The flower garden
Divide perennials that flower before midsummer’s day, such as oriental poppies, peonies and lupins, as well as spring-flowering hellebores, pulmonarias and Solomon’s seal. Dig up, divide and replant straight away. Perennials that flower after midsummer are best divided in the spring – that’s a good general rule.
Add several inches of mushroom compost to your dahlia beds, or lift and store for the winter.
Plant the last of your autumn bulbs, eg tulips. Don't forget to put some in pots as well as in the garden.
The veg patch
SContinue to plant garlic, as it likes a period of dormancy and cold prior to growing away in the spring.
Sow boxes of cut-and-come-again salads and hardy herbs for putting right outside your kitchen door.
Summer-fruiting raspberries and blackberries need cutting back, tying in etc. Leave autumn-fruiting raspberries until later in the winter.
Green gardening
Start sowing sweet peas for next year – overwinter under cover.
Remove the last of the fallen leaves from around the base of plants to prevent slugs/snails overwintering.
