How to Care for Calibrachoa in Winter

Updated February 21, 2017

Calibrachoa is a relative of the petunia that produces blossoms of white, yellow or shades of pink. The plant is an annual, meaning it only lasts one growing season and usually dies during the winter. Though it may survive outdoors during very mild winters, the easiest way to ensure its survival over winter is to bring it inside.

  1. Bring the calibrachoa inside if it is in a container and place it in a cool room, such as a garage, with good air circulation. Bring it indoors before the first frost.

  2. Dig around the base of the calibrachoa, if your plant is in the ground. Dig under the bottom of the calibrachoa so you don't cut any of the roots. Fill a potting container halfway with potting soil and transfer the calibrachoa into the pot. Fill the pot the rest of the way and firm it with your hands.

  3. Bring the pot inside to a cool room or garage. Put it in a spot where it will get between four and six hours of sunlight daily. Water the plant until the liquid comes out of the drainage holes. For the rest of the winter, give the calibrachoa a weekly watering of the same amount.

  4. Apply a general purpose fertiliser to the soil once a month for the remainder of the winter, according to the directions on the package.

  5. Use sharp scissors to cut back any new, thin or leggy stems that sprout.

  6. Move the pot to a warmer room as the temperatures climb above freezing. Increase watering to twice a week until the last frost passes. You can then transplant the calibrachoa back into the ground or move the pot outside.
