When to Plant Eggplant. Start eggplant seeds indoors about six weeks before your last spring frost, or about two weeks after tomatoes and peppers. Eggplant seeds germinate best at temperatures above 75 degrees Fahrenheit. Bottom heat is useful in getting the plants up and growing.rowing eggplant is easy where summers are long and warm. Where summers are short, varieties that mature quickly and produce medium to small fruits can easily be grown in containers. If you grow peppers, you can grow eggplant.
