Troubleshooting
Ceanothus americanus problems — and how to fix them
Ceanothus americanus (Ceanothus americanus) 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.
Root rot in wet soil
Heavy or poorly drained ground causes rot and decline. Plant only in sharply drained sites and never overwater.
Transplant resentment
The deep taproot dislikes disturbance, so older plants move badly. Establish young, container-grown stock in its final position.
Sparse flowering in shade
Too little sun or over-rich soil yields leafy growth and few blooms. Site in full sun on lean ground.
Powdery mildew
Can appear in humid, crowded conditions late in the season. Allow good airflow and avoid overhead watering.
