Without some intervention, clay soils can be like concrete in summer and a sticky mess in winter. Any effort to improve the texture of clay will be rewarded with strong plant growth. This soil is rich in nutrients and will happily accommodate a considerable range of plants.
When planting on heavy clay soil it is always advisable to attempt some improvement of the soil, by working in organic matter. Mulching the surface of the soil will also help improve the texture.
