How do I overwinter a plumbago? I live in the Northeast.
Plumbagos, deciduous shrubs with beautiful blue flowers, are generally grown indoors in the Northeast. These flowering shrubs can reach 18 feet tall. The ideal overwintering conditions are in greenhouses with temperatures from 45 to 50 degrees Fahrenheit. To keep a plant going over the winter, whether you have a greenhouse or not, be very careful with watering. Let the soil dry out almost completely between waterings, then give it a good soak. Don’t prune the plant until February or March, and remember that plumbagos like to spread horizontally, so plant them 18 inches deep and in a space 2 to 3 feet across.
