I have a customer that has hired me to do a weed control application of Snapshot in some relatively bare landscape areas. Before I apply the Snapshot I want to turn over the hardwood mulch that has become matted over the winter. I am looking for the best way or tool to turn over those mulch beds. Each bed has minimal plantings and for the most part and are wide open. There are three of them and each one is about 1500 sf for a total of 3500. Which method or tool would work best for turning them over. FYI, I will be doing the work myself. I have considered a steel rake and a strong back, I have also considered using a power rake set to a shallow depth or possibly a tool like a Garden Weasel. Any suggestions would be greatly appreciated.
