Description

(Solanum melongena). A dark obsidian eggplant from Niigata Prefecture, Japan—an area famous for rice production. This district is also known for its eggplant varieties, which are raised in the time between the planting and harvest of the region’s main crop. Each of the eggplant varieties has its own uses. This variety, known as “Nagaoka purse eggplant,” dates back to the middle of the Meiji era (1868-1912). This variety is known to be among the sweetest and is traditionally steamed with a bit of ginger and soy sauce.

Growing Tips, Tricks and FAQs

Growing Tips

This Japanese heirloom eggplant grows best in full sun and nutrient-rich, well-draining soil with a pH of 6.0-7.0. This heat-loving plant requires even moisture but dislikes soggy soil, so be careful not to overwater. Mulching helps retain moisture and regulate soil temperature. Use a balanced or phosphorus-rich fertilizer to encourage flowering and fruiting while avoiding excessive nitrogen, which promotes leafy growth.

When to Grow

Start seeds indoors 8-10 weeks before the last frost date. Transplant seedlings outdoors when the soil temperature stays consistently above 65 F. In cooler climates, row covers or black plastic mulch can help extend the growing season. In warm regions, seeds can be sown directly into the garden once frost danger has passed.

How to Sow and Plant

Sow seeds 1/4 inch deep in seed-starting mix, keeping soil temperatures between 75-85 F during germination. It typically takes around 10-15 days. Transplant seedlings outdoors when they develop 2-3 sets of true leaves, spacing them 18 inches apart. Choose a sunny location, enrich the soil with compost, and apply mulch to conserve moisture and suppress weeds.

How to Grow

Water the plants regularly to keep soil evenly moist but not waterlogged. Mulching helps retain moisture and keeps the soil warm. Fruit is mature when just slightly soft; immature fruit will feel rock hard. Continually harvest to keep plants productive.

How to Save

  • 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.
