Troubleshooting
Buddleja globosa problems — and how to fix them
Buddleja globosa (Buddleja globosa) is generally forgiving once you match its basics, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Poor flowering after hard pruning
Unlike B. davidii, it blooms on old wood, so spring hard-pruning removes the flower buds. Prune only lightly after flowering.
Frost damage
In hard winters or cold gardens the semi-evergreen growth can be cut back by frost. Site in a sheltered, sunny spot and avoid late soft growth.
Legginess with age
Older plants become tall, bare and woody at the base. Renovate gradually by removing some of the oldest stems after flowering.
Capsid bugs and caterpillars
Occasional sap-sucking capsids or leaf-chewing caterpillars distort or hole the foliage. Tolerate light damage or pick off pests; the shrub usually grows away from it.
