This time of year I typically get sick of looking at all the dead plants, and go to town with my shears. However I know I need to leave foliage for the birds and wildlife in winter.
I cut my plants back about a month ago. But it’s cooling off now, just a bit, and most of the ones I’d like to have grow back are going strong.
Particularly the containers of ornamental grasses. They have grown at least a foot!
Trimming back the leaves at the right time keeps the plant healthy and attractive, while still allowing the iris to replenish the nutrient stores in its rhizomatous root system.
It is best to cut back bee balm because it has a tendency to mildew
Phlox: It also has a tendency to mildew.
Prune the daylilies. If you don’t prune daylilies, you will get new growth mixed in with old come spring.
Once the green leaves start to die, take off the foliage.
Blanket Flower: Cut this plant back in the fall because it helps the plant to come back more vigorous come spring/summer.
