Eggplant Seeds,
Shiromaru

Start seeds indoors 8-10 weeks before your area's last frost date. Eggplants need warm weather, so transplant them outdoors only after the soil is at least 65 F and nighttime temperatures stay above 55 F. In cooler climates, use row covers or plant in a greenhouse to provide the warmth needed for growth.

Sow seeds indoors in seed trays or small pots filled with seed-starting mix. Plant seeds about 1/4 inch deep and keep the soil moist. Maintain a consistent temperature of 75–85 F for germination, which usually takes 7–14 days. When transplanting, space plants 18 inches apart in rows spaced 2–3 feet apart. Choose a sunny, sheltered location.

Water the plants deeply once a week, or more often in hot weather, to keep the soil evenly moist. Add a layer of organic mulch around the plants to help retain moisture and regulate soil temperature. Feed plants regularly with a balanced fertilizer (5-10-10) or side-dress with compost or aged manure. Watch for common pests like flea beetles, aphids, and spider mites. Neem oil or insecticidal soap can help control infestations.

• Eggplants are not insect-pollinated, so it is not necessary to isolate the plants very much to ensure pure seed. For home gardeners, an isolation distance of at least 40 feet is sufficient for seed saving.
• Allow fruit to become overripe; the fruit will become slightly wrinkled and soft.
• Scoop seeds out, rinse, and spread out to dry thoroughly.
• Properly stored eggplant seeds will remain viable for up to 4 years.
