Overwintering Pepper Plants:  How to Save Your Favorite Pepper Plants for 2018

The first step is to bring your pepper plant indoors.  Pick your best producing and strongest plants to bring indoors.  Find a pot that will fit a good-sized root ball, approximately the same size of the pot you’ve chosen.  I chose an 8” pot that is about 6” deep.  Gently cut a circle around your pepper plant with your shovel and then lift.  Try not to disrupt the root ball as you transfer it to your new pot.  Then fill in the pot as needed.  Make sure you spray the plant down with Captain Jack’s dead bug or safe soap.  You don’t want to bring in spider mites or any other unwanted insect.

It is suggested that you keep your plant in a nice cool spot (~55 oF), such as the garage or basement.  My garage is not heated and will get way below 55 oF over the winter.  I just keep my pepper plant upstairs by the window with all my other house plants.  The biggest issue I have with keeping my pepper plant indoors has to do with watering.  Other gardeners say if you keep your plant in a cool place, you won’t need to water it except for every 3-4 weeks.  However, I find that my house tends to run dry over the winter.  I need to water it every several days just to keep it from drying out completely.

Sometime in the spring, your plant will begin growing new branches.  The plants take their queue from the length of sunlight per day.  Your plants naturally know when it’s time to start growing.  At this point, make sure you are watering your plant regularly.  Make sure you don’t over water it.  Outdoor soil is dense without the worms for aeration.
