Timing depends on local frost dates, weather and the particular plant or task. Clay soil can hold nutrients well but compacts when worked wet. Add organic matter as a surface mulch and avoid digging when waterlogged. Choose plants suited to moisture conditions and improve drainage gradually. In colder areas, wait until conditions are suitable rather than relying on a calendar date alone.
