What shrubs grow best in clay soil?

Many shrubs grow well on clay soils, especially the popular deciduous flowering shrubs: deutzia, philadelphus, weigela, forsythia and ribes for example. The level of nutrients in the soil means that supplementary feeding is rarely required for good flowering and performance.

4. Mulch beds over the winter.
5. Plant a cover crop.

What can I mix with clay soil for my garden?

What causes clay soil?
