Tips For Keeping Your Pepper Plants Alive Over The Winter

Tips for Keeping Your Pepper Plants Alive Over the Winter

News and Info |

If you don’t want to hassle with seed-starting in the spring, or if you have a particular pepper plant you love, try overwintering it and you’ll have more peppers earlier in the season. With a little pepper winter care indoors, you can keep your pepper plants alive through the winter frost. If your peppers are in the garden, vs in containers, you will have to dig them up, plant them in a container and bring them indoors. If you plan on overwintering pepper plants, realize that this will keep the plant alive, but it will not produce fruit. To produce fruit, peppers need higher temperatures and greater amounts of light than the average US homes can provide in the winter. Overwintering peppers isn’t overly complicated, but below are a few tips to make the process successful.

Note: if you live in a warmer climate that does not have frost and doesn’t get too cold, your plants should be fine outside over the winter. I’m in Southern California and I leave my container grown plants outdoors all winter. I simply water them every now and then, and they are ready to pick up right where they left off once Spring rolls around.

For places that do encounter frost, here are the steps to keep those plants alive.

Step #1: Bring Your Pepper Plant Inside

The first step to overwintering your pepper plants is to bring them indoors before first frost. Before you do so, thoroughly spray down the entire plant, including the roots. This will help remove any pests that may be hiding on the leaves or roots. Remove all pepper fruits, mature or immature, from the plant.

If you are transplanting a pepper plant from the garden to a container, dig up as many roots as possible. This will help your plants soak up nutrients and moisture from the soil come spring, when are replanted into the garden and attempting to regain their strength. USE POTTING SOIL when transplanting. Tempting as it might be to use your garden soil to pot up your overwintering peppers, don’t do it. Garden soil is full of pests, and once the soil warms up inside, those pests will be all over your house. Instead, use fresh potting soil when moving your plants into pots.

Step #2: Location, Location, Location

There are two places you can put your overwintering peppers once you bring them inside. The first option is a cool, dark basement area that receives minimal light. This setting will force the plants into dormancy, meaning alive but not actively growing. They might look dead, but they are not. During this period of dormancy, you’ll want to make sure the soil doesn’t get too wet or too dry. Give the soil a nice spritzing every once and awhile so it stays lightly moist.

The second place you can put your pepper plants is in a sunny window or under grow lights. In this case, they may not become dormant, but they most likely will not produce fruits until Spring. Give them a bit more watering than the fully dormant plants located in a dark basement.

Step #3: Cut back on watering

Once you have placed the pepper plant in this location, cut back the watering. When you are keeping peppers over the winter, you will find that they need far less water than in the summer. You should only need to water the plant once every three to four weeks. Do not let the soil stay soaked, but also do not let it dry out completely.

Shortly after you place the pepper in a cool location and cut back watering, you will notice the leaves starting to die back. Don’t panic, this is normal. The pepper plant is entering dormancy.

Step #4: Prune your pepper plants

Once the leaves start to die, you can prune back the pepper plant, meaning trimming the plant to remove any injured or dead branches. Prune the branches of the plant to a few main Y’s on the plant, leaving about 1 to 2 in. for the upper part of the Y. This step will remove the dying leaves and make the plant less susceptible to pests. The pepper plant will grow new branches in the spring.

Step #5: Prepare for Spring

To finish your pepper winter care, about a month before your last frost date, bring your pepper plant out of the cool location and move it to a brighter, warmer location. You may even want to use a heating pad under the pot to add additional heat. Resume watering, but make sure not to over water the pepper plant. In a week or so, you should see some new growth appear.

I’ll be honest, even if you follow all of the steps for how to keep peppers alive over winter, you may find that your pepper plant does not survive.  😭

When overwintering pepper plants, some varieties do perform better than others. For example, I had a great habanero plant that would not quit, it actually produced fruit all winter. And my Brazilian Starfish plant just insisted on growing like crazy even though I left it outside over the winter and gave it very little water. I’d bet that the superhot varieties might be more difficult to overwinter.  When overwintering goes in your favor, you can enjoy your favorite peppers earlier in the season with a bit less work.
