Troubleshooting
Wood Sorrel problems — and how to fix them
Wood Sorrel (Oxalis acetosella) 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.
Leaf scorch in sun or dry conditions
Any direct sun exposure causes rapid leaf scorch and collapse. Ensure consistently deep shade and adequate soil moisture, especially during dry spells.
Spreading aggressively in ideal conditions
In moist, shaded beds it can spread vigorously via rhizomes. Easy to control by hand-pulling or containing with edging; treat as a ground cover in areas where spread is welcome.
Powdery mildew and rust
Fungal issues can occur in crowded or low-airflow conditions. Thin dense patches and avoid overhead watering.
