Pruning depends on rose class, climate, and whether the rose blooms once or repeats. When unsure, remove dead, damaged, diseased, and crossing growth first, then prune lightly until the rose's flowering habit is clear.

* Many repeat-blooming hybrid teas, floribundas, grandifloras, and shrub roses are pruned in late winter or early spring as buds swell.

* Once-blooming old garden roses and many ramblers bloom on older wood, so heavy pruning before bloom can remove the season's flowers. Shape them after bloom.

* Climbers are trained by keeping main canes as horizontal or diagonal as practical, then pruning side shoots.

* Make clean cuts just above outward-facing buds when shaping an open plant.

* Remove true rootstock suckers from below the graft union at their origin, not just at soil level.

* For dense disease-prone roses, open the centre enough for light and air movement.

* After pruning, refresh mulch, water appropriately, and avoid forcing tender growth too early in freeze-prone areas.

=== US and UK notes ===

* US extension timing varies by region. Local county extension timing is better than a fixed calendar date.

* RHS groups pruning by rose type. UK growers should separate hybrid tea/floribunda, shrub, climber, rambler, patio, and groundcover guidance.
