Overwintering Peppers Update

Overwintering peppers is a fantastic way to save your favorite plants, extend their lifespan, and get a head start on the next growing season. If you’ve been following my previous posts on overwintering peppers, you’ll know that the process involves bringing pepper plants indoors before the first frost, pruning them back, and providing the right conditions to keep them alive through the winter. Now that we’re well into the colder months, it’s time for an update on how my overwintered peppers are doing, what’s working, and what challenges have arisen.

How the Plants Are Holding Up

This year, I decided to overwinter four pepper plants: two habaneros, one ghost pepper, and a sweet bell pepper. After bringing them inside in late October, I pruned them down to about 8-12 inches in height, removing most of the leaves to reduce stress on the plants and minimize pest risks.

Growth Observations

• Habaneros: These have been the most resilient. Both plants have started putting out new growth, with small leaves emerging along the stems. One has even developed tiny flower buds, which I’ll likely pinch off to encourage stronger vegetative growth before spring.
• Ghost Pepper: This one was slower to bounce back but is now showing new shoots near the base. The stems remained green and healthy, a good sign that it’s still alive and just taking its time.
• Bell Pepper: Surprisingly, this one struggled the most. It dropped nearly all its leaves after pruning and has been very slow to regrow. However, the stems are still flexible and green, so I’m hopeful it will recover with time.

Lighting and Temperature Conditions

Since peppers are tropical plants, they need adequate light and warmth even in dormancy. Here’s what I’ve been providing:

• Light: I’m using a basic LED grow light (about 20W) positioned about 12 inches above the plants, running for 12 hours a day. This seems sufficient to prevent leggy growth while not overstimulating them.
• Temperature: They’re kept in a room that stays between 60-70°F (15-21°C). Cooler temperatures slow growth, which is fine for overwintering, but anything below 50°F (10°C) can be risky.
• Humidity: Indoor heating can dry out the air, so I’ve placed a small humidifier nearby and occasionally mist the plants to prevent leaf drop.

Watering and Feeding Adjustments

Overwatering is the biggest killer of overwintered peppers. Since their growth slows or stops, they need far less water than in the growing season.

• Watering Routine: I’ve been watering only when the top 1-2 inches of soil are completely dry—about once every 10-14 days.
• Fertilizer: I’ve held off on fertilizing entirely. Dormant or slow-growing plants don’t need extra nutrients, and fertilizing now could lead to salt buildup in the soil. Come late February or early March, I’ll start with a diluted balanced fertilizer to encourage new growth before transplanting outside.

Pest Watch

Indoor peppers can attract pests like aphids, spider mites, and whiteflies. Unfortunately, I did notice a few spider mites on one of the habaneros a few weeks ago.

• Treatment: I sprayed the plant with a mix of water, mild soap, and a little neem oil. After two treatments a week apart, the infestation was under control.
• Prevention: Regularly inspecting leaves (especially undersides) and keeping humidity up helps deter pests. Isolating new plants before introducing them to the overwintering area is also key.

Next Steps: Preparing for Spring

As we move closer to spring, here’s the plan for transitioning the peppers back outside:

1. Gradual Pruning (Late February): If the plants have become leggy, I’ll do another light pruning to encourage bushier growth.
2. Increasing Light (March): I’ll extend the grow light duration to 14-16 hours per day to mimic longer daylight hours.
3. Hardening Off (After Last Frost): Once nighttime temperatures stay above 50°F (10°C), I’ll start acclimating the plants to outdoor conditions by placing them outside for a few hours each day, gradually increasing exposure over a week or two.
4. Repotting (If Needed): Some plants may need fresh soil or larger pots before going back into the garden.

Final Thoughts

Overwintering peppers isn’t always perfect—some plants thrive while others struggle. But even if only half make it, that’s still a head start on the next season! The habaneros are looking strong, the ghost pepper is hanging in there, and the bell pepper… well, we’ll see. The key takeaways so far:

• Less water is better – Overwatering is the #1 issue.
• Watch for pests – Indoor plants are pest magnets.
• Patience pays off – Even slow growers can bounce back.

I’ll post another update in early spring as these peppers (hopefully) gear up for another productive season. If you’re overwintering peppers too, how are yours doing? Any tips or challenges to share?
