Can You Keep Aubergine Plants Over Winter

Yes, you can keep aubergine plants over winter, and doing so is a great way to get a head start on next year’s harvest.
 
Aubergines are perennial in their native tropical climates, which means they naturally live for more than one year.
 
The problem is that they hate the cold, so in most temperate regions they’re grown as annuals and discarded once the frost hits.
 
But if you can protect them from freezing temperatures, your aubergine plants can survive the winter and produce fruit again the following season.
 
In this post, we’ll look at whether you can keep aubergine plants over winter, a few different methods for doing it, and the care they need to make it through to spring.
 
Let’s get into it.
 

Why You Can Keep Aubergine Plants Over Winter

You can keep aubergine plants over winter because they’re actually tender perennials, not true annuals.
 
Here’s why overwintering them works so well:
 

1. Aubergines Are Perennial by Nature

In warm, frost-free regions, aubergine plants live for several years and keep producing fruit season after season.
 
They only die back in colder zones because freezing temperatures damage their soft tissues.
 
So when you keep aubergine plants over winter indoors, you’re simply giving them the climate they evolved for.
 

2. Overwintered Plants Fruit Earlier

An aubergine plant that survives winter already has an established root system and woody stems.
 
That means it can focus its energy on flowering and fruiting instead of starting from scratch.
 
Gardeners who keep aubergine plants over winter often harvest weeks earlier than those who sow fresh seeds.
 

3. You Save Money and Seeds

Keeping aubergine plants over winter means you don’t have to buy new seeds or raise seedlings every spring.
 
A single healthy plant can reward you with another full season of crops.
 
It’s a simple, budget-friendly way to keep your garden productive year after year.
 

4. It Preserves Your Favourite Varieties

If you’ve found an aubergine variety that grows brilliantly in your garden, overwintering lets you keep it going.
 
You won’t lose those genetics to the frost, and you can even take cuttings from the parent plant.
 
That’s a big reason so many growers choose to keep aubergine plants over winter rather than replant.
 

How to Keep Aubergine Plants Over Winter

The method you choose depends on your climate and how much space you have indoors.
 
Here are the most reliable ways to keep aubergine plants over winter:
 

1. Bring Potted Plants Indoors

If your aubergines are growing in containers, this is the easiest option.
 
Before the first frost, move the pots to a bright, sunny windowsill or a heated greenhouse.
 
Aim for a spot that stays above 10°C (50°F) and gets at least six hours of light daily.
 

2. Take Cuttings in Late Summer

If you don’t have space for full-sized plants, you can keep aubergine plants over winter by taking cuttings instead.
 
Snip healthy, non-flowering shoots in late summer and root them in water or moist compost.
 
These small cuttings take up far less room and grow into vigorous plants by spring.
 

3. Dig Up and Pot Outdoor Plants

For aubergines growing in the ground, carefully lift them before the frost arrives.
 
Shake off the soil, trim the roots slightly, and pot them into fresh compost.
 
Then treat them like any indoor aubergine and keep them somewhere warm and bright.
 

4. Use a Greenhouse or Conservatory

A heated greenhouse or conservatory is ideal if you want to keep aubergine plants over winter without crowding your home.
 
Just make sure temperatures don’t dip below 10°C, and water sparingly to avoid rot.
 

Caring for Aubergine Plants in Winter

Once your plants are settled indoors, they need a slightly different routine to stay healthy.
 
Here’s how to care for aubergine plants you’re keeping over winter:
 

1. Water Sparingly

Aubergines grow slowly in winter, so they drink far less than they do in summer.
 
Let the top inch of compost dry out before watering again.
 
Overwatering is the quickest way to kill an aubergine you’re trying to keep over winter.
 

2. Give Them Plenty of Light

Short winter days can leave your plants weak and leggy.
 
Place them on the sunniest windowsill you have, or use a grow light for a few hours each day.
 
Good light is essential if you want to keep aubergine plants over winter and see them thrive.
 

3. Keep Them Warm

Cold draughts and sudden temperature drops can shock your plants.
 
Keep the room between 10°C and 15°C (50–59°F) and away from icy windows at night.
 

4. Prune Back Old Growth

Trim away dead leaves and any long, spindly stems before winter sets in.
 
This reduces pests and helps the plant conserve energy.
 
Don’t cut too hard though, since aubergines fruit on new growth from old wood.
 

5. Watch for Pests

Indoor warmth attracts aphids, whitefly, and spider mites.
 
Check the undersides of leaves regularly and treat any infestation early.
 
A quick rinse with soapy water usually does the trick.
 

So, Can You Keep Aubergine Plants Over Winter?

Yes, you can keep aubergine plants over winter as long as you protect them from the cold.
 
These tender perennials will happily survive indoors or in a heated greenhouse and fruit again the following season.
 
Just bring them in before the first frost, water sparingly, and give them plenty of light and warmth.
 
With a little care, the aubergine plants you keep over winter will reward you with an earlier and bigger harvest next year.
