Frequently Asked Questions

What’s a common disease or pest problem for Cucumis sativus (cucumber) and how can I control it in my home garden?

Powdery mildew commonly affects Cucumis sativus, especially once vines start heavy growth. Water at the base (not the leaves), improve airflow by keeping rows from crowding, and remove badly infected leaves early to slow spread. If needed, use a labeled horticultural sulfur or potassium bicarbonate product and spray according to the label at first signs and again as directed.

How often should I water Cucumis sativus during the main growing phase?

During active vine growth and fruiting, keep the soil consistently moist but not soggy—aim for about 1 inch (2.5 cm) of water per week, split into 2–3 deep waterings if it’s hot. Cucumis sativus is sensitive to uneven moisture; letting it swing dry to wet can cause misshapen fruit and bitterness. Mulch around the plants to reduce moisture fluctuations, and water early in the day so foliage dries quickly.

How do I tell when Marketmore 80 cucumbers are ready to harvest?

Harvest when fruits are small and firm—about 55 days after sowing for maturity—with typical picking sizes around 8–9 inches (20–23 cm). Check daily during peak production: Cucumis sativus quickly becomes seedy and less crisp if you leave fruit too long. Cut the cucumbers from the vine with a knife or pruners to avoid tearing vines, which helps keep the plant producing.
