I hunt on the ground sometimes and have harvest deer. I know it's not as good as being up ina tree but you do get lucky on the ground too. I don't even have camo on ( black shirt and blue jeans) once and shot a doe at 30 yards. If you have the funds yes get yourself a good camo clothings. When I'm on the ground I just stand behind big trees or make a half blind with branches and try to blend in as good as possible.
