FAQ: Is it too late to plant perennials in zone 6?

Q. I live in USDA climate zone 6. Is it too late to plant perennials?

A. It is not too late (end of September) to plant cold-hardy perennials in zone 6, particularly if they are container grown. Plants that have been produced in a greenhouse may not become hardened-off before first frost, so you could see some tissue damage. But it would probably be only cosmetic. An insulating layer of organic mulch around the plant should be helpful.
