Need to move stones, potted trees or bags of soil? Make your own sturdy garden dolly from a two-wheel hand truck and plywood. You can make the box any size you want (a box 31 in. wide will still fit through a doorway) and then attach it to your hand truck with U-bolts. It can handle a lot of weight and is easily removed. It’s also low to the ground, so you can just roll stones and other heavy items right into it without lifting.
