Heavy potted plants are easily moved with a homemade dolly. Begin by finding a flat stone that is large enough to hold the pot. Cut a piece of 3/4-inch-thick exterior plywood into a square just smaller than the stone. Stain the plywood to match the stone's color, and attach four casters to the bottom. Set the stone on the plywood and the pot on the stone. Hold the pot when moving to avoid tipping.
