Should I shape prune roses in the fall?Updated a month ago

Deciding when, how, and how much to prune can be overwhelming, but it’s simpler than it seems. I recommend pruning three times a year: first, deep dormant pruning in winter; then, light shaping in summer; and finally, light shaping again in the fall.

When pruning David Austin English shrub roses, as well as hybrid teas, floribundas, and grandifloras, keep a few key points in mind before winter. Lightly prune to reduce height and prevent the canes from whipping in winter winds, but avoid heavy pruning in the fall. Stick to removing about a third of the cane length to maintain structure. A good rule of thumb is to prune to shoulder or waist height. Think of shape pruning like a little bang trim rather than a full haircut.

Heavy pruning can encourage new growth, which is vulnerable to cold damage. Light pruning won’t signal the plant to produce new growth, helping prevent wind damage and breakage. Save more significant pruning for late winter or early spring, just before new growth begins, allowing time to assess winter damage and prepare for a fresh growing season.

Old Garden Roses, like Madame Hardy, are more forgiving and can thrive with minimal fall pruning. Similar to English shrub roses, you can slightly reduce cane length, especially if they’re tall, to prevent winter damage. Save significant pruning for late winter during dormancy or early spring, as these roses often bloom on old wood. Be cautious with fall pruning and only tackle the most unruly canes.

In summary, light pruning on all types of roses (no more than a third of the cane) is fine now to reduce height and protect the plant from winter wind. Reserve heavy pruning for late winter or early spring, depending on your growing zone, to keep them healthy without triggering vulnerable new growth too early.
