Plants For Clay Soil

Clay soil is usually rich in nutrients, but it can be hard to dig, and if it is very heavy, it can hold water for long periods of time. It may also take a long time to warm up in spring, which can slow down the new growth. If your clay soil is badly compacted, you can help improve the structure by digging in lots of sharp sand and composted organic matter.
