The momentum of work increases as
the season advances. Much depends on the weather,
for if the ground is saturated the tilth required
for sowing seeds cannot be obtained, and the soil
will be too cold for germination.
March is the time to...
sow seeds and grow young plants to create a real
splash this summer.
TREES AND SHRUBS
Complete planting of bare-rooted trees
Layer shoots of chimonanthus, cotinus, Magnolia
grandiflora and other shrubs that do not root
easily from cuttings, as spring growth starts.
Cut out flowering shoots of winter-flowering shrubs
such as Jasminum nudiflorum.
Cut back last year’s stems of salix and

Layer Vitis coignetiae, Pileostegia viburnoides
and other climbers.
Complete pruning of large-flowered clematis.
Complete planting of bare-rooted roses when ground
is neither frozen nor waterlogged.
Prune repeat-flowering climbers, shrub, bush and
Dress all plants with base fertiliser and rake
Plant perennials when soil conditions are favourable.
Divide clump-forming plants left over from autumn,
including less hardy types such as paeonies,
as soon as new growth begins.
Divide summer-flowering alpines such as Campanula
gramineus and Geranium
Plant nursery-raised plants for spring and summer
WATER AND BOG PLANTS
Remove dead and dying tops of marginal plants
left on for winter protection.
Put in all types of water plants for bog garden.
BULBS, CORMS AND TUBERS

coronaria cultivars for flowering in summer.
Remove fading flowers from daffodils,
other late winter-flowering plants, but leave
the foliage until it has died down.
Continue feeding bulbs with general fertiliser
as soon as the leaves start to appear.
ANNUALS AND BIENNIALS
Sow half-hardy annual seeds under glass. In mild
districts, sow hardy annual seeds outdoors.
Harden off earlier-sown half-hardy annual seedlings
in a cold frame. Protect frame against frost with,
for example, an old piece of carpet.
Plant out sweet
pea seedlings sown the previous autumn.
Rake over and reseed worn or bare patches.
Apply a spring/summer general fertiliser.
In a mild season, mow the grass as its growth
rate dictates, with blades set about 1 in high.
Complete all digging as soon as possible, removing
and burning perennial weeds.
Clear weeds from paths and drives.
Scrub stone paths and drives with a garden brush
