Super low maintenance, as a ground cover plant Geranium Johnsons Blue (Cranesbill) will tolerate any soil other than waterlogged areas and will be happy in full sun or partial shade. In midsummer rejuvenate plants that are beginning to look jaded, by removing old, flowered stems and leaves, and split the clumps in spring if they are getting too large.
As a rough guide when planting Geranium Johnsons Blue as ground cover – 4 plants per square metre is adequate with a little patience, 6 will give better coverage, and 9-12 will make a weed supressing carpet very quickly.
