Cut back tall perennials before the first frost. Chopping down to a few inches above the soil seems brutal, but it does no harm and allows for spring's resurgence.
Drain the hose and bring it in for winter. Wipe down with a rag, so there's no mud or moisture on it. Store it flat, letting it coil naturally, someplace dry and dark.
Close the compost pile for the winter. Its activity has been slowing for a while, and adding kitchen scraps to it now only leads to a pile of frozen garbage. Give it one last stir, and then replace the lid or cover it with a tarp.
