The
Pollinator population:
bolster your bees and butterflies
With a plethora of scientific studies confirming the fact that
populations of wild bees, butterflies and other insects are in
dramatic decline, many gardeners are wondering what simple steps
we can take to make our own little patch of paradise more pollinator-friendly,
Here are some handy tips to get you started.
Garden a little on the wild side
For example, by allowing a patch of nettles to colonise a small
corner, you're providing food for the larvae (caterpillars) of
once-common butterflies such
as the small Tortoiseshell, Red Admiral, Pea- cock and Comma, all of which
lay their eggs on its leaves. By allowing even a narrow ribbon of lawn to grow
uncut, you're helping the Speckled Wood, Wall Brown, Grayling, Gatekeeper,
Meadow Brown, Ringlet and Small Heath butterflies, which depend upon various
native grasses as a source of food for their larvae.
Long grass also provides the perfect habitat for wild bumblebee nests, while
many of the common wild flowers happy to grow in it, such as dandelions, clover,
celandines, buttercup and primroses, are also valuable sources of food for pollinating
insects. Alternatively, consider mowing your lawn less often, or transforming
sections of it into a wildflower-rich meadow by sowing seeds of yellow rattle
into it in early autumn. This wonderful little wild flower naturally robs fertility
from over-vigorous species of grasses, allowing lots of daintier, pollinator-friendly
wild grasses and flowers to thrive in their place.
Grow plants for all seasons
While summer is time of abundance, resident pollinating insects
need a steady supply of nectar and pollen from the moment they
wake up from their winter
hibernation in early spring and take wing in search of food. Autumn-flowering
plants are equally important, coming at a time when many are preparing once
again for hibernation. So by growing a few spring-flowering garden plants such
as hellebores, lungwort (Pulmonaria), honesty (Lunaria) and flowering currant
(Ribes), and some autumn-flowering species such as dahlias, sedum, Michaelmas
daisies and joe pye weed (Eupatorium), you'll be giving them a helping hand.
Meanwhile, by growing a few pots of snowdrops and crocuses, or allowing wild
ivy to colonise a small patch of your garden, you're providing food in the
lean months of late winter and early spring, when rogue warm days make honeybees
take flight and tempt bumblebees out of hibernation.
Try to avoid using chemicals
Especially avoid those containing what are known as neonicotinoids or neonics,
a common ingredient in many over-the- counter insecticidal sprays as well as
in some pre-treated seed. Similarly, avoid using weed killers and fungicidal
sprays. None of these are good for pollinating insects or indeed, for humans.
Choose single flowered plants
If you're new to gardening, these terms can sound a little bamboozling,
but don't panic. They're just ways of distinguishing between
flowers with relatively
few petals (single-flowered) and those with lots and lots of them (double-flowered).
The latter aren't much use to pollinating insects as their profusion of petals
makes it very difficult to access the flowers carbohydrate-rich nectar and
protein-rich pollen, which they rely on for food.
Examples of "open-faced" or single-flowered garden plants include
many species-type roses, both the species-type and Bishop-series of Dahlias,
and many varieties of cosmos.
Grow some native trees
It can be easy to forget that the nectar and pollen of the flowers of many
common garden trees are abundant sources of food for pollinating insects,
especially those that bloom in late, winter or spring.
Examples include the native hawthorn, hazel, alder, rowan, crab apple, willow,
horse chestnut, ornamental cherry and most fruit trees. The flowers of many
common garden shrubs such as berberis, forsythia, potentilla, lavender, rosemary,
mahonia, viburnum and cotoneaster are also excellent sources of food.
Plant
a butterfly bush
The large, nectar-rich flower spikes of Buddleia, this hardy, deciduous shrub
appear in late summer and are so attractive to butterflies that it's not
unusual to count dozens of them feeding from a single plant. Depending on
the particular variety, those decorative flower spikes can be dark purple
('Black Knight'), pink ('Pink Delight'), white ('White Profusion'), purple-red
('Royal Red'), or even multicoloured (B x weyeriana 'Bicolor'), but bear
in mind that butterflies are naturally drawn to flowers
in shades of orange, purple and dark pink.
Although typically a large, slightly sprawling shrub, new ultra-compact forms
such as the Podaras series are perfectly suited to container growing.
Provide different habitats
For example, some of our native species of wild bee like to overwinter in the
hollow canes of raspberries or the dead flowering stems of perennials. Others
prefer sunny, raised banks, or rotting tree stumps, or the bases of hedgerows,
or the cavities of stone walls.
Likewise, hibernating butterflies need a sheltered spot in winter - perhaps
an old outbuilding, a hollow tree stump or even the eaves of a roof. Habitat
loss in the wild is one of the greatest causes of pollinator decline, so the
greater the variety you can provide in your garden, the better.

Hawthorn
(Crataegus monogyna) Sceach Gheal
The
Hawthorn, by its Latin name Crataegus monogyna,
is also known as Quickthorn, Whitethorn, the May tree or by its
Gaelic name Sceach Gheal. It is one of the most
common small trees/large shrubs grown in Ireland. It is sometimes
grown as individual trees, but it is more common to see it grown
in a
closely planted row as a hedge or screen. It is the ideal candidate
for this, as young hawthorn plants grow strongly with many thorny
branches and side-shoots. This quickly forms a thicket, which makes for
a virtually stock-proof hedge.
