When to Prune Roses
When to prune roses. How to determine the best time to prune roses. Optimal time to prune rose bush plants. When to prune rose bushes. When to prune climbing roses. When to prune Knockout roses.
These gardeners have a valid point.
But as cutting back any tender plant in the fall makes me nervous, I think spring is generally the best time to prune roses. Do this as soon as the weather warms and before the roses swing into full growth.
The fewer leaves clinging to the stems, the easier it will be to see where to make your cuts when
Winter Pruning Roses
If you live in a cold winter area where roses require special winter protection, winter rose pruning may be in order.
This is done in late fall, before the first frost.
Another situation in which pruning roses for winter may be necessary is in very windy areas. A tall Hybrid Tea or climbing rose may topple due to wind-rock unless the longest shoots are cut back.
If you winter prune roses, check the stems over carefully in the spring after the winter protection is removed. Trim away any that have been frost damaged.
Pruning Your Roses for Best Bloom
This is the final, and perhaps most important, thing to consider when deciding when to prune roses.
If your rose blooms only once a year, in the spring, (some of the old climbers and rambling roses fall into this category) prune it just after the flowers fade. Otherwise, you will lose many, if not all, of this year's flowers.
Roses that bloom repeatedly throughout the growing season can safely be pruned in the spring.

When to Prune Roses in the South
In mild winter areas, roses can be pruned at any time of year. And they may need to be pruned more often to control their exuberant growth.
In my zone 9a garden, I prune rose bushes in the spring and again in late summer or early fall if the shrubs have gotten way too big.
I do the heavy pruning in the spring and a light trimming in the fall just to neaten the plants.
