Things are starting to slow down in the garden - but we can still give you lots of jobs to do!
- Keep deadheading annuals, perennials, and roses to keep the flowers coming and hanging baskets as they will flower till the first frosts with a bit of TLC.
- Collect and sow seed from hardy annuals and perennials
- Fill gaps in borders with autumn flowering plants like sedum and chrysanthemums
- As the weather cools herbaceous perennials can be divided to make new plants
- Plant hyacinth and amaryllis bulbs for forcing so that you have colourful blooms at Christmas.
- Start to plant spring flowering bulbs such as daffodils, crocus, Scilla and hyacinths and Aconites and Snowdrops for January/February
- Buy or plant out biennial plants sown earlier this year i.e. foxgloves, wallflowers, and Violas.
- Plant new perennials of your choice while the ground is still warm.
- Start to consider choice of any new trees, shrubs, bare root roses and hedges for planting in autumn/winter
- Prune late summer flowering shrubs like Helianthemums.
- Sow sweet peas in a cold frame or unheated greenhouse for planting out in spring
- Prune climbing and rambling roses once they finish flowering (not repeat flowering ones)
- Trim box, Euonymus, and Privet hedges if needed before they go dormant
In the vegetable garden
- Raspberries, blackberries and other autumn fruiting varieties will soon be ready for picking so make sure the birds don’t get there first by netting them
- Keep harvesting crops and if you have a lot of fruit and veg then freeze, dry or pickle them.
- Keep feeding and watering French and runner beans to prevent them setting seed.
- Plant second crop seed potatoes for new potatoes at Christmas
- Plant of an over-wintering variety from the middle of the month.
- Pull or cut off the foliage of main crop potatoes at ground level 3 weeks before lifting to prevent blight spores infecting the tubers as you lift them.
- For a supply of herbs during the winter, pot up plants of basil, marjoram, mint, oregano, and parsley and grow them on the kitchen windowsill.
- Transplant spring cabbage into their final position.
- Early September is an ideal time to sow a new lawn or repair an existing one. Keep the lawn clear of fallen leaves and treat any moss, scarify and aerate. Overseed with something like Johnsons General Purpose Grass Seed and add a top dressing of Westland Lawn Dressing then apply a product like Evergreen Autumn that will help fertilise as well as killing moss.
- Rake up fallen apples and compost before they attract wasps
- Net ponds before leaf fall gets underway.
- Clean out cold frames and greenhouses so they’re ready for autumn use
