4. Warmth and Sunlight
When it comes to growing eggplants you want to make sure that you are planting your eggplants in an area that will receive at least six to eight hours of sunlight each day. The plants need this much full sunlight each day in order to grow well. If the eggplants are in the shade too much the plants may become leggy. The shade will also minimize the amount of fruit that you get from them.
Eggplants are a warm-weather plant, which means that they do best in soil that is warm. You can increase their growth by laying some black plastic over the garden soil several weeks before you are planning to transplant your seedlings. This will help to keep the ground warm and will lead to much better fruit production.
You can also mulch around the eggplants with some dark compost, which will help to heat the ground more and keep the soil around the plants at the temperature that they desire.
