Fall Pruning Guide: Rose of Sharon, Endless Summer Hydrangea, and Roses

Species-Specific Pruning Timing

A Wisconsin gardener asks about fall pruning for rose of sharon, Endless Summer hydrangea (after freeze), and old rose blossoms.

Endless Summer hydrangea: DO NOT PRUNE NOW – Removes next year's flower buds. Protect with burlap instead.
Roses: PRUNE TO GROUND – Bloom on new wood; severe pruning stimulates best regrowth.
Rose of Sharon (Hibiscus): PRUNE NOW ACCEPTABLE – Also blooms on new wood; no flower loss.

Understanding bloom wood type (old vs. new) determines safe pruning windows.
