Gardening for bumblebees
Wildflowers have become scarce in the
countryside because we've lost many traditional habitats like hedgerows, hay meadows
and chalk grassland. The extensive use of pesticides in farmland has
also drastically reduced wildflower numbers. As a result, wildlife gardens have become a
stronghold for some bumblebee species. Wherever you live in the UK, you should be able to
attract at least 6 bumblebee species to your garden, and perhaps as
many at 10.
Bumblebees need flowers throughout the
Spring and Summer (March-Sept), and these need to be the right kinds
of flowers. Exotic or highly cultivated
garden flowers are largely unsuitable, as they either produce little
pollen and nectar, or keep it hidden away from the bees.
In
particular, most annual bedding plants (e.g. Pelargonium,
Begonia, Busy Lizzies) have little nectar to offer bees or other
wildlife. Instead, why not try
growing traditional cottage garden flowers and native wildflowers. Many of these
thrive and look superb in the garden. They are also easy to grow,
generally being hardy and much more resistant to slugs and disease. Bumblebee species differ in the
length of their tongues, and as a result prefer different flowers,
so it's important to grow a range of different things.
Below you'll find a selection of both garden and wild flowers that
will bloom throughout the year. They are all types that bumblebees
love, and will cater for both long and short-tongued species. If you
have room for even one or two of these they will attract many bees.
Most of these plants will also attract a range of other interesting
insects to the garden, including butterflies and honeybees. |

Viper's bugloss (Echium vulgare) - Perhaps the very best plant to attract bumblebees to your garden.
Much loved by almost all species, and it looks great too. Flowers
June-August. |

Wildflowers for bumblebees |
 |
One of the simplest things you can do to help your bumblebees is to leave an area of your lawn uncut during the summer. If you don't mow between late-June and early-August, your lawn will burst into flower with clovers and birds-foot trefoil. This needn't look untidy - make it an interesting shape, and border it with a mown path so that you can enjoy watching your bumblebees foraging away.
When you do finally cut, in August, remove all of the clippings and put them on the compost heap. Over time, this will allow the soil fertility to drop naturally, which will encourage the wildflowers to flourish - they actually prefer nutrient poor soil.

Many wildflowers
have become scarce in farmland. If you make space for
them in your garden the you'll be helping conserve both
the flowers themselves and the creatures they
support. Many of these native wildflowers are
extraordinarily beautiful – it’s not all about nettles
and brambles! We often forget that many conventional
garden flowers such as foxgloves are native wildflowers.
Seeds of some wildflowers like foxgloves and cowslips can be bought in most
garden centers, but the range is usually limited. A far greater
selection are available by mail order from specialist companies.
However, there is a lot to be said for collecting the seeds yourself
from the wild. Most plants produce thousands of seeds, but there is
nowhere near enough room for them all to germinate and
grow. Collecting a few seeds will have no impact on the plant population in most cases.
There is
a very strong conservation argument for using local seed as you are
helping to propagate and conserve the local race of the plant species, so if possible gather your
wildflower seed from close to home.
Before going out collecting, remember
that collecting from private land or nature reserves is
illegal. However, this is generally not a problem
because many wildflowers can be found along road verges
or riverbanks. Secondly, do not collect seed from rare
plants or from places where there are only a handful of
parent plants.

Why not make
space in a corner of your garden for a beautiful
wildflower meadow? |
Collecting your own seed requires patience, as it is
necessary to wait for the right time of year. Try to
spot the location of flowers and then return when the
flowers have set seed. Most wildflower seed is very easy
to collect. For larger seeds simply pick them up with
your fingers; for example tufts of knapweed or thistle
seeds are readily plucked from mature seed heads. For
others, the best approach is to place a bag over the
flower head and shake. Once collected, keep the seeds
dry and cool until you can sow them. Generally it is
best to sow the seeds immediately, since this is the
time at which they would naturally be scattered. Place
in seed trays outside since some seeds will not
germinate without passing through a cold winter (or a
simulated cold period). |
