Troubleshooting
Buddleja 'Miss Ruby' problems — and how to fix them
Buddleja 'Miss Ruby' (Buddleja davidii 'Miss Ruby') 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.
Leggy growth without pruning
Stems become bare and top-heavy if not cut back. Hard-prune to a low framework in early spring each year.
Spider mite and capsid bug
Bronzed, webbed leaves in hot dry spells or distorted shoot tips. Monitor new growth and hose down foliage in droughts.
Dull colour in shade
Insufficient sun mutes the ruby tone and reduces flowering. Plant in full sun for the best display.
Root rot in wet soil
Heavy or waterlogged ground rots the roots over winter. Use free-draining soil and avoid low, soggy spots.
