Description

(Solanum melongena). This elegant apple green eggplant is a culinary treasure of Japan. This traditional variety has been grown in Saitama Prefecture since the early Meiji period. A dense and creamy texture makes this a highly gourmet choice. Uniquely colored and globe-shaped with a flat bottom.

Growing Tips: Saitama Ao Daimaru is a rare heirloom eggplant that thrives in full sun and nutrient-rich, well-draining soil with a pH of 6.0-7.0. This heat-loving variety requires consistent watering to keep the soil evenly moist but not waterlogged. Mulching around the plant helps retain moisture and regulate soil temperature. Use a balanced fertilizer or one slightly higher in phosphorus and potassium to encourage flowering and fruit production.

Growing Guide

When to Grow

Start seeds indoors 8-10 weeks before the last frost date. Transplant seedlings outdoors when soil temperatures reach 65 F, and nighttime temperatures stay above 55 F. For shorter growing seasons or cooler regions, use row covers or black plastic mulch to warm the soil and protect plants. In warm, frost-free areas, seeds can be sown directly into the garden once the danger of frost has passed. 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.

How to Sow and Plant

Sow seeds 1/4 inch deep in seed-starting mix, maintaining a soil temperature of 75-85 F for germination. Transplant seedlings outdoors once they develop 2-3 sets of true leaves, spacing plants 18 inches apart in rows about 24 inches apart. Setting out larger transplants helps to fight pest pressure. Apply mulch to retain moisture and reduce weed growth.

How to Grow

Water deeply and regularly, keeping the soil moist but not soggy. Mulching helps conserve moisture and stabilize soil temperature. Fruits mature 70-80 days after transplanting and should be harvested when they are firm, shiny, and about 4-5 inches in diameter. Harvest regularly to keep the plants productive throughout the season.

How to Save Seeds

  • 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.
