Hi all, I put down a layer of hay on my community garden plot in the fall. Covered up all the bare ground, and put it around the crowns of the asparagus & rhubarb. This spring, I went out to check on the garden & lo & behold, the soil underneath the hay mulch was soft, friable, beautiful stuff. Not packed down at all. Looking at other plots in the community garden, I could see the difference my mulch made. So here is my question. Should I keep a light layer of mulch on the garden & just plant seeds & transplants underneath it? To keep the soil from getting compacted? (Soil has a lot of clay). Also, I expected the hay to be decomposed or at least partially decomposed. It is not at all. What will happen if I put a 4 " layer of compost on top of it? or a 6" layer? Will I just be providing great growing conditions for all those hay seeds? Should I put down a lay of cardboard first? I am trying to do no till gardening.
