Eggplant Seeds,
Rosa Bianca

Start the seeds indoors 8-10 weeks before the last frost date. Transplant seedlings outdoors after all risk of frost has passed, and the soil has warmed to at least 65 F. Rosa Bianca grows best in USDA zones 6–10, but cooler climates can extend the season by using row covers, black plastic mulch, or a greenhouse to maintain warmth.

Sow seeds 1/4 inch deep in seed-starting mix, maintaining a soil temperature of 75–85 F for optimal germination. Once seedlings have developed several true leaves, harden them off 7–10 days before transplanting. Space plants 18 inches apart. Apply mulch around the plants to retain moisture, suppress weeds, and regulate soil temperature.

Water deeply 1–2 times per week, keeping the soil evenly moist but not waterlogged. Fertilize with a balanced or high-potassium fertilizer when plants begin flowering and setting fruit. Use row covers to protect against pests like flea beetles, and maintain airflow to prevent fungal diseases. Harvest when fruits are firm, glossy, and about 5–6 inches in diameter. Use a sharp knife or pruners to cut the fruit, leaving a short stem attached. 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.
