That’s one fall garden chore you can postpone till next year.
And here’s another.
Don’t cut back your perennials and grasses either.
Beneficial insects use rough vegetation to either overwinter themselves or lay eggs to be hatched next spring. Those eggs will hatch before aphids and other pests appear. The adults from this first round of eggs will lay their eggs in time to control the aphids then later on thrips, spider mites etc.
By cutting back all that rough vegetation now you are essentially tossing nature’s army of beneficial insects into the trash and that’s a waste of their talent. This is all part of creating a “host environment” and I cover that more in depth in my book ‘Everyday Roses’ published by Taunton Press.
Try to resist the urge to cut back your garden in the fall. I know it’s nice to have it looking tidy during the winter but just think forward to next spring when possibly cutting it back now could result in an aphid infestation later. In my opinion that would be much worse!
