Troubleshooting
Salal problems — and how to fix them
Salal (Gaultheria shallon) is generally low-drama, but a few issues come up again and again. Here is what each one looks like, why it happens, and the fix.
Invasive spreading via rhizomes
In moist, shaded conditions salal can spread aggressively and outcompete other plants. Install a buried root barrier or remove unwanted suckers each spring to keep growth in bounds.
Leaf spot in poor airflow
Fungal leaf-spot diseases can develop in very dense plantings with limited air circulation and high humidity. Prune out congested stems and avoid overhead irrigation.
