Now is a good time to divide perennials, but remember to keep any transplanted or new plants well watered.
DAYLILIES can be dug and divided as they complete their bloom cycle, right into fall, if needed.
PEONIES are best divided and transplanted in late August through September, if they need it. Remember with these fussy guys that “eyes” must not be buried more than an inch or two beneath the soil surface.
DON’T DEADHEAD FADED perennials, biennials and annuals if you want to collect seed (non-hybrids only) or plan to let some self-sow. Nicotiana, annual poppies, larkspur, clary sage and many others fall into this leave-alone group. So do plants with showy or bird-friendly seedheads, like coneflowers, some sedums, clematis and grasses.
TREES & SHRUBS
BE SURE TO WATER trees and shrubs now through hard frost, so that they enter dormancy in a well-hydrated state. Evergreens (needled ones and broadleaf types like rhododendron, too) are particularly vulnerable to desiccation and winterburn if not well watered before the cold and winds set in.
DON’T PANIC IF EVERGREENS start to show some browning or yellowing of needles this month and next. The oldest, innermost needles typically shed after a few years on the tree.
HOPEFULLY YOU STOPPED FEEDING woody plants in July or August. Promoting more soft growth after July-ish isn’t good; time for them to start moving toward the hardening-off phase of their cycle. No more eats till earliest spring.
ALWAYS BE on the lookout for dead, damaged, diseased wood in trees and shrubs and prune them out as discovered. Ditto with suckers and water sprouts. No hard pruning after late August, though; too late to risk encouraging regrowth.
