What to do in the garden:

September by Tom Petherick

As the days begin to shorten and night time temperatures drop a different feel to all matters horticultural comes into being. it is time to start working on the soil once again, mulching after rain, digging over areas with a perennial weed problem or that need rearrangement for next year. It is often one of the most pleasant months for gardening particularly as there is so much promise in the ordering, buying and planting of new trees and shrubs whether ornamental or fruiting.

LAWNS
Very much the month to star work on the lawn after what are usually the two driest months of the summer in July and August.Aerating with a fork and adding sharp sand or compost will encourage new growth as will scarifying with a rake and removing the thatch.

BEDS AND BORDERS
Beds and borders. Keep deadheading and removing old flowered growth. Dahlias should be at their very best through September and should be carefully looked at daily. Pick the flowers regularly, water as required and keep tying in, heavy rain and wind could take its toll on plants that are well grown.

GREENHOUSE
Bring plants that have summered outside in such as jasmines, clivias and orchids, start to feed and top dress with some fresh compost. Make sure to close the doors and bents at night but if doing this the greenhouse must be ventilated on sunny days. keep damping down against red spider mite.
