If last month was busy then this month should be even busier. May is usually the month when plants catch up from a slow, cold start and respond quickly to milder conditions. So, get sowing and planting. However, don't forget that late May frost can be the scourge of all gardeners.
Mow lawns once a
week reducing the blades to 2cm. Apply selective
weed killer and fertiliser or lawn sand if not
done last month. Bare patches can also be
over-seeded or turfed for the larger areas.
Support perennials with twiggy sticks or purpose-made plant supports. Clear spring bedding from borders and beds when flowers fade and add a general fertiliser to the soil. Allow bulb foliage to die back naturally; do not cut it down. This way you will ensure a bumper show next spring.
Once danger of frost has passed plant summer bedding. Thin out hardy annuals sown last month.

Spray roses against aphids and fungal diseases. Prevention is better than cure. If you want roses like this, then start early. The first feed should already have been applied!

Commence clipping hedges now that the first flush of growth has appeared. It may also be your last chance to treat your fences with a suitable preservative; but quickly before too much new plant growth hinders.
Plant out chrysanthemums and young dahlias when danger of frost has past. Protect emerging shoots from slugs and snails. -> -> -> ->

In the cold greenhouse peppers tomatoes aubergines melons and cucumbers can be planted in May. Ventilate on sunny days and damp down the floor, shade if necessary. Keep an eye on the watering and be prepared to water more often as the temperatures increase throughout the month. Feed tomatoes once a week when fruits have set with a high potash fertiliser.
