Pruning Guide
Pruning depends on rose class, climate, and whether the rose blooms once or repeats. When in doubt, remove dead, damaged, diseased, and crossing growth first, then prune lightly until you know how that rose behaves.
Basic rules
- Use sharp bypass pruners for most canes and loppers or a pruning saw for thick old wood.
- Remove dead, damaged, diseased, weak, crossing, or inward-growing canes.
- Keep the centre open enough for air movement and light.
- Cut to healthy tissue. If cane centres are brown or dead, keep cutting lower until the centre is clean or remove the cane.
- Clean tools between suspicious disease cuts.
- Dispose of diseased material instead of composting it.
Timing
- Many repeat-blooming shrub, floribunda, grandiflora, and hybrid tea roses are pruned in late winter or early spring as buds begin to swell.
- Once-blooming old garden roses and many ramblers bloom on old wood, so heavy pruning before bloom can remove the season's flowers. Shape them after bloom.
- Climbers are usually trained by tying main canes horizontally or diagonally and pruning side shoots for bloom production.
- In cold climates, winter injury may decide how far back the plant must be cut.
Cut placement and aftercare
- Make clean cuts just above an outward-facing bud when shaping.
- Remove suckers from below the graft union when they are truly rootstock growth.
- Some extension guidance notes cane borers may enter fresh cut ends; local practice may include sealing large vulnerable cuts.
- After pruning, water appropriately, refresh mulch, and avoid pushing tender growth too early in freeze-prone areas.
