Flowers
Autumn-flowering bulbs, such as autumn crocuses, Colchicum, Sternbergia, Amaryllis and Nerine, can be planted now.
Divide spring-flowering plants such as Irises now or during the next two months.Take cuttings of patio and container plants ready for next year. Last chance to sow biennials for next year – Sweet William, Wallflowers and Foxgloves.
Pinks and carnations that have become leggy can be propagated by layering or by cuttings. Propagation can improve the appearance of untidy clumps.
Prop up tall perennials such as lupins, delphiniums and gladioli if staking was neglected earlier in the season.
Liquid feed containerised plants and keep well-watered in dry spells.
Some late-flowering border perennials may benefit from a quick-acting feed before they come into bloom, especially if the soil is not very fertile.
Agapanthus thrive in sunny spots and free-draining soil where they won’t be overshadowed by taller plants.
Start collecting seed from plants you want to grow next year, especially annuals such as Calendula, poppies and love-in-a-mist.
Inspect lilies for the scarlet lily beetle whose larvae can strip plants in days. Pick off any you spot by hand.
In dry weather a silvery white coating may appear on the leaves of plants such as clematis, roses and Lonicera, caused by the fungus powdery mildew. Although it’s unsightly, it’s not usually harmful to plants.
