Start seeds indoors 8-10 weeks before the last frost date in your area. Transplant seedlings outdoors once soil temperatures are above 65 F, and nighttime temperatures remain above 55 F. In cooler regions, row covers or black plastic mulch can help warm the soil and extend the growing season. If you are not sure how to find your local frost dates, check out our blog post 'Our Experts Answer Questions, Share Resources' to help you determine the best planting schedule.

Sow seeds 1/4 inch deep in seed-starting mix, maintaining a soil temperature of 75-85 F for germination. Use a heat mat to keep the soil warm if necessary. Once seedlings have 2-3 sets of true leaves, transplant them into the garden, spacing plants 18 inches apart. Choose a sunny location enriched with compost or organic matter and apply mulch to conserve moisture and suppress weeds.

Water the plants deeply and regularly to keep the soil evenly moist but not waterlogged. Mulch helps prevent temperature fluctuations and retains moisture. Harvest fruits when they are firm, glossy, and about 3-4 inches in diameter. Continually harvest to keep plants productive.

• 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.
