These plants have been selected because their preferred growing condition is clay soil. By using plants that are naturally adapted to these conditions, we can reduce the potential problems that are more likely with plants that are less well suited.
The Ajuga and Geranium provide some ground cover and will help prevent erosion of bare soil. The ground cover can also help to reduce moisture evaporation from the soil surface and suppress weed growth in summer.
Until the plants have filled out, an organic mulch, preferably homemade compost, can help to lock in soil moisture and suppress weeds. Mulches should be spread when the soil is already moist to help trap some of that moisture before it dries out in summer.
