We've only been in Buckley for 6 months and are starting our first garden. When we went to the local nursery she spoke of "Buckley Muck" but we didn't say anything because we didn't know exactly what she meant. Well.. WE DO NOW! It tills up as beautiful black soil but it is sticky, especially when wet. When it dries, there are big clods that have to be broken up. We've been putting some of it throug a sifter and it gives us beautiful looking soil. We have not tested the soil but have had good luck with the plants we put out under caps of some sort. Corn inabout 13" high in a kloshe. Tomatos, Walla Walla Sweet Onions, brocchli, zucchini and cukes are looking good. I've used Miracle Grow per instrucions for veggies.

My question: Is there something we should be adding to this Buckley Muck to help it not be so sticky? Never have seen dirt quite like this. Thanks/Shira
