Things to do in your
Mapesbury garden in May:
Continue to weed the borders
with either a hand fork, or by using a hoe on a sunny dry day, the
weeds will wilt and die in situ.
Rhododendrons, Camellias, tulips etc once flowered, this will
encourage the plant to concentrate itís energy on producing next
yearís flowers, rather than seed this year.
Hostas and Delphiniums are
particularly attractive to slugs and snails. Deter using Ferrous
phosphate slug pellets, which claim not to harm any vertebrates.
Finish staking tall summer
flowering perennials, before they grow too large.
Feed Spring bulbs while
still in leaf, with tomato feed or sulphate of potash. Allow the
leaves to turn yellow before cutting down as they contribute to
making food for the bulb.
Carry on planting Summer
bulbs e.g. Gladioli & Dahlias.
Plant out Dahlias around mid
to the end of May and protect young shoots from Snails.
Pull up i.e. Myosotis
(forget-me-nots) once flowered to stop them seeding all over the
Prune Spring flowering
shrubs like Kerria japonica, which will benefit from the removal of
roughly a third of the stems from the base, thus encouraging new
Clematis can be a bit unruly
at the moment with all the new growth, so tie in.
Be vigilant for pests like
aphids, Vine weevils, Lily and Viburnum beetles.
When it comes to mowing the
lawn, little and often is the way to go.
Continue to remove blanket
weed from ponds.
