Troubleshooting
Chandler Strawberry problems — and how to fix them
Chandler Strawberry (Fragaria × ananassa 'Chandler') 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.
Angular leaf spot (Xanthomonas fragariae)
Water-soaked, angular spots on leaf undersides turn red-brown on upper surfaces. Spread by overhead irrigation and rain splash. Use drip irrigation, improve airflow, and avoid working among wet plants. No effective chemical cure; remove heavily infected leaves.
Botrytis fruit rot
Grey, fuzzy mould on ripe fruit in cool, wet conditions. Chandler's large berry size means fruit sits close to the soil — straw mulch and prompt harvesting every 1–2 days during peak season reduces losses. Remove and destroy infected berries.
Spider mites
Fine webbing on leaf undersides with stippled, bronzed leaves in hot, dry spells. Knock back with a strong water spray; introduce predatory mites (Phytoseiulus persimilis) in polytunnels. Avoid broad-spectrum pesticides that kill natural predators.
