Are you a pepper enthusiast who wants to enjoy fresh peppers even during the colder months? Overwintering pepper plants is a great way to extend your harvest and continue enjoying the spicy goodness all year round.

In this comprehensive guide, we will walk you through the process of successfully overwintering your pepper plants, whether they are grown in pots or in the garden. By following these steps, you’ll be rewarded with a bountiful harvest of fresh peppers, even in November!

Overwintering your peppers outdoors

Keeping your pepper plants in the garden and allowing them to go into dormancy on their own can be a simple and effective method, especially if you live in a warmer climate with mild winter temperatures. When the nighttime temperatures start to drop below sixty degrees Fahrenheit, you’ll notice that the plant naturally begins to lose its leaves. As long as there is no frost, the plant should be able to survive the winter months.

This method of overwintering is suitable for regions where the winter temperatures don’t reach extreme lows and the plants can tolerate mild cold conditions. Here are some tips to successfully overwinter your peppers in the garden:

  1. Monitor the Temperature: Keep an eye on the nighttime temperatures in your area. Once they consistently drop below sixty degrees Fahrenheit, it’s a sign that the plants will naturally start to go into dormancy.
  2. Cease Fertilization: Stop fertilizing your pepper plants as the temperatures cool down. This will help signal to the plants that it’s time to prepare for dormancy.
  3. Reduce Watering: Adjust your watering schedule accordingly. As the plants enter dormancy, they require less water. Allow the soil to dry out slightly between waterings to prevent overwatering and root rot.
  4. Mulch the Soil: Apply a layer of organic mulch around the base of the plants. This will help insulate the soil and protect the roots from extreme temperature fluctuations.
  5. Protect from Frost: Keep an eye on the weather forecast and be prepared to cover your plants if frost is expected. Use blankets, frost cloths, or other protective coverings to shield the plants from freezing temperatures.
  6. Prune and Clean: Before the first frost, prune any dead or damaged foliage from the plants. This will help prevent the spread of diseases and pests during the dormant period.
  7. Monitor for Pests and Diseases: Even during dormancy, it’s important to keep an eye out for any signs of pests or diseases. Treat any issues promptly to prevent them from spreading or causing damage to the plants.

Transferring pepper plants indoors

If your pepper plants have been growing in pots, the process of transferring them indoors is relatively simple. However, if they have been growing in the garden, a bit more work is involved. But fear not, the rewards will be well worth the effort. Here’s how to do it:

  1. Choose the Right Pepper Plant: Select a pepper plant that has many buds and/or immature fruit. It’s also important to choose a plant that is not too large, as smaller plants tend to transplant better than larger ones.
  2. Prepare the Plant: Water or fertilize the plant a few days before the transfer to ensure it is fresh and strong for its journey indoors.
  3. Digging Up the Plant: Dig up the plant with a large root ball to minimize root disturbance. This will help the plant adapt better to its new environment. Place the plant into a pot that is big enough to accommodate it, such as a five-gallon bucket. Fill any empty spaces with extra soil and water the plant well.
  4. Give the Plants a Haircut: Since you have cut off some of the roots during the transplant, it’s important to balance the plant above and below the soil line. Trim the branches back or selectively cut off some branches while leaving others intact.
  5. Pest Control: Keep an eye out for pests, as bugs love to come indoors, especially aphids. Use an insecticidal soap mixture (4 tablespoons per gallon of water) to control them. Spray the plant foliage, covering both the tops and undersides of the leaves. Repeat this process every 3 to 4 days, 3 to 4 times, to ensure all pests are eliminated.

Bringing pepper plants outdoors after winter

After spending the winter indoors, your pepper plants may not look their best. However, with a little tender loving care (TLC), they will bounce back and start growing vigorously, producing fruit much earlier than newer transplants. Follow these steps to bring your pepper plants back outdoors:

  1. Pruning: Start by trimming back branches to give the plants a nice compact shape. This will encourage new branches to grow. If your plant is quite large, a more severe pruning may be necessary.
  2. Fertilizing: Begin fertilizing your plants a few weeks before moving them back outside. Use low levels of organic fertilizer to prepare the plants for their return to the outdoors.
  3. Acclimation: Gradually acclimate the plants to the outdoors by bringing them outside for short periods of time. Avoid exposing them to the sunniest and hottest part of the day during the initial trips outside.
  4. Potting Mix Replacement: If your plants will remain in their pots, remove as much soil as possible without disturbing too many roots. Replace it with fresh potting mix that contains nutrients. Fertilize with organic fertilizers once a week for the first three weeks, then every two weeks thereafter.
  5. Transplanting to the Garden: If you plan to transplant your overwintered pepper plants back into the garden, wait until the ground and air have warmed up. Dig a hole beforehand and have it ready to go. Carefully remove the plant from its pot and plant it in the prepared hole. Tamp down the soil gently after planting. Fertilize immediately with an organic fertilizer and continue fertilizing every week for the first three weeks, then every three weeks thereafter.

Frequently Asked Questions (FAQ)

Can I overwinter any type of pepper plant?

Yes, you can overwinter most types of pepper plants, including bell peppers, jalapenos, habaneros, and more. However, it’s important to choose a healthy plant with buds or immature fruit for the best results.

How do I prevent pests from infesting my pepper plants indoors?

Bugs, especially aphids, can be a common problem when bringing plants indoors. Use an insecticidal soap mixture (4 tablespoons per gallon of water) to control pests. Spray the plant foliage, covering both the tops and undersides of the leaves. Repeat the process every 3 to 4 days, 3 to 4 times, to ensure all pests are eliminated.

Can I overwinter pepper plants in a greenhouse?

Yes, you can definitely overwinter pepper plants in a greenhouse. In fact, a greenhouse provides an ideal environment for overwintering plants, as it offers protection from frost and allows for better temperature control. Follow the same steps mentioned earlier to transfer your pepper plants into the greenhouse and provide them with the necessary care throughout the winter months.

How long can I expect my overwintered pepper plants to continue producing fruit?

With proper care and maintenance, overwintered pepper plants can continue producing fruit for several months. The exact duration will depend on various factors such as the plant’s health, growing conditions, and the specific pepper variety. It’s not uncommon for overwintered pepper plants to produce fruit well into the following year.

Are there any specific tips for overwintering pepper plants in colder climates?

If you live in a colder climate, there are a few additional steps you can take to protect your overwintered pepper plants. Consider insulating the pots or containers with straw or bubble wrap to provide extra insulation. You can also use frost blankets or row covers to shield the plants from freezing temperatures.

Additionally, placing the plants near a south-facing window or using supplemental grow lights can help provide them with sufficient light during the shorter winter days.


Overwintering pepper plants is a rewarding endeavor that allows you to enjoy fresh peppers throughout the year. By following the steps outlined in this guide, you can successfully transfer your pepper plants indoors, provide them with the necessary care during the winter months, and bring them back outdoors in the spring.

Remember to monitor for pests, provide adequate fertilization, and gradually acclimate the plants to their new environments. With a little effort and patience, you’ll be rewarded with a bountiful harvest of fresh peppers, even during the colder months. Happy gardening!
