The Secrets to Growing Japanese Eggplant

About

• Japanese eggplants may grow up to about 4 foot tall and are tender plants. They are warm-season vegetables and need daytime temperatures between 80 and 90 degrees Fahrenheit, with nighttime temperatures no lower than 70 degrees F. The most essential requirement for successful eggplant cultivation is that they are planted in full sun.

Growing

• It's possible to grow your eggplants from seed but far easier to buy transplants from a local garden center. Grow your transplants in the indoor environment until any risk of frost has passed. Aim to plant them outside at least two to three weeks after the date for the last frost has passed; this gives the soil time to warm up.

Soil and Fertilizer

• Eggplants grow in most soils but prefer rich, organic types with good drainage. When preparing the soil, dig in a complete fertilizer at a rate of 1 pound to 100 square feet. Eggplants grow best in soil with pH levels of 6 to 7. The plants should be spaced 18 to 24 inches apart in rows that are 24 to 36 inches apart. Fertilize again midseason for best plant growth.

Harvesting

• The time from planting to harvest is approximately 100 to 150 days if grown from seed and 70 to 85 days if grown from transplants. The fruits should be harvested when they reach sufficient size and should not be allowed to remain on the plant, because the flesh becomes tough and seeds harden. Harvest your eggplants when they are large and a shiny purple color. When you press your thumb into the side of the fruit and it leaves an indentation, this is a sign that it is ripe.
