i have a customer who unfortunately got ripped off. he is the head of the hmo and he paid a landscaper to mulch an area aprox 80sq feet around the entrance sign with a grey mulch but what he got was 4 inches of shredded bark! and he placed it on top of two inches of old mulch. now i need to try to figure how to remove all the bark and mulch with minimal damage to the existing trees bushes and flowers. any ideas? thanks
