Campanula encompasses a wide range of species, which includes perennials, biannuals, and annuals. Heights vary from inches to four to six feet tall. All of the many varieties are extremely hardy and can be found in cottage gardens, rock gardens, and borders. Campanula are also known as bellflowers. They are low maintenance plants, making them wonderful plants for your garden. You will need to prune to remove any diseased plant material, to deadhead, and to winterize.
Remove any diseased plant material as soon as possible. Do not place any diseased plant material in your compost bin--dispose of it. Disinfect the blades of your pruning shears after pruning diseased plant material by dipping the blades in either bleach or alcohol.
Deadhead the spent blossoms of campanula by pinching off the flower head when it dies. If you want the plant to reseed itself, then do not deadhead. Another option is to save some of the deadheaded blossoms, dry them out, and use the seeds for growing additional plants.
Prune back the plant stems anywhere from two to four inches from the ground after the first hard frost. Place the dead plant material in your compost bin.
Mulch the plant bed by covering it with leaves (which are readily available in the fall), hay, straw, or evergreen boughs to winterize.
Things You Will Need
- Hand pruning shears
- When winterizing do not cut back the plants too early as this may promote growth. Promoting growth at this time will cause the plant to use up its stored energy, which it needs to survive the winter.
