How to prune buddleja globosa

Immediately after flowering, typically late June. Deadhead spent orange flower balls and trim back flowered shoots by up to one-third to a strong side branch. Remove any dead, diseased or crossing stems. If rejuvenation is needed, stagger hard cuts over two or three seasons rather than cutting all old wood at once.

Annually (light trim); rejuvenation every 5–7 years if needed. Orange ball tree (Buddleja globosa) differs from common buddleja: it blooms on the previous year's wood, so do NOT cut it back hard each spring as you would with B. davidii. Instead, prune lightly after flowering, removing spent flowerheads and any dead or crossing branches. Hard renovation, if needed, is best spread over two to three years.
