Although it makes for a longer mowing time, I've started bagging all the grass clippings from the yard around the house and depositing the waste in the vegetable garden that is to be.
Each small wagon load holds about 10 bags of clippings. A full bag weighs about 15 pounds. I estimate I've put at least 25 wagon loads of dead grass on the garden this summer or about 3750 pounds. The dead grass is rich with 10-10-10 fertilizer and it adds much-needed organic matter to the dirt.
I've spent so much time and energy getting the garden plot ready that the first radish that grows there will seem anti-climactic.
