As autumn settles in, gardeners are advised to focus on key tasks to maintain healthy plants and prepare their gardens for the colder months. One of the primary concerns during this damp season is the prevention of grey mould, which thrives in moist conditions. Gardeners should inspect plants regularly and promptly remove any affected leaves, flowers, or stems to limit the spread of spores. Ensuring good airflow by avoiding overcrowded planting and clearing away diseased material is also recommended.

After harvesting cranberries, attention should turn to managing the plants' appearance. Rather than heavy pruning, gardeners are encouraged to trim any untidy growth selectively to keep the low, spreading plants compact and manageable. This approach helps maintain the plants’ structure after fruiting without causing unnecessary stress.

Supporting structures such as stakes, hoops, and supports used for herbaceous plants can be removed once the plants have died back for the season. While these supports should be cleaned and stored in a dry place for reuse next year, gardeners are advised to leave attractive seedheads and sturdy stems standing as they provide winter interest and habitat for wildlife.

Autumn is also considered an optimal time for sowing cowslip (Primula veris) seeds. These seeds require exposure to winter cold to break dormancy and are best sown in trays or pots placed outdoors in a sheltered spot, such as a cold frame. Protecting the seeds from heavy rain and disturbance during the winter months encourages germination to begin in spring.

Lastly, a thorough inspection of wooden compost bins before winter is vital to ensure they remain functional. Gardeners should replace any rotten boards and secure loose or broken parts while the weather remains mild. Maintaining a sturdy structure helps keep compost contained while allowing adequate airflow, enhancing the decomposition process throughout the colder season.
