In May, Nick and Sue get busy in the garden, greenhouse and allotment sowing, planting, pruning and preparing the soil

Week 1
BULBS: Deadhead any early spring-flowering bulbs.
CANNAS: Split and repot canna lilies if the pots they are in are too small.
DAHLIAS: Start watering dahlias in the heated greenhouse to encourage new growth that can be used for cuttings.
HERBACEOUS PERENNIALS: Divide large clumps if needed, then replant smaller pieces.
SELF-SEEDED PLANTS: Dig up any self-set seedlings growing in the wrong place and replant carefully in better positions. Water them in well – don't allow them to dry out, as the roots will take a few weeks to establish.
Week 2
BULBS: Identify and label any bulbs in flower, if not already known. We plant out lilies in some areas of the garden.
EVERGREEN SHRUBS: Dig up any growing in the wrong place and move them.
SNOWDROPS: Lift, divide and replant overgrown clumps of snowdrops 'in the green', which means after they finish flowering, but before the leaves die back.
LAWNS: For your annual lawn maintenance, now's the time to scarify, aerate, top-dress, feed, and seed or turf any bare patches.
Week 3
CHICKEN MANURE: Apply pelleted chicken manure to all beds and borders to give plants a feed.
DAFFODILS: Start deadheading daffodils regularly.

PRUNING: We prune the following plants:
Artemisia,
Buddleja,
Caryopteris,
Cornus,
Cotinus,
Erica,
Forsythia,
Fuschia,
Garrya, grasses,
Hydrangea,
Hypericum,
Jasminum nudiflorum, Lavender,
Lonicera purpusii,
Mahonia,
Penstemon, Roses,
Salix,
Sambucus,
Santolina,
Spiraea japonica,
Vinca.
LAWNS: We give our lawns their first cut of the year.
PONDS: Take off any nets protecting ponds from falling leaves (unless you have trouble with herons taking your fish). In spring you can top up ponds and water features if they need it, and return pumps to the water.
SEED SOWING: Sow your choice of various annuals and perennials.
Week 4
FUCHSIAS AND PELARGONIUMS: Cut these back in spring to provide bushier plants. Any suitable material you have left over can be used as cuttings and propagated.
PLANT SUPPORTS: Place these around the garden where tall-growing plants are. They will provide extra support to tall stems later in the season. Put up canes or obelisks in readiness for climbing annuals.
TENDER PLANTS: Repot these if they are becoming pot-bound, and top-dress other potted plants to give them a smarter appearance.
WATERING: Depending on the weather, water plants as and when needed. Water plants in containers as the weather warms up – even when it rains, a pot is unlikely to get a good soak.
Greenhouse
|
| When pricking out seedlings, hold them gently by a leaf, never the delicate stem

CELERY: Pot on into 8cm (3in) pots.
CUCUMBER: We sow cucumber 'Bella' into 8cm (3in) pots.

POTATOES: Harvest the remainder of the first earlies from large pots.

PRICK OUT: Prick out seedlings, including celeriac, so they can grow on into plants. Put them in modules or 7cm (3in) pots filled with peat-free compost. Take care when pricking out – hold the seedlings by the leaves, but don't touch the delicate stems.
