Frequently Asked Questions

Why are my Cucumis sativus (cucumber) leaves turning yellow with fuzzy gray patches, and what should I do?
Fuzzy gray growth and spotting that spreads on leaves/stems is often gray mold (Botrytis), which is common when foliage stays wet and nights are cool. Remove affected leaves immediately, improve airflow with wider spacing and by training vines upward if possible, and water at the soil line in the morning to keep leaves dry. If it keeps worsening, switch to a labeled fungicide for cucurbits and follow the product’s interval closely.
How can I tell when my Cucumis sativus is ready to harvest (and when to pick to keep producing)?
Harvest cucumbers when they reach the variety’s typical size for eating and the skin is firm, glossy, and still easy to puncture with a fingernail. Pick regularly—about every 1–3 days once fruits start—to prevent overgrown, seedy cucumbers and to encourage continued flowering. If fruits start looking dull or the ends turn hard, they’re usually past their best harvest window.
