Look at my friends! They are serving their community by doing a bit of lasagna gardening. The process involves peeling off all tape and labels from strictly brown cardbaord. Then you lay it down over the grass/weeds you want dead. Then you wet it down with a hose and cover it with three inches of mulch made out of chicken poop. You wet it all down one last time. It is biodegradable as compared to the black fabric others choose to use to kill/block weeds. We learned a lot, worked hard, and were treated to a free bird show at tracy aviary. Good times!
