What are Green Eggplants?

Green eggplants, though less common than their purple counterparts, are a unique variety of the Solanum melongena species.

They range in shade from light jade to a rich forest green and can vary in size from small and round to elongated or bell-shaped.

The flavor of green eggplants is similar to the classic purple variety, though some find it slightly milder and less bitter.

Green Eggplant Varieties

Green eggplants, while less common than their purple counterparts, come in several delicious and unique varieties. These green varieties are often praised for their slightly different flavors and textures, which some people find to be less bitter and more tender than typical purple eggplants.

Here are some of the most common varieties of green eggplants:

Thai Green

  • Description: These are small, round to oval eggplants that are commonly used in Thai cuisine. They have a bright green skin and a somewhat sweet flavor.
  • Usage: Ideal for stir-fries, curries, and other Thai dishes.

When choosing a green eggplant variety to grow, it's essential to consider your climate and intended culinary use.

Additionally, just like their purple counterparts, green eggplants are nutrient-rich and can be a healthy addition to various dishes.

Growing Green Eggplants: A Gardener's Guide

Green eggplants are relatively easy to grow; just plant them at a good location with good soil and plenty of sun and provide them with enough water and nutrients.

Choosing a Location

Like their purple siblings, green eggplants thrive in full sunlight and warm conditions. Select a spot in your garden that receives at least 6-8 hours of direct sunlight daily. The more sun they get, the more productive they'll be.

A location that receives morning sun is preferable as it can dry the dew on the leaves, reducing the risk of fungal diseases.

Eggplants, while sturdy, can be damaged by strong winds, especially when laden with fruit. Choose a location that's shielded from strong gusts, or be prepared to provide some sort of windbreak, like a fence or tall plants.

If you've grown related crops (like tomatoes, peppers, or potatoes) in a spot recently, avoid planting eggplants there for at least two to three years. This rotation minimizes the risk of soil-borne diseases.

While this doesn't directly affect the eggplants' growth, selecting a spot that's easy for you to access will make monitoring, watering, pruning, and harvesting more convenient.

Soil Prep And Fertilization

Eggplants dislike "wet feet," which can lead to root rot and other diseases - they prefer well-draining soil with a pH level between 6.3 and 6.8. If uncertain about your soil's pH, a soil test can be conducted using a test kit.

Enrich the soil with organic compost, aged manure, worm castings, or some other organic matter to ensure healthy growth. This not only improves soil texture but also provides essential nutrients.

When fertilizing the eggplants, be sure that the plants receive enough of all essential nutrients; just keep the nitrogen in check, especially when the plants start to flower and young eggplants start to form.


Start seeds indoors 8-10 weeks before the last frost date. Once the danger of frost has passed and seedlings have grown at least 6 inches tall, transplant them outdoors, spacing them 18-24 inches apart.

Eggplants need ample space for their roots to spread and grow. Ensure the location you choose allows you to space the plants at least 18-24 inches apart, with rows about 30-36 inches apart.

Green eggplants can also be grown in pots and containers; just be sure to use larger ones and keep the number of plants in pots to a minimum, preferably only one plant per pot/container.


Watering is crucial for eggplants (Solanum melongena) to ensure they produce plump and healthy fruits. Here’s a guide to help you understand how, when, and how much to water your eggplants:

Watering Technique

  • Soaker Hose or Drip Irrigation: These are preferred because they deliver water directly to the roots without wetting the leaves. Wet leaves can lead to fungal diseases.
  • Watering Can or Hose: If using these, try to water the base of the plant, avoiding the foliage.
  • Water Depth: Aim to water deeply, so the moisture reaches the roots. A shallow watering promotes surface roots which are more susceptible to drought and heat.
  • Mulching: Apply a layer of organic mulch (like straw or wood chips) around the base of the eggplants. This conserves moisture, suppresses weeds, and keeps the soil temperature consistent.

When To Water Eggplants

  • Seedlings/Transplants: Young plants need consistent moisture. Water them when the top inch of soil starts to feel dry. Do not let them wilt, as this can stunt their growth.
  • Flowering Stage: Consistent moisture is vital during this phase to ensure flowers don't drop and fruits set well.
  • Fruit Development: Eggplants need water to develop healthy fruits. Irregular watering at this stage can cause issues like blossom end rot or misshapen fruits.
  • Drought Conditions: In excessively hot or dry conditions, increase the frequency of watering.
  • Soil Check: A simple method is to stick your finger about an inch into the soil. If it feels dry at this depth, it's time to water.

How Much Water Is Actually Needed

  • General Guideline: A good rule of thumb is to provide at least 1 to 1.5 inches of water per week. This can be adjusted based on rainfall and soil conditions.
  • Container-Grown Eggplants: Plants in pots dry out faster than those in the ground. Check them daily, especially in hot weather. Ensure pots have drainage holes so excess water can escape.
  • Soil Type: Sandy soils drain faster and may require more frequent watering compared to clay soils, which retain moisture longer.
  • Weather Conditions: On hotter days, eggplants may require more water. Conversely, reduce watering during rainy spells to prevent over-saturation.

Always observe your plants, eggplants included, and adjust watering practices according to their needs.

Overwatering can lead to root rot while underwatering can stress the plant and reduce yield. Keeping a balance is the key to a thriving eggplant garden!

Eggplants, while not as tall or vining as some other plants, can still benefit from support. As they develop heavy fruits, branches can become weighed down and may even break.

Providing support can help prevent these issues and keep your plants upright, healthy, and producing optimally.


  • Materials: Use sturdy stakes made of wood, bamboo, or metal. These should be at least 4-5 feet tall.
  • Installation: Insert the stake about 12-18 inches into the ground, a few inches away from the plant's base, ideally when the plant is still young. Be cautious not to damage the roots.
  • Tying: As the eggplant grows, tie the main stem and heavy branches to the stake. Use soft ties, like cloth strips, garden twine, or specialty plant ties. Ensure ties are snug but not too tight, allowing some room for growth.


  • Materials: Tomato cages or specially designed eggplant cages can be used. They should be sturdy and at least 3-4 feet tall.
  • Installation: Place the cage over a young plant, pushing it into the ground to stabilize. The plant will grow up through the cage, and its branches will be supported by the cage's rings.

Tips for Supporting Eggplants

  • Install Early: It's easier and less risky to install supports when eggplants are young, as you can avoid damaging established roots or stems.
  • Regular Checks: As the plant grows, regularly check to ensure that ties aren't too tight and that all branches bearing fruits are supported. Adjust as necessary.
  • Avoid Damage: When inserting stakes or other supports, be cautious to avoid damaging roots. When tying stems, be gentle to prevent breaking or bruising them.
  • Spacing: If you're using cages or other wide supports, ensure that you've adequately spaced your eggplants to account for the added width of the supports.

Supporting your eggplants can prevent many potential issues, ensuring that the plant’s energy goes into producing a bountiful harvest.

Plus, a well-supported eggplant patch is easier to navigate, looks tidy, and simplifies tasks like pruning and harvesting.
