You can grow aubergine plants successfully by giving them plenty of warmth, sunlight, and consistent moisture throughout the growing season.
Aubergines, also known as eggplants, are heat-loving plants that thrive when you mimic the conditions of their native tropical habitat.
If you’ve been wondering how to grow aubergine plants from seed or transplant, the process is simpler than you might think once you understand what they need.
In this post, we’ll walk through everything you need to know about how to grow aubergine plants, from starting seeds indoors to harvesting ripe fruit.
Let’s dig in.
How to Grow Aubergine Plants: The Basics
Growing aubergine plants starts with understanding their needs.
1. Start Seeds Indoors Early
Aubergines need a long growing season, so start your seeds indoors about 8 to 10 weeks before your last frost date.
Sow seeds about a quarter inch deep in seed-starting mix and keep the soil warm, ideally between 75°F and 85°F.
A heat mat works wonders here because aubergine seeds germinate slowly in cool conditions.
Once seedlings emerge, give them plenty of light so they grow strong and stocky rather than leggy.
2. Choose the Right Location
When you’re ready to grow aubergine plants outdoors, pick a spot that gets at least six to eight hours of direct sunlight daily.
Aubergines love heat, so a south-facing bed or a sunny patio is ideal.
Make sure the soil drains well because soggy roots can quickly lead to disease.
If your summers are short or cool, growing aubergine plants in containers or a greenhouse gives you better control over temperature.
3. Prepare the Soil
Aubergines prefer rich, well-draining soil with a pH between 5.5 and 7.0.
Before planting, work in plenty of compost or aged manure to feed the plants and improve drainage.
If you’re growing aubergine plants in pots, use a quality potting mix and add a slow-release fertilizer.
Good soil preparation sets the foundation for healthy growth and a bigger harvest.
Caring for Aubergine Plants as They Grow
Once your plants are in the ground, consistent care keeps them productive.
1. Water Regularly but Don’t Overdo It
Aubergine plants need steady moisture, especially while flowering and fruiting.
Water deeply once or twice a week, aiming for about an inch of water each time.
Let the top inch of soil dry out between waterings to avoid root rot.
Mulching around the base helps retain moisture and keeps weeds down.
2. Fertilize at the Right Times
Feed your aubergine plants every two to three weeks with a balanced fertilizer once they start flowering.
Too much nitrogen early on gives you lots of leaves but few fruits, so switch to a formula higher in phosphorus and potassium when blooms appear.
If you’re growing aubergine plants in containers, they’ll need more frequent feeding since nutrients leach out faster.
3. Support and Prune
Tall aubergine varieties benefit from stakes or cages to keep them upright when loaded with fruit.
Pinch off the first few flowers to encourage stronger root development and bushier growth.
Remove suckers and any yellowing leaves to improve airflow and reduce pest problems.
You can also pinch the growing tips mid-season to redirect energy into fruit production.
4. Watch for Pests and Diseases
Flea beetles, aphids, and spider mites are common pests that attack aubergine plants.
Inspect leaves regularly and treat infestations early with insecticidal soap or neem oil.
Blossom end rot and verticillium wilt are the main diseases to watch for, and both are easier to prevent than cure.
Rotate your crops each year and avoid overhead watering to keep problems at bay.
Harvesting Aubergine Plants
Knowing when and how to harvest is the reward for all your effort.
1. When to Pick
Most aubergine varieties are ready 65 to 80 days after transplanting.
Harvest when the skin is glossy and firm and the fruit feels heavy for its size.
If the skin dulls or the fruit starts to soften, it’s past its prime, so pick earlier rather than later.
Use pruning shears to cut the stem rather than pulling, which can damage the plant.
2. Keep Picking for More Fruit
The more you harvest, the more fruit your aubergine plants will produce.
Check plants every few days during peak season and remove ripe fruit promptly.
Leaving overripe aubergines on the plant signals it to stop producing, so stay on top of picking.
So, How to Grow Aubergine Plants?
You can grow aubergine plants by starting seeds indoors early, planting them in a sunny, well-drained spot, and keeping them watered and fed all season.
With warmth, sunlight, and a little patience, your aubergine plants will reward you with a steady supply of glossy, delicious fruit.
Whether you’re growing aubergine plants in beds, pots, or a greenhouse, the key is giving them the heat and care they crave.
Happy growing.
