What to do
Lay new turf now so the grass can settle during the winter. Dig over the ground, get rid of weeds and rake the tilth so the surface is even. Use a line to keep the turves straight and lay them so the joints are staggered. Sift soil into gaps and firm down the turves by banging them with a rake head.
Fill outside containers with plants for winter interest. Heathers such as white 'Lyonesse' and pink 'St Keverne' flower through the autumn. White 'Springwood' and pink 'King George' pick up the baton in December.
Moss growth accelerates as grass growth slows, so if you do not like it, treat moss now with a residual moss killer.
Divide and replant clumps of chive and mint.
Lift dahlia tubers after stems have been blackened by frost. Cut stems back to about 3cm/1in and leave them to dry for a week or so. Then dust them with a fungicide such as flowers of sulphur and pack them in boxes of damp compost or sand. Store them in a frost-free place.
