Can You Keep Aubergine Plants Over Winter

Yes, you can keep aubergine plants over winter, and with the right care, they’ll reward you with a head start next season.
 
Aubergines are perennial plants in their native tropical climates, so they naturally want to keep growing year after year.
 
The challenge is that they hate the cold, and most gardeners treat them as annuals simply because frost kills them.
 
But if you can protect them from freezing temperatures, keeping aubergine plants over winter is absolutely doable.
 
In this post, we’ll look at whether you can keep aubergine plants over winter, how to do it successfully, and what to expect from your overwintered plants.
 
Let’s dig in.
 

Can You Keep Aubergine Plants Over Winter?

You can keep aubergine plants over winter, but it takes some planning and a bit of patience.
 
The key is understanding what aubergines need and recreating those conditions indoors or in a protected space.
 
Here’s why keeping aubergine plants over winter works and what you need to know:
 

1. Aubergines Are Tropical Perennials

Aubergines originated in warm regions of Asia and Africa, where they grow as short-lived perennials.
 
In those climates, aubergine plants keep producing fruit for two or even three years.
 
The only reason we treat them as annuals is because they can’t survive a frost.
 
So when you keep aubergine plants over winter, you’re actually letting them live out their natural lifecycle.
 

2. They Go Dormant, Not Dead

When temperatures drop and daylight fades, aubergine plants slow their growth dramatically.
 
They don’t die back completely like some perennials, but they do enter a semi-dormant state.
 
During this time, they need far less water and no fertilizer.
 
This dormancy is what makes keeping aubergine plants over winter possible indoors.
 

3. A Head Start Next Season

An overwintered aubergine plant already has an established root system.
 
That means it can start fruiting weeks earlier than a plant grown from seed.
 
If you keep aubergine plants over winter successfully, you’ll often get your first harvest a month sooner.
 
For short growing seasons, that head start is a game changer.
 

How to Keep Aubergine Plants Over Winter

Keeping aubergine plants over winter isn’t complicated, but it does require consistency.
 
Here’s how to keep aubergine plants over winter step by step:
 

1. Move Them Indoors Before Frost

Aubergine plants need to come inside before the first frost hits.
 
Even a light frost can damage the leaves and stems beyond recovery.
 
Aim to move your plants indoors when nighttime temperatures start dipping below 50°F (10°C).
 
If you keep aubergine plants over winter in a greenhouse or conservatory, that works too.
 

2. Pick a Bright Spot

Light is the biggest challenge when you keep aubergine plants over winter indoors.
 
These plants still need several hours of bright, indirect light each day, even while dormant.
 
A south-facing windowsill or a spot under grow lights works well.
 
Without enough light, aubergine plants over winter will stretch, weaken, and struggle to bounce back.
 

3. Cut Back on Watering

Overwatering is the number one killer of aubergine plants kept over winter.
 
Since growth has slowed, the roots use very little moisture.
 
Let the top inch of soil dry out completely before watering again.
 
If you keep aubergine plants over winter too wet, the roots will rot fast.
 

4. Skip the Fertilizer

Don’t feed your aubergine plants over winter.
 
Fertilizing encourages new growth, which the plant can’t support with limited winter light.
 
Wait until early spring, when you see fresh signs of life, before feeding again.
 
That way, aubergine plants kept over winter save their energy for the season ahead.
 

5. Watch for Pests

Indoor conditions are paradise for spider mites, aphids, and whiteflies.
 
Check the undersides of leaves regularly when you keep aubergine plants over winter indoors.
 
Wipe leaves with a damp cloth or treat infestations early with insecticidal soap.
 
Healthy aubergine plants over winter are far less vulnerable to pest problems.
 

Tips for Success When You Keep Aubergine Plants Over Winter

A few extra tricks make keeping aubergine plants over winter much easier:
 

1. Prune Before Bringing Them In

Trim back leggy stems and remove any yellowing or diseased leaves before the move indoors.
 
This reduces pest hiding spots and helps the plant focus energy on survival.
 
A good prune also makes aubergine plants over winter easier to manage in tight spaces.
 

2. Repot If Needed

If your aubergine is in a small pot, consider moving it into a slightly larger one before winter.
 
Fresh potting mix gives the roots room and nutrients to hold onto through the dormant months.
 
It also helps you keep aubergine plants over winter without the soil turning sour.
 

3. Gradually Reintroduce Them Outside

When spring arrives, don’t rush your plants back outdoors.
 
Harden them off slowly over a week or two, starting with a few hours of shade each day.
 
This prevents shock and gives aubergine plants kept over winter the best chance to thrive again.
 
Your patience through winter pays off with stronger, earlier-producing plants.
 

So, Can You Keep Aubergine Plants Over Winter?

You can keep aubergine plants over winter, and doing so gives you a jump on the growing season.
 
With bright light, minimal water, and no fertilizer, aubergine plants over winter will stay alive and ready to grow.
 
Just remember to bring them in before frost, watch for pests, and be patient during their dormant phase.
 
If you follow these steps, keeping aubergine plants over winter becomes a simple yearly habit that rewards you with earlier harvests and healthier plants.
