Should I cut down perennials end of season?

Cut down, otherwise you have a mess in spring. Don't pull them out. Most perennials seed in the fall, drop the seed so they can spread and create more plants.

Hello fellow Michigander! I cut mine down in the Fall as it saves a much bigger mess in the Spring. Happy Fall.

depends on the plant -- some bloom on old growth, some on new growth and some reseed ... Personally I don't cut mine back --- I don't mind the textures and colors that the bare plants provide in the fall -- better than a bare plot of soil --- just mulch well

If leaves dead, whack ‘em! If anything is still green, best to wait - the roots get their food from the leaves. My hostas are the only things that stay green so I just deal with them in spring. I just learned after YEARS of gardening that mulching in fall is sooo much easier than in spring. Don’t have to worry about getting around all that new growth.

And there are many more gardens at my house like these.

i mulch when everything has died back. It can be pretty chilly by the time I do it - early November- but much easier than in spring.
