September Gardening Tasks

taking pelargonium cuttings

There is still time during September to take semi-ripe cuttings of shrubs and some tender perennials ready for over-wintering in the greenhouse. Use vigorous shoots from this seasons growth as cutting material. See our easy step by step guide for instructions on taking semi-ripe cuttings.

Now that autumn is well on its way (autumn usually starts in the UK on 21st of September), there is little to do in the garden apart from tidying-up plants and flowers that have finished flowering. As well as continuing to watering containers and hanging baskets, don't forget to keep watering any early flowering shrubs, especially azaleas, camellias and rhododendrons, to encourage next year's buds to form. If early flowering shrubs are allowed to dry-out then these precious buds are likely to drop off.

Take time this month to clean-up the greenhouse. Tidy-up and remove dead leaves and debris that might harbour over-wintering pests and give the greenhouse a thorough clean. Remove any shading from the glass and check that greenhouse heaters are in working order before the frosts arrive.
