For many years in my area of town, we were not allowed to burn yard waste. My trash carrier did not pick up yard waste. What's a girl to do? I started a branch pile behind a tree in the back corner of the yard. Years of pruning, chopping down 3 small trees, and general tree and bush maintenance left a pile that was over my head. One weekend, we rented a wood chipper and ground it all down to mulch. The red arrows show the size of the original pile. A couple of loud, dusty hours later, we had had a knee-high pile of mulch, which is now spread on the flower beds.
