If it were a larger area I'd suggest purchasing a bulk load of 3-way mix (topsoil, compost and sand). Since the area is a little small for that, you can mix your own soil. You can use a wheelbarrow or other large container where you can readily mix together one part garden soil, one part organic matter (compost, peat moss, well-rotted manure), one part vermiculite or perlite, one part builder's sand, and 1/2 cup of fertilizer (5-10-5, 6-10-4, or a similar fertilizer formulation). Mix together well, dump into the bed and mix together with the clay soil. Make as many batches as necessary to fill the bed within a few inches of the top. If you cannot find large bags of vermiculite or perlite you can substitute bags of potting soil (which contain a large percentage of these elements).
