I started a rock garden of sorts this past year... I paid this guy $100 to bring a load of rocks. He had a bobcat and was able to move them around for me. I think moving the rocks around is the biggest challenge. The bigger they are the harder they are to move! U can hurt yourself if u are not careful.
Right now i'm not happy with my pitiful rock garden. I think i placed the rocks okay, but i'm not satisfied with what i've got planted. It really takes some imagination to place the rocks in a way that makes it look natural instead of fake. I wanted the rocks to look like they were there all along. Hopefully, this coming year i can improve upon what i started!
