Did you know pepper plants are actually perennials?
In warm climates, they can live and produce for multiple years. But in most parts of the country, frost puts an end to the growing season. The good news? You don’t have to say goodbye to your favorite plants every fall.
Overwintering allows you to bring your peppers indoors, let them rest through winter, and wake them up stronger in spring.
Here’s everything you need to know.
Why Overwinter Pepper Plants?
Overwintering isn’t just about saving a plant, it’s about gaining an advantage.
🌱 Earlier Harvests
Established root systems wake up fast in spring. Instead of starting from seed, your plant already has a mature foundation, which means earlier flowering and fruiting.
🌶️ Preserve Special Varieties
Super hots and rare varieties often take longer to ripen. Overwintering saves you from restarting that long timeline.
⏳ Save Time & Resources
No re-buying seeds. No waiting for seedlings to catch up. Your plant simply picks up where it left off.
💡 Bonus: Keep Them Producing Indoors
If you have strong grow lights and a warm setup, some pepper plants can continue producing indoors through winter. Just be vigilant about pests.
When Should You Start Overwintering?
Start the process when overnight temperatures dip into the mid-40s°F (around 7°C).
You’ll likely notice:
-
Slower growth
-
Leaf drop
-
Reduced flowering
That’s your cue. Don’t wait for frost - frost will damage or kill the plant.
Step-by-Step: How to Overwinter Peppers
1️⃣ Choose Your Best Plants
Select your healthiest, most productive plants. Focus on:
-
Strong stems
-
No major pest issues
-
Good overall vigor
Super hots and long-season varieties benefit the most.
2️⃣ Prune Them Back
Trim branches back significantly, leaving a few nodes on the main stem. These nodes are where new growth will emerge in spring.
Remove:
-
All leaves
-
Any remaining fruit
It may look dramatic but this pruning helps the plant conserve energy during dormancy.
3️⃣ Dig, Clean & Repot
Carefully dig up the plant, keeping the root ball intact.
Then:
-
Shake off excess soil
-
Rinse roots gently with lukewarm water
-
Trim damaged or overly long roots
-
Repot in fresh, well-draining soil
💡 Pro Tip: A quick dip in mild insecticidal soap can help prevent bringing indoor pests along for the ride.
4️⃣ Store in a Cool, Dry Location
Place your plant in a cool area around 55–60°F (13–15°C).
This cooler temperature:
-
Slows growth dramatically
-
Encourages dormancy
-
Reduces water needs
Water sparingly. Keep the soil slightly moist, but never soggy. Overwatering is the most common mistake during dormancy.
What Happens During Winter?
Your plant may:
-
Drop more leaves
-
Look bare or “lifeless”
-
Show little to no growth
That’s normal. It’s resting, not dead.
As long as the stem remains firm and not mushy, your plant is alive.
Waking Them Up in Spring
When outdoor temperatures consistently warm up:
-
Move plants to a brighter area indoors.
-
Increase watering slightly.
-
Once frost danger has passed, gradually reintroduce them to outdoor sunlight (a process called hardening off).
Within a few weeks, you should see fresh green growth emerging from those nodes you left behind.
Common Overwintering Mistakes
-
❌ Waiting until after frost
-
❌ Overwatering during dormancy
-
❌ Skipping pest inspection
-
❌ Keeping plants too warm without enough light
If kept too warm without sufficient light, plants may become weak and leggy instead of dormant.
Is Overwintering Worth It?
For many pepper growers, especially super hot fans, absolutely.
Instead of starting from scratch, you’ll begin the season with a mature plant that’s weeks (sometimes months) ahead of seedlings.
More growth. Earlier harvests. Bigger yields.
And best of all? You get to keep growing your favorites year after year.
