Dandelion Days – May 2008

Common Dandelion – Good source of Pollen
May has been dominated by dandelions on the roadsides – which provide lots of pollen and nectar for bees – though the vast yellow fields of oilseed rape (OSR) provide pollen and nectar on a totally different scale. Sadly the Oilseed Rape flowered too early for our colonies to take advantage of – my hives are stuffed with hatching bees and sealed brood – but there just aren’t enough foraging bees to ‘cash-in’ on the golden harvest of OSR. The newly emerged bees will spend at least two weeks inside the hive feeding larvae, cleaning cells and acting as ‘house bees’ – receiving nectar from foragers – before they start to go out and collect nectar themselves. However, this vast bloom of flowers is the perfect source of food for accelerating the build-up of the bee population in the hives.

Honey provides the bees with their daily food needs – but they can only create new bees if they can provide larvae with protein in the form of pollen. Thus -in Spring the hive usually has stores of honey – and some stores of ‘sealed-pollen’ (last season’s pollen mixed with honey as a paste – sometimes called ‘bee bread’.
However, the limiting factor on breeding more bees is the availability of pollen. So May is the crucial month here in the UK when vast swathes of wildflowers and huge crops of oilseed rape provide an ocean of pollen. The problem is that the hive needs foragers – older bees – to collect the pollen, and if the hive population is still low, there just aren’t enough pollen-foragers to do the job.
