How do Eggplants Grow

Eggplants, or Solanum melongena, are part of the Nightshade family which includes other popular garden vegetables like tomatoes and pepper. Across the globe, the eggplant is often referred to as an aubergine. 

Native to India and China, there is a range of eggplant types, including small-fruited varieties. The most well-known is, of course, the large, purple, pear-shaped variety which is often available in stores.

These tall, angular plants grow along an upright stem, and many smaller varieties are heavy bearers. Eggplants contain a striking water-soluble flavonoid pigment which causes the deep purple colour of the fruits and flowers. 

The Best Types of Eggplants to Grow

There is a range of eggplant cultivars, most grown for their fruit and some for their ornamental value. 

The most common varieties grown in America include:

  • Black Magic
  • Black Beauty
  • Black Bell

Other popular varieties include:

  • Silician. A smaller, striped cultivar. 
  • Albino. A curious cultivar that grows white fruit. 
  • Japanese. A smaller, long-growing cultivar is often referred to as “Ichiban Eggplant”.

How to Grow Eggplants

How to Grow Eggplants

As eggplants thrive in warmer climates, it’s important to hold off on planting until the last frosts have gone and temperatures start to rise above 50°F. 

Eggplants grow best in overly sunny positions, with rich, well-draining soil. Especially when growing in the ground, it’s recommended to enrich your soil with a good mix of compost and other organic matter.

Mulching around the base of your eggplant plant will help to keep the soil warm and moist and keep it from drying out in the summer heat. This could be done with hay, shredded leaves, pine needles or a similar organic matter. 

Whether you’re planning on planting in a raised bed, pot or in your garden, it is a good idea to support your stem with a stake. 

Even in smaller-fruiting varieties, the eggplant fruits can grow to a significant size, meaning they begin to weigh down the stems.

Planting Eggplants

Planting eggplants in a sunny spot

Whether growing from seed or planting eggplant bought at a garden centre, consider spacing your eggplants around 24-36 inches apart. 

This will allow plenty of space for each plant to grow and receive sufficient sunlight to fruit. 

To plant simply: 

  • Pick a sunny spot to locate your eggplant.
  • Enrich your soil by mixing in organic compounds and a slow-release granular fertilizer. 
  • Dig a hole twice the size of the root ball. 
  • Gently place into the hole and backfill. Gently patting down the top layer of soil to remove air pockets. 
  • Start with a smaller stake at the base of the plant, and increase stake height as your eggplant begins to grow.

How to Grow Eggplant from Seed

Growing eggplants from seed is a viable option. However, it is important to wait for warmer weather before planting your seeds.

Seeds need an ambient soil temperature between 75°-85°F. For colder regions, a heating mat can be placed beneath the seeding tray. 

Here is how to plant eggplant seeds:

  • Prepare a seeding tray with a moist, seeding mixture. 
  • Embed your eggplant seeds about a ¼ inch deep into the soil. 
  • Keep your seedlings in warm, well-light areas and water often.

In the right conditions, seeds take around 2 to 3 weeks to germinate.

Growing Eggplants from Cutting

If you don’t have the patience to grow from seed, you can grow your eggplant from a cutting to save time. 

Cuttings should be taken from existing plants after the growing season. 

You will need to:

  • Remove a stem cutting with 1 or 2 larger, healthy leaves. 
  • Place the cuttings into a mason jar, filled 2/3 with water. 
  • Check on the water daily and replenish if the water discolors or evaporates. 
  • Roots should appear after 2 to 3 weeks. Then, transplant into a pot with a rich soil mixture.

Keep young plants in a warm and sheltered area before transplanting outdoors or into the garden.

How to Care for Eggplants

How to Care for Eggplants

Eggplant care is relatively easy once the plants are established. Do your best to keep the soil moist during the growing season. Eggplants need a steady supply of moisture, or you may risk your eggplant bearing bitter fruit. 

Most gardeners recommend using a soaker hose. You can also support your plant with a balanced fertilizer throughout the growing season. 

Should you experience a sudden cold spell, it is recommended to bring your eggplant inside overnight or to cover them with row covers. 

Pruning will not be required with eggplants, if only just to remove dead and damaged leaves or spent flowers. It is important to note that eggplants require pollinators, such as bees, to help them pollinate and bear fruit. 

Many gardeners will opt to grow their eggplants along with other flowering garden plants to help attract pollinators. If growing in your vegetable garden, you could always choose to plant edible flowers along with your eggplants.

Harvesting Eggplants

Harvesting eggplants using a sharp pair of gardening shears

The trickiest part of growing eggplants at home will be knowing when to harvest. Even for the most experienced gardeners picking the perfect moment to harvest is an art. 

Harvesting your eggplant too late or too early can result in a bitter flavour. You’ll know your eggplant is ready for harvest as soon as the fruit stops growing and the skin starts to become glossy. 

You will want to remove your eggplant using a sharp pair of gardening shears. It is advised to cut the stem slightly above the stub.

Avoid trying to tug the eggplant loose, as they don’t tend to drop very easily, and you’ll risk damaging the fruit. You can store your eggplant in the fridge for up to one week. 

When preparing your eggplant, you’ll want to work quite quickly as eggplants tend to discolor when sliced. 

Eggplant Problems

Sometimes eggplants can be susceptible to disease or pest invasions; as such, it’s a good idea to regularly check on your eggplant. 

Aphids, whiteflies and the black flea beetle all tend to enjoy feasting on the eggplant’s foliage. These can be easily treated with insecticidal soap. 

Blossom end rot, wilt and various types of blight can also affect your eggplant.
