Geum Borisii ground cover will die back to ground level in Winter and fresh new growth will appear in Spring. They are happiest in full sun, but all require moist but well-drained soil. They will not thrive in soil that becomes waterlogged. To maintain them simply cut back any tatty or brown foliage from the previous year in early Spring and divide any clumps that become congested in early Spring or late Autumn.
As a rough guide when planting Geum Borisii 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.
