The timing and method of pruning roses can vary depending on the type of rose. Here are some general guidelines:
Hybrid Tea Roses and Floribunda Roses: Prune these roses in late winter or early spring, around February or March. Remove any dead or diseased wood and cut back the main stems to about 6-8 inches from the ground. Also, thin out any overcrowded growth to promote good air circulation.
Climbing Roses: Prune once-flowering climbers right after they bloom, typically in late spring or early summer. For repeat-flowering climbers, prune them in late winter or early spring. Remove any dead or weak stems and cut back lateral shoots to encourage new growth.
Shrub Roses: Prune shrub roses in late winter or early spring, similar to hybrid teas and floribundas. Remove any dead or damaged wood and lightly shape the plant as needed.
Rambling Roses: Prune rambling roses after they finish flowering, usually in late summer. Remove old, woody stems and tie new, vigorous shoots to their support structure
