You are all welcome. For the last 5 years, I have been getting about 32 yards of mill sawdust (1/4inch wood chips) every year.
It has a little bit of horse manure mixed in. Its free, but I have it delivered which cost $20. This stuff works wonders when spread on top of the soil. The first year, I made the mistake of tilling it into the soil, and it sucked up the nitrogen. Leaves of plants turned yellow. Spread about 6 inch thick around my veggies, and never water all summer, which is hot and dry where I am. I spread to the drip line under my fruit trees, and never water.
