Tips for gardening in autumn:

Build soil health:  Autumn is a good time to enrich your soil with organic matter so it’s ready for new planting. Spread a layer of compost on the surface before planting seeds or seedlings - there’s no need to dig it in, the worms and other invertebrates in your garden will do that work for you. For large, healthy blooms add some aged animal manure or slow-release fertiliser to feed your plants through winter.

Save seeds of summer annuals: Seeds of dahlias, cosmos, asters and other summer annuals can be saved once flowers have faded. Pinch off flower heads and dry them on a paper towel indoors for a week to ensure they are fully dry. Remove any remaining petals and place the dried flower heads in a paper bag for storage. Even if not saving seeds, leave some stems and seed heads of flowers in situ to provide food and nesting material for birds and insects.

Prepare for spring flowers: It may seem too early to be thinking about spring, but autumn is the best season to plant spring flowering bulbs such as daffodils, anemone, ranunculus and tulips. In warm climates, wait until late autumn when the soil has cooled for healthier and larger flowers. 

Hardy annuals and biennial flowers, including Canterbury bells and Honesty, should also be started in autumn so plants are large and mature enough to flower in early spring. The seedlings of these plants can sometimes look a little ragged by the end of winter, but their roots are spreading through the soil ready to support strong growth in spring. 

Pests and diseases to look out for in autumn:

Grey mould: Botrytis is a fungal disease that causes flowers to become mouldy and soft fruit such as strawberries to rot. Spores are transported by wind and can survive in soil or on green waste. The fungus spreads most in humid, cool weather.

To avoid problems with grey mould, water plants at soil level (not on leaves) in the morning, so leaves are not wet overnight. For plants affected by grey mould, prune off affected flowers and fruit and dispose of prunings to the compost bin or green waste bin. If necessary, spray with an appropriate fungicide or with neem oil. 

Powdery mildew: Caused by fungal spores reproducing on the leaves of plants, powdery mildew first looks like white spots on leaves, but affected areas can spread quickly to cover the entire leaf surface with a white powdery coating. While rarely fatal, powdery mildew can reduce yields. Water plants at soil level (not on the leaves) to prevent spores splashing from plant to plant, allow good air flow between plants, remove affected leaves and if necessary spray with an appropriate fungicide or homemade spray. 

Bi-carb of soda, also known as baking soda or sodium bicarbonate, is known to be effective at reducing powdery mildew and several other common fungus problems without posing the toxic risks of other treatments. Simply dissolve a teaspoon of the powder into one litre of ordinary water and add a few drops of liquid soap to help the mixture stick to the leaves. Pour the mixture into a regular garden sprayer or mister, shake it thoroughly, and spray liberally over the affected plants.
