Answer: You can build your own sandy loam by incorporating lots of organic matter into your clay soil. You can use compost, aged manure, shredded leaves, rice hulls or whatever organic matter is locally available. Spread 4-5 inches of organic matter over your soil, plus a quarter to a half inch of builder's sand, and till it in to a depth of 8-10 inches. Level the soil and plant your veggies, then cover over the bare soil with additional organic matter. This mulch will help suppress weeds and slow water evaporation.
At the end of the season dig this mulch into the soil and spread another couple of inches of compost or manure over the entire bed. If you dig the mulch in every year you will eventually build your own sandy loam. You can purchase compost and builder's sand in bags at your local Home Depot.
