Your pepper plant should be allowed to go dormant during the winter months. Remove all of flower buds and leaves when you cut them down in fall or if new leaves and buds form during the dormant period. Removing the leaves will reduce insect pests. Decrease the water in fall and winter so the plant goes dormant. A dormant pepper plant still needs a little light. Grow the pepper plant in a cool location that is above 50 F. Only give the plant a a small amount every 3-4 weeks. Most plants in MN need less water during the winter because they are not actively growing.
