There is no garden HAHAHA When we bought the house the backyard was empty...just dirt, few patches of grass, and weed/dead small trees. The previous people who were renting from the owner of the home really trashed the place and their dog ripped the sprinkler system out..we had to really get down and do some cleaning before we moved in 
IDK what else to use it for but it can either be an addition to the dirt or I can just wash the hell outta it and let it dry and reuse it for my plants (indoor plants) and the tortoise seed mix I have..feels like a waste because I used alot of substrate for the previous tort I had and mixed it with sand and that tort was sick so all that bedding can't be reused so maybe it'll add to the dirt in the back hahaha
