London, United Kingdom
I have two sedums (iceplants) in the garden. This time of year they have purple flowers, so they bring colour to the garden, and I know they are also good for wildlife. In spring they are a pleasing domed shape but they quickly grow upwards and outwards until they collapse and there is a hole in the middle while they swamp the plants around them! Is there anything I can do to prevent them from collapsing?
