What to know about pruning in autumn
A clear overview of what not to prune now, what the last pre-frost trims are, and what can wait until spring — with links to species guides.
Fall pruning guide
What to cut now, what to leave standing, and when frost arrives where you live.
Open guideWhat not to prune
Spring-flowering shrubs on old wood, mophead hydrangeas, and frost-tender trims. Deadhead only; leave structure standing.
Open hubLast trim before frost
Lavender, rosemary, heleniums and a final light hedge trim — only on a dry, frost-free day.
Open hubWhat can wait
Most of the shaping work. Leave hydrangeas, early-flowering shrubs, clematis groups that bloom before midsummer, and most grasses and seedheads until late winter or spring.
