Eggplant Care

Eggplant care tips for growing.

Eggplants are warm-season vegetables normally grown in backyard gardens or containers. By following the tips below, you can successfully grow healthy, delicious eggplants.


The best soil to grow eggplants is well-draining, fertile soil with a pH between 6.0 and 6.8. It’s a good idea to add compost to improve soil fertility.


Eggplants are generally considered to be moderate to heavy water users. But they can also be sensitive to fluctuations in soil moisture. So, check the soil moisture level often and water as needed.

It is best to water eggplants consistently and deeply. Provide about 1 inch of water per week to thoroughly wet the root zone. But water around the base of the plant to avoid getting the leaves wet. As this will decrease the chances of fungal diseases developing.

Pay close attention during fruiting, as too little water can cause stunted or misshapen fruit. Mulching around your eggplants with help suppress weeds and retain moisture.


Eggplants should be planted in a location that receives direct sunlight. Eggplants grow best when they receive 6-8 hours of sunlight.

Temperature Range

Eggplants thrive in warm temperatures, between 70°F and 85°F (21°C -29°C ). If temperatures rise above 95°F, they stop setting fruit, and blossom drop can occur. When temperatures fall below 60°F fruit set is also reduced.

Fertilizing Eggplant

Eggplants are heavy feeders and benefit from regular fertilizing. Before planting mix in a balanced fertilizer with an NPK of 10-10-10 or 13-13-13 into the soil[1]. Once plants are established, fertilize them every 2-4 weeks during the growing season.

When plants start to fruit, you want to avoid using too much nitrogen. As this will encourage the growth of foliage instead of fruit production.

Diseases & Pests

Several diseases and pests are common when growing eggplants. Some of the diseases are fusarium wilt, bacterial wilt, verticillium wilt, and powdery mildew. Most are fungal diseases, watering at the base of the plants and adding mulch can help avoid them. As well as crop rotation if diseases become an issue.

Pests include aphids, cutworms, flea beetles, and tomato fruitworms. There are many organic pesticide options to eliminate these pests.

Days to maturity

Depending on the variety, eggplants can take 60 to 75 days to mature from seedlings. From seed, add another 21 to 28 days. However, environmental factors like soil fertility and temperature can also affect the time to maturity.

How to Grow Eggplant from Seed

Start your seeds indoors about 8-10 weeks before the last frost in your area. You can follow these steps:

  1. Fill a pot, container, or seed tray with a moist seed starting mix.
  1. Sow the seeds about 1/4 inch deep and cover them lightly with soil and mist them with water.
  1. Place the seed tray or pot in a warm, sunny spot with temperatures around 70°F-75°F to germinate. Keeping the soil moist but not waterlogged, until seedlings emerge.
  1. After all danger of frost has passed and the soil has warmed up, transplant the seedlings into the garden. You can also harden off the seedlings first. By exposing them to the outdoor elements a few hours a day for a week or two.

Marigolds are a popular companion plant in the garden for deterring pests. They help deter nematodes from attacking the roots of eggplants.

Borage can help deter tomato hornworms that also feed on eggplant foliage. Its blue flowers attract pollinators to the garden. Helping to pollinate and increasing yields.

Radishes make good companion plants for eggplants. Because they have different nutrient needs and help deter pests. Such as flea beetles and cucumber beetles.
