You grow aubergines by starting them indoors early, keeping them warm, and giving them plenty of sunshine and water.
Aubergines, also known as eggplants, are heat-loving plants that thrive when you give them the right conditions from the very beginning.
If you’ve ever wondered how do you grow aubergines successfully, the answer lies in warmth, patience, and a little bit of know-how.
These beautiful purple vegetables aren’t difficult to grow once you understand what they need.
In this post, we’ll walk through exactly how do you grow aubergines from seed to harvest, covering everything from starting seeds to dealing with common problems.
Let’s dig in.
How Do You Grow Aubergines From Seed?
Growing aubergines from seed is the most rewarding way to start, and it all begins indoors.
Here’s how do you grow aubergines from seed step by step:
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.
This gives them plenty of time to grow strong before they go outside.
Fill small pots or seed trays with seed-starting mix and sow the seeds about a quarter inch deep.
Keep the soil warm, ideally between 75°F and 85°F, because cold soil will slow germination to a crawl.
A heat mat works wonders here if you have one.
2. Give Them Plenty of Light
Once your aubergine seeds sprout, they need lots of light to grow strong and stocky.
Place them under grow lights or in a sunny south-facing window for at least 12 to 14 hours a day.
If you’re growing aubergines indoors, keep the lights close to the plants so they don’t stretch and become leggy.
Weak, spindly seedlings rarely turn into productive plants, so don’t skimp on light.
3. Harden Them Off Before Planting Out
Before you move your aubergines outside, you need to harden them off over about a week.
Start by putting them outside for just an hour or two in a sheltered spot, then gradually increase their time outdoors each day.
This helps them adjust to wind, sun, and temperature changes without going into shock.
By the end of the week, they’ll be ready to plant in their permanent home.
Where and How Do You Grow Aubergines Outside?
Knowing how do you grow aubergines outside means giving them the warmest, sunniest spot in your garden.
Aubergines love heat and hate the cold, so wait until nighttime temperatures stay consistently above 50°F before planting them out.
1. Choose the Right Location
Pick a spot that gets at least 6 to 8 hours of direct sunlight every day.
The more sun, the better your aubergines will grow and fruit.
If you live in a cooler climate, planting them against a south-facing wall or in a greenhouse can make a huge difference.
2. Prepare the Soil Well
Aubergines grow best in rich, well-draining soil with plenty of organic matter.
Mix in compost or well-rotted manure before planting to give them a nutrient boost.
The soil should also be slightly acidic to neutral, around pH 5.8 to 7.0.
Good drainage matters too, because aubergines don’t like soggy roots.
3. Space Plants Properly
Give each aubergine plant about 18 to 24 inches of space so air can circulate around them.
Good airflow helps prevent fungal diseases, which aubergines can be prone to in humid conditions.
If you’re growing aubergines in pots, choose containers that hold at least 5 gallons of soil.
4. Water and Feed Regularly
Aubergines need consistent moisture, so water them deeply once or twice a week, depending on your weather.
Avoid letting the soil dry out completely, but don’t drown them either.
Feed your plants every couple of weeks with a balanced fertilizer once flowers start appearing.
This keeps them productive throughout the season.
Common Problems When You Grow Aubergines
Even when you know how do you grow aubergines, a few issues can pop up along the way.
Here are the most common ones and how to handle them:
1. Flowers Dropping Without Setting Fruit
This usually happens when temperatures are too cold or too hot, or when the plant is stressed.
Keep temperatures between 70°F and 85°F for the best fruit set.
2. Pests Like Flea Beetles and Aphids
Flea beetles love aubergine leaves, especially on young plants.
Row covers can protect them early on, and insecticidal soap helps with aphids.
3. Blossom End Rot
This dark, sunken spot on the fruit comes from a calcium imbalance, often caused by inconsistent watering.
Keep soil moisture steady and your aubergines should be fine.
So, How Do You Grow Aubergines?
You grow aubergines by starting them early indoors, keeping them warm, and giving them sun, water, and rich soil.
These heat-loving plants reward you with glossy, delicious fruit when you meet their basic needs.
Whether you’re growing aubergines in pots or a garden bed, the key is warmth, light, and patience.
So now that you know how do you grow aubergines, it’s time to get planting and enjoy your own homegrown harvest.
