The Garden in September

The Garden in September

September is often blessed with warm days, even an Indian summers but can be accompanied with cold clear nights. Autumn is just around the corner and rain can be very much a feature of this time of year.

If there are gaps in the garden there is still plenty of colour available in the outdoor plant sales area of the centres, including the reds and yellows of rudbeckias, Echinacea and helenium as well as a wide range of Michaelmas daisies (Aster Nova Belgii). However do be aware that these late bloomers can be susceptible to powdery mildew. If so there are several remedies for this including Fungus Clear Ultra.

Now’s the time to think about planting trees and shrubs. The soil is both moist and warm which is ideal to help establish plants. They will make lots of root now so that by the time next spring comes they will grow away well. They also won’t suffer as much if the following year turns out to be dry either.

Bulbs are now also available. The range is huge so don’t be afraid to ask for advice. Some bulbs such as daffodils, chionodoxa, snowdrop, winter aconite, crocus and anemone blanda appreciate being planted in September. Don’t forget that bulbs such as daffodils and crocus can be planted in grassed areas to give dull lawn areas a splash of colour in the spring.

Winter flowering pansies will be on sale too – if they are planted early they will tend to flower through the autumn and into the winter. Later plantings tend not to flower until late winter early spring. However watch that if the weather does turn hot that they don’t get too drawn, to stop this happening reduce the amount of water you give them as this will help to keep the pansy plants compact.

Here are some more tips on what to do in the garden this month
• Lift onions and dry on rack.
• Continue to harvest vegetables such as peas and runner beans.
• Harvest first apples and pears if ready.
• Propagate new strawberry plants by selecting runners.
• Continue to tie in and support tomato plants, peppers, cucumbers, aubergines and melons as they develop, especially as fruit starts to swell or they will quickly topple over and be damaged
• Water and feed tomatoes.
• Protect salad plants from slugs and snails.
• Keep feeding your container plants,
• Prune late summer flowering shrubs after flowering.
• Prune Wisteria now to encourage the development of new flowering spurs for next year’s display of flowers.
• Keep an eye on any new plants in the garden and be sure to water them if the weather is dry.
