green dye and flowers a yellow dye.  Add a bucket of urine and wait 3 hours.
  •  its roots for basket weaving
  •  chimney sweeping
  •  green manure – gorse is member of the legume famlily, and so it has nodules in the root system that fix nitrogen from the atmosphere. Coppicing the gorse releases some of the nitrogen making it available to other plants near the roots space.
  •  fuel – the very high concentration of oil in it’s branches, makes it easy to ignite, and also burn well, it is reputed to give off almost as much heat as charcoal.  When harvested for fuel gorse is usually cut down to ground level, as a three year rotation.
  • The ashes were used to make lye for cleaning linen (the alkali rich ashes produced from burning gorse have been for soap-making in solution as lye which was mixed with animal fat).
  •  roofing 
  • Gorse seeds have been soaked, then used as flea- repellant
  • Gorse flower buds are reputed to make a fine pickle in vinegar and then used like capers in salads
  • Gorse flowers have been used to add extra flavour and colour to beer, whisky, wine and tea
  • Sprinkling gorse sprigs and holly leaves in a seed row will help deter small creatures such as voles and mice from digging up your seeds
  • Alkali ashes also are very enriching to the soil, so in the past gorse was often burnt down to improve the quality of the land, that also caused new growth which grazing stock could eat. However, burning the oil rich gorse can be a hazard in dry weather
  • walking sticks canbe made from the gnarled branches
  • Gorse is a good windbreak and a gorse bush is the best place to dry washing – it naturally pins it in place.
  • Gorse protects against witches.
  •  Planted for soil stabilisation in sandy areas with maritime exposure, it is fast growing, puts nitrogen back into the soil and provides conditions for woodland trees to become established.

Every smallholder should have at least one hive of bees

My garden and wood are well stocked with bee friendly plants and flowers, I have been known to follow bees round a garden centre and buy whatever they land on.  Plants for bees is one of my passions and I love to see them on a flower or shrub.  A consequence of this is that the moths, butterflies, and bumble bees benefit too.  Win win.  From January to December I have something in flower just in case they need nectar or pollen.

So ………. when all this well stocked larder is open to them, why do they choose to go to a flowering weed ?  :0)
