Never Cut Back These 7 Perennials in Fall (Japanese Gardens Leave Them Until March)

If your October Saturday goes to cutting the whole bed down, and your May goes to finding out what didn't come back: https://thesmallgardenbook.com It sorts every plant on your lot into tenants and hires, and puts the garden year on one card, so March finally gets its date. 379 pages, 88 chapters, every claim sourced. $47 early-bird, 30-day refund. I grew up in a Japanese house. I've now lived in America longer than I lived in Japan. Everyone tells you a clean fall bed is good gardening. For a lot of perennials the brown part is still on duty. The stems, the blades and the leaves are doing a winter job, and the shears take it away. This walks through seven perennials you'll find in most American beds, in three groups: the ones a fall cut can kill, the ones whose stems are a home, and the ones whose leaves are their winter coat. For each one, what it looks like right now, what the cut actually does, and the week to cut instead. And at the end, the word my mother had for the brown row along her fence. The other side, said plainly: a tidy October bed is a real pleasure, and mildewed phlox and bee balm, peony foliage, bearded iris leaves and mushy hosta should come down now and go in the trash, not the compost. This is written for zones 4 to 8. In zone 9 and along the Gulf most of the winter damage never happens and you can tidy in December, and in wildfire country, cut your ornamental grasses in fall. One plant warning: Miscanthus, sold as maiden grass or zebra grass, is on invasive lists in Pennsylvania, Virginia, Kentucky, Tennessee, Georgia, Massachusetts and Connecticut, among others. Switchgrass gives you the same winter picture and stays put. If you make it to the end, leave one word in the comments: done. And tell me which of the seven you've been cutting every fall, and what zone you're in.
