When and How to Plant Cucumber Seeds

Cucumbers thrive when soil temperatures reach at least 70°F (21°C). Delay sowing cucumber seeds outdoors until after your last frost for a successful growing season. For an earlier start, begin seeds indoors with our Deluxe Seed Starting Kit and follow these seed starting tips.

Direct sowing: Plant cucumber seeds about 1 inch deep and 18 inches apart in fertile, well-drained soil. Use raised beds or trellises to improve air circulation and ease harvest.

Indoor starting: Begin seeds 3–4 weeks before last frost and transplant when seedlings have 2–3 true leaves and nighttime temps exceed 60°F.

Caring for Your Cucumber Plants

Keep soil moist during fruit production, mulch to retain moisture, and avoid overhead watering to reduce powdery mildew risk. Monitor for pests like cucumber beetles, using neem oil or row covers if needed. Male flowers appear first, followed by female flowers requiring pollination for optimal fruit set.

Harvesting and Seed Saving

Harvest cucumbers when firm and vibrant in color. Frequent picking encourages continued fruiting. To save seeds, allow fruits to fully ripen, then rinse and dry seeds thoroughly before storage.
