Lilac and cherry bloom in May
And soon the trees are clothed with leaves
Before the month has passed halfway
Winter's blast is summers breeze
Plants of interest (my selected varieties of
trees, shrubs, annuals and perennials)
 | Aquilegia vulgaris varieties, |
 | Veronica prostrata, |
 | Exochorda giraldii small tree festooned with paper-white flowers, |
 | Laburnum the golden rain tree, |
 | Wistera sinesis, |
 | Meconopsis betonicifolia, |
 | Ceanothus 'Cocha' one of the best wall shrub varieties with bright blue
flowers, compact habit, |
 | Ceanothus 'Cascade', |
 | Ceanothus 'Blue Mound', |
 | Ceanothus thyrsiflotus repens the creeping blue blossom, |
 | Dicentra spectabalis alba, |
 | Verbascum 'Gainsborough', |
 | Convolvulus cneorum, |
 | Viburnum plicatum 'Mariesii', |
 | Laburnocytisus x adamii a very attractive and unusual tree or wall shrub.
This tree is a cross between two genera (a by generic hybrid) the
Laburnum anagyroides and Cytisus purpureus, the result is a tree that bares
three types of flowers. Yellow flowers of the Laburnum, purple flowers of
Cytisus (Broom) but most of the branches produce intermediate flowers

Key tasks to undertake
 |
Remove spring flowering bedding and bulbs, prepare the
ground for summer bedding. |
 |
Plant out summer bedding plants towards the end of the
month, visit the University of Cambridge, Gardening Service,
Plant Sales.
Plant scented plants near doors, windows and near areas where you sit. |
 |
Support herbaceous plants while they are small. |
 |
Apply a selective weed and moss killer to weedy lawns
this month. |
 |
Some hedges will want their first cut, it is essential
to cut some hedges regularly as a neat hedge contributes greatly to the
overall appearance of the garden, let it grow untidy and the garden will
look unkempt. |
 |
Mow the lawn regularly, water if necessary and remove
odd perennial weeds by hand or cut through them with a knife. The best lawns
are achieved by regular mowing, removing all grass cuttings as you mow and
feeding several times a year. |
 |
Feed daffodil bulbs to build up next years flowers. |
 |
Plant up hanging baskets, include long lasting slow
release fertilizer and water retaining granules in your basket compost. This
will save the task of having to include a liquid feed when you water and
watering should be slightly reduced. |
 |
Repot greenhouse plants that fill there pots with
roots. |
 |
Lift early potatoes, there is nothing quite like the
taste of home grown early potatoes. |
 |
Sow the seed of herbaceous perennials and biennials out
of doors this month in a prepared seed bed. |
 |
You can still direct sow hardy annuals where they are
to flower in late summer, support with twigs hardy annuals as required.
|
My tips for the month
 |
Summer is not far away, it may be necessary to make
good any rainfall deficit to maximize good plant growth. |
 |
Topiary or the art of shaping trees and shrubs by
clipping and wiring is a wonderful way of creating all year round interest
in garden. Clipping will be frequently required to keep the looking neat and
tidy. |
 |
Frost should not be a problem but when both March and
April have been very dry months there is a risk of a frost in early May. |
 |
Keep on top of weeds by hoeing, never let them get to
large or flower, always remove the roots of perennial weeds. |
 |
Watch out for Vine Weevil damage in container plants,
grubs hatch in spring and eat the roots of an increasing range of plants,
plants will wilt, remove the creamy white grubs after taking the plants out
of there pots. The adult dark grey beetles do little damage other than take
notches out of leaves but as they are nocturnal they are difficult to
control. |
 |
Lawn mowings scattered between the rows of carrots can
reduce the effect of carrot fly. |
 |
Centipedes eat insect pests like grubs, slugs and
woodlice so don't kill them, unlike millepedes which chew plants and should
be controled. |
