September gardening tasks

  • September gardening tasks

September is a great month to take stock of the successes and failures this year and put in place plans for better results next year. The soil is still warm, rainfall usually increases. Work done now will both get your garden in order and pay dividends next spring.

September is a good time to:

Sow grass seed
Make divisions of herbaceous perennials and water these well
Clear and wash down greenhouse with mild disinfectant to deter pests and diseases and maximise winter light
Clip hedges for last time this season
Take stem cuttings and prune climbing/rambling roses, once flowering finished
Pick fruit as it ripens e.g. apples, plums, autumn raspberries
Clear away dying annuals
Collect and sow seed from perennials and hardier annuals
Divide and plant bulbs for garden and indoors e.g. daffodils, crocus, hyacinth, amaryllis
Clear away crops that have finished producing e.g. cabbages, peas
Harvest last crops that may be at risk from slug damage or frost e.g. potatoes, marrow, squash
Cut down asparagus foliage
Sow parsley for next spring
Plant new perennials as soil still warm and there is generally now more rainfall
Order new trees and shrubs, which will grow faster next spring if put in this autumn
