How To Grow Aubergine Plants

You can grow aubergine plants successfully by giving them plenty of warmth, sunlight, and a long growing season.
 
Aubergines, also known as eggplants, are heat-loving plants that thrive when the conditions are just right.
 
If you’ve ever wondered how to grow aubergine plants from seed or starter plants, the good news is that it’s totally doable even for beginners.
 
The key is to treat them like the tropical plants they are and pamper them a little along the way.
 
In this post, we’ll walk through how to grow aubergine plants step by step, from sowing seeds to harvesting glossy, ripe fruit.
 
Let’s dig in.
 

How to Grow Aubergine Plants From Seed

Growing aubergine plants starts long before you ever see a flower.
 
These plants need a head start because they take their sweet time maturing.
 
Here’s how to get them going:
 

1. Start Seeds Indoors Early

Aubergine seeds need warmth and a long season, so start them indoors about 8 to 10 weeks before your last frost date.
 
Sow the seeds about a quarter inch deep in seed-starting mix.
 
Keep the soil consistently moist but not soggy, and place the trays somewhere warm, ideally around 75 to 85°F.
 
A heat mat works wonders here because aubergine seeds germinate slowly in cool conditions.
 

2. Give Seedlings Plenty of Light

Once your aubergine seedlings pop up, they need bright light for at least 12 to 14 hours a day.
 
A sunny south-facing window works, but grow lights are even better.
 
Weak light leads to leggy, spindly plants that struggle later on.
 
Healthy aubergine seedlings should look sturdy and compact, not stretched out.
 

3. Harden Them Off Gradually

Before transplanting aubergine plants outdoors, harden them off over a week or two.
 
Set them outside for a few hours each day, increasing the time slowly.
 
This helps them adjust to wind, sun, and temperature swings without going into shock.
 

Best Conditions for Growing Aubergine Plants

Aubergine plants are fussy about their environment, but once you nail the basics, they reward you generously.
 
Here’s what they need to thrive:
 

1. Full Sun and Warmth

Give your aubergine plants at least 6 to 8 hours of direct sunlight every day.
 
They absolutely love heat and grow best when daytime temperatures sit between 70 and 85°F.
 
If it drops below 50°F at night, growth slows down and fruit may not set properly.
 

2. Rich, Well-Draining Soil

Aubergine plants feed heavily, so plant them in fertile, well-draining soil rich in organic matter.
 
Mix in plenty of compost before planting and keep the soil pH between 5.8 and 7.2.
 
Raised beds or large containers work great if your garden soil is heavy clay.
 

3. Consistent Watering

Water aubergine plants deeply once or twice a week, letting the top inch of soil dry out between waterings.
 
Uneven watering can cause blossom end rot and cracked fruit.
 
Mulching around the base helps retain moisture and keeps the roots cool and happy.
 

4. Feed Them Regularly

Aubergine plants are hungry and benefit from a balanced fertilizer every two to three weeks.
 
Once flowers appear, switch to a feed higher in phosphorus and potassium to support fruit development.
 
Don’t overdo the nitrogen, though, or you’ll get lots of leaves and barely any aubergines.
 

Caring for Aubergine Plants as They Grow

A little ongoing care goes a long way when growing aubergine plants.
 
Keep an eye on these things throughout the season:
 

1. Stake Tall Varieties

Many aubergine plants grow tall and top-heavy once fruit starts forming.
 
Use stakes or cages to keep them upright and prevent branches from snapping.
 

2. Watch for Pests

Flea beetles, aphids, and spider mites love aubergine plants.
 
Check the undersides of leaves regularly and treat infestations early with insecticidal soap or neem oil.
 

3. Pinch and Prune When Needed

Remove suckers and any yellowing lower leaves to improve airflow.
 
Pinching off the growing tip late in the season redirects energy into ripening existing fruit.
 

4. Harvest at the Right Time

Aubergine fruit is ready when the skin is glossy and firm and the fruit feels heavy for its size.
 
Dull, wrinkled skin means you waited too long.
 
Cut the fruit off with pruners rather than pulling, since aubergine stems are tough.
 

So, How Do You Grow Aubergine Plants?

You grow aubergine plants by starting seeds indoors early, giving them full sun and warmth, and keeping them well-fed and watered.
 
Aubergines are heat-loving, hungry plants that need a long season and a bit of patience.
 
Once you get the conditions right, growing aubergine plants is genuinely rewarding and you’ll be harvesting fresh fruit before you know it.
 
Happy growing.
