How to grow eggplant at home:
Below is a simple eggplant sowing and growing guide to follow for first time growers.

  1. Sow seeds direct where they are to grow, in a sunny vegie patch, into well-drained soil that’s been enriched with soil improver ideally. Or seedlings can be raised in punnets of seed raising mix and transplanted when they’re around 6-8 cm high. Only transplant seedlings once the risk of frost has passed.
  2. Seedlings should pop up in around 10 -14 days.
  3. To encourage quality eggplant fruit development, as soon as the seedlings are established start feeding each week with a fertiliser, which is boosted with extra potassium which promotes flowering and fruit development.
  4. Water plants regularly to keep the soil moist. Mulch around the root zone to help retain soil moisture. Consistent soil moisture will help reduce the chance of blossom end rot.
  5. Eggplant fruit can be picked starting from 14 weeks after sowing.
  6. For best fruit quality, harvest when the skin is smooth and shiny. Cut fruit from the plant using secateurs, leaving 2 cm of stem on the fruit to improve storage.
  7. Regular harvesting will promote further flowering and fruiting.
  8. Monitor plants for pests such as whitefly and spider mites.

Planting eggplant in a pot:
Eggplants are quite happy in pots, but choose plants with smaller fruit, such as ‘White Star’ or Lebanese eggplants.

  1. Choose a pot at least 300mm wide and deep and position in full sun.
  2. Fill pot with a quality potting mix and ow seeds.
  3. Feed weekly with liquid plant food.
  4. A regular harvest promotes new growth.

When to harvest eggplant in Perth:
Eggplant is primarily self-pollinated, but is also partly cross-pollinated by bees. Fruit should be ready for harvesting 9 to 12 weeks from transplanting and about 30 days after flowering. Fruit is edible from one-third grown to full maturity, you can pick the fruit at any stage, depending on your requirements, but is usually picked at two-thirds full size.

Use secateurs to cut the fruit from the plant. The fruits should be firm and glossy. If they start looking dull, they’re past their best. They can still be eaten, but will be slightly more bitter and spongy.

Storing eggplant at home:
If you are curious how long does eggplant last? The answer is it depends on whether it has been stored correctly. To store correctly place uncut and unwashed eggplant in a plastic bag and store in the refrigerator crisper where it will keep for 3-5 days. If it is too large for the crisper, do not try to force it in; this will damage the skin and cause the eggplant to spoil and decay. Instead, place it on a shelf within the refrigerator.

Eggplant care and common problems:
Eggplants don’t seem to suffer from an enormous amount of pest and disease issues, but, being related to tomatoes and friends, they are susceptible to the same suite of pests and problems.  Grubs, spider mites, aphids and crusader bugs are pests to look out for.

Stake plants to keep them from falling over when they become heavy with fruit. Mulch to keep soil lightly moist.
