Anyway, cut back the straggly perennials and scratch a little compost into the soil around them. After dahlia and tuberous begonia foliage dies back, dig up the tubers. Clean and store them in a cool, frost-free place out of the direct sun. To keep the roses blooming, trim off spent flowers, cutting down to a five-leaflet leaf. Don't prune anything yet.
Wounds heal slowly now.
Wait until later in the dormant season. Cuttings should be made of pelargoniums, fuchsias and hydrangeas. In the case of the first two, this is a safety measure, because every so often a severe freeze wipes out your favorites. Be on guard for a resurgence of slugs and snails in cool October weather. Hand pick them or put out bait.
