Rose pruning in Southern California.
Our climate here is mild; roses can go year-round. Pruning for optimum
appearance, blooms, and growth are typically done in January.
They, like anything, do better with a ‘rest’; the pruning accomplishes this.
Helpful tips, do not prune too harshly, cut one-third, on older established bushes. Do not prune prior to rain, water inside newly cut canes will cause damage. Striping the leaves from the plant will also encourage ‘dormancy/rest’.
Iceberg roses are the most forgiving of any bad pruning attempts, many are actually pruned down with gas hedge trimmers.
