Answer: The best thing you can do for a clay soil is to add composted organic matter, which will improve the structure and internal drainage and aeration of the soil. Do this any time you plant or replant a garden bed. Add a couple of inches of compost and work it in deeply. Or, you might consider building raised planting beds and fill them with 3 way top soil which will contains organic matter and sand. These materials will not only make the soil easier to work but will also improve drainage.
Good luck with your garden!
