I've lost 3 of these plants over the last 2 years, the latest one dying on me recently when it was planted out last year and seemed to establish. There are other alpines in this planting area, but they have all survived well. The soil is on the sandy side so it is free draining and the site is west facing in full sun from midday. The soil can get quite dry in a warm/hot summer. I've no idea why the Campanula has been suffering as I thought they can grow happily in gravel. Any ideas please?
