How to spot it
Gray mold is a weak parasite that attacks wherever it is wet and cramped. On ripe strawberries, tomatoes or lettuce heads a typical gray‑fuzzy lawn forms, the fruits rot soft. Young plants can also collapse from it.
Prevention
Ensure airflow: wide spacing, exposed stock and dry leaves. Harvest ripe fruit promptly, remove rotting ones immediately and avoid injuries. In a greenhouse, regular ventilation helps against waterlogging.
