You promote the joy of flowering and vitality with one Clearance cut at 2-year intervals. How to do it right:
- The best time is after the flowering period has ended
- Cut off a third of the oldest scaffolding shoots at floor level
- Cut back this year's growth on excessively long branches
- Incision a few millimeters above an alternate pair of leaves
By cleaning up withered inflorescences, you may be able to stimulate a sparaceous shrub to re-bloom slightly. Place the scissor blades 3 to 4 millimeters above a pair of leaves or a bud.
Perform rejuvenation pruning in winter
