Troubleshooting
Mahonia Charity problems — and how to fix them
Mahonia Charity (Mahonia x media 'Charity') 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.
Legginess with age
Tends to grow tall and bare-stemmed; prune some stems hard after flowering to promote denser lower growth.
Mahonia rust
Orange-brown pustules on leaves in humid, congested conditions; remove affected foliage and improve ventilation.
Powdery mildew
White leaf coating when soil is dry and air humid; keep the root zone mulched and moist.
Sharp spines
The rigid spiny leaflets are a real handling and siting hazard rather than a disease; plan placement away from paths.
