How to Prune Old-Fashioned Roses
Old-fashioned roses such as albas, mosses and damasks are pruned lightly in summer after the first flush of flowers.
Step 1: Trim Stems
Remove any wood that is dead and diseased, then cut back the main stems and sideshoots by one-third to a healthy, outward facing bud.
Step 2: Minimize for Strength
When fall arrives, cut back any extra-long whippy stems that could be vulnerable to damage by strong winter winds.
Step 3: Prune Gallica Roses to Main Stem
Gallica roses are pruned in much the same way as other old-fashioned roses, but cut the sideshoots back to the main stem, or to a shoot close to the main stem.
