How to take care of Campanula Superba
Campanula Superba require moist well-drained soil (non-acidic soil). Place in an open sunny position but can tolerate partial shade. The larger border types such as the glomerata and punctate varieties are great for the border, and like full sun in a well-drained almost light alkaline soil.
Dead-head the plants after flowering by trimming them down to 1/3 of their height. Each spring apply an organic fertiliser to promote new and bushier growth. Divide clumps in autumn or spring.
