Planting, caring for and harvesting eggplants – how to grow them in your own garden
The eggplant ( Solanum melongena ), also known as the "eggplant," is a true star of Mediterranean cuisine—whether in moussaka, ratatouille, or grilled. But did you know that you can also successfully grow eggplants in your own garden or greenhouse? With a little patience, warmth, and care, you'll soon be harvesting aromatic, purple fruits. In this article, you'll learn everything you need to know about growing eggplants, the right time to sow, suitable varieties, care tips, harvest time, and their interesting origins.

Planting time: When to sow eggplants?
Eggplants should be started early in late February because they grow very slowly. Sow indoors or in a greenhouse, ideally at temperatures between 21 and 30°C. Depending on the weather, the young plants can be planted outdoors in late spring or early summer—when the risk of frost has passed.
Growing eggplants: step by step
- Soak in warm water one day before sowing
- Sow in seed trays or small pots with seed compost (0.5 cm deep)
- Warm environment (21–30 °C), high humidity (mini greenhouse ideal)
- As soon as the plants are about 5 cm high, transplant into individual pots
- When the plant is 8-10 cm tall, acclimatise to the outdoors during the day
- Plant in the bed at a distance of 60–75 cm, support with stakes
Many varieties produce their first flowers early – a good indication that the plant is strong enough to be moved into the garden.
Location & soil: How to optimally grow eggplant
Eggplants prefer sunny, warm, and wind-protected locations. The soil should be deep, well-drained, and rich in humus. Fertilizing with compost before planting improves the nutrient supply.
Care: What you should pay attention to
- Water regularly and thoroughly (never let it dry out!)
- Keep weed-free so that young plants can grow undisturbed
- Fertilize with tomato or universal fertilizer for strong fruits
- Limit the amount of fruit: 6–10 fruits per plant are sufficient for all to ripen well
- Remove first fruits to stimulate plant growth
Harvest: When are eggplants ripe?
You can recognize ripe eggplants by their shiny skin, slight yield when pressed, and white to slightly colored flesh.
If the skin is dull and the flesh is soft, the fruit is overripe. Uncooked fruit will keep for about a week in the refrigerator.
Good neighbors: What goes well with eggplant in the garden?
Suitable planting partners are beans, radishes, lettuce.
Tomatoes, peppers and potatoes (all nightshade plants) are less suitable.
Botanical knowledge: The eggplant at a glance

Cultural history: Where does the eggplant come from?
The eggplant originally comes from Asia, especially China and India. The first fruits were whitish and egg-shaped – hence the name “egg fruit”.
It came to Europe via the Arab world in the 13th century, but was not cultivated in Italy until the 15th century. Today, it is an integral part of vegetable cultivation in Southern Europe, North Africa, and the Netherlands.
Conclusion: Growing eggplants successfully in the garden
With proper preparation and a warm location, eggplant can be easily cultivated even in our latitudes. It will reward you with aromatic fruits and a Mediterranean flair – straight from your own garden.
