Determine how large you want the succulent wall hanging to be. You can make one large wall piece, for example, or several small pieces spread around a room.
Measure the dimensions necessary to create the frame onto a two-by-four. For example, if you want a 24-by-24-inch succulent wall frame, measure four 24-inch increments on a two-by-four using a tape measure. Mark each increment using a pencil, then cut them with a table or hand saw.
Place the boards together on a flat surface so they form a square or rectangle, depending on whether or not each side is the same length. Screw the boards together with two wood screws on each corner using a drill and Philips-head drill bit.
Cut a piece of ¼-inch plywood to fit the dimensions of your frame. For example, if the frame is 24 inches by 24 inches, cut a square of plywood that is also 24 inches by 24 inches. Place the plywood into the frame and screw it in place using wood screws and a drill.
Lay a screen over the open part of the frame; you can use either a plastic or metal screen with ¼-inch squares. Staple the screen to the frame, then trim the excess with a pair of wire cutters.
Pour cactus soil onto the screen. Break the soil up with your hands, then shift the frame back and forth to work the soil into the box. Repeat this process until the soil reaches the screen.
Place succulent cuttings into the squares in the screen; their stems should be at least ¼ inch long. Arrange the succulent cuttings so that they touch and fill the frame. If the succulents are freshly cut, let them dry until the stems form a "callus," which is a piece of skin over the cut end of the stem.
Leave the frame in a flat location for a week or two, allowing the succulents to form roots. Test the succulents for roots by tugging them gently. They are rooted if they feel fixed in place. Pour water onto the succulents once the roots have formed.
Screw a wall hook into the wall where you want to hang the frame. Ensure you screw the hook into a stud, which is a board behind the drywall. Knock on the wall while listening carefully; a stud is located in the spots where you hear a solid, dull "thunk" sound.
Pound two nails side-by-side into the back of the frame so that they protrude ¼ inch; they should be spaced one-third the width of the frame. For example, if the frame is 15 inches wide, the screws should be placed 5 inches apart.
Tie a piece of rope to the two nails on the back of the succulent frame. Slip the rope over the hook on the wall to hang the frame.
