What to do in the garden in September

September is the time to prepare for autumn gardening tasks.  The weather can be changeable this month, from mild warm days to wet and chilly.  There are lots of tasks to keep you busy in the garden in September.

The beginning of autumn is a good time to create new lawns and improve damaged ones.  Sow seeds or lay down new turf to repair damaged areas.  Brown, dry patches damaged by the sun will begin to repair with cooler weather and rain.  Now is a good time to scarify and aerate lawns to improve air flow and apply top dressing to create a healthy lawn.

Beds and Borders

In beds and borders, tidy up fallen leaves and spent vegetation.  Pruning roses, dahlias and late-summer flowering shrubs to extend their performance.  Dividing up herbaceous perennials to keep them healthy and encourage more growth.  Planting out chrysanthemums now will fill the garden with colour until the end of the season.  Spring flowering bulbs such as daffodils, hyacinths and crocus can be planted out now ready for a burst of colour next spring.

Vegetable Garden in September

As harvest time approaches there is a lot to do in the vegetable garden in September.  Crops are plentiful at this time of year, keeping you busy picking beans, corn, tomatoes, cucumbers, carrots and courgettes. Harvest apples, pears and plums.  Pick blackberries, raspberries and pot up strawberry runners for the yield next year. Now is a great time to collect seeds from your flowers and crops and taking cuttings from gooseberries and currants ready for next year.  Lettuce and spinach can be planted at this time of year along with spring cabbages.

The weather is still ideal in September to get out and give trees and hedges a final prune and trim before winter.  Remember to leave some vegetation and seeds in the garden to provide food and shelter for the wildlife. Leaving seed heads on sunflowers and hips on roses will give the resident birds a hearty feast in the build up to winter.    A small wildflower meadow patch with long grass and a wood pile can create a great winter habitat for beetles, grubs and small animals like hedgehogs.
