Growing eggplant under its ideal conditions will increase your chances of a successful fruit harvest.
Eggplant grows best in hot climates (its optimum growing temperatures range from 70°F to 90°F). After planting, you should be able to have an abundant summer harvest after 70 to 90 days, depending on the variety you're growing.
Eggplant likes its soil hot and neutral. Shoot for a pH between 5.5-7.5.
Full sun is non-negotiable when growing this purple beauty.
Eggplant loves phosphorus and potassium to help it form fruit. Apply a balanced fertilizer such as a 10-10-10 or make sure your nitrogen (the first number) is lower to avoid too much leaf production. I like to add fresh compost around the base of my eggplant plants every couple of weeks to support them.
Eggplant requires up to 1” a week. Water deeply and less often for strong root growth. Your first instinct might be to add mulch around your eggplant to keep the water from evaporating, but since eggplants welcome hot soil, it's best to wait until the plant is mature before offering any cover. I don’t tend to be a big "mulcher". As long as you’re supplying your quarterly compost treatment, your plants should be fine.
Other nightshade veggies, such as hot or sweet peppers, are great to plant with eggplants because they mostly require the same nutrients. Marigolds on the perimeter will help attract beneficial insects and keep away pests. Chard, spinach, or arugula planted beneath the eggplant will welcome the dappled shade and help retain moisture in the soil. Herbs such as oregano, basil, or dill will also do a great job of deterring pests.
