Always use sharp, clean secateurs to avoid injuring plants or introducing disease. The timing depends on the type of climber. Prune repeat bloomers in spring, the same time you cut out dead, crowded or crossing branches. Prune roses that bloom once a season after their blooms fade. Many climbers bloom on second-year wood, so don t sheer plants off.
Some gardeners remove one older cane per year to let younger, more vigorous canes develop.
