A pyramid planter makes use of vertical space, allowing gardeners to grow different types of flowers, herbs or plants in one area. The planter improves drainage, reduces chances of weeds, insects or pests and increases the yield because every inch is exclusively meant for planting. Built from good-quality, untreated lumber, the pyramid planter towers upward, while providing plenty of space along the sides to grow your favourite upright or trailing plants, flowers or even strawberries.
Things you need
4 8-foot long, 1-by-4-inch boards
1 3-foot long, 1-by-4-inch board
Drill and drill bits
2 ½-inch-by-1/4-inch galvanised screws
Measure and mark an 8-foot long, 1-by-4-inch board into four pieces: 30 inches, 21 inches, 27 inches and 15 inches. Cut over the marks with a circular saw or handsaw. Repeat the procedure with the other three identical 8-foot lengths so you have four boards of each length.
Cut the 3-foot long, 1-by-3-inch board into four 9-inch long pieces.
Place one of the 30-inch boards on an even surface and drill three ¼-inch wide holes, 3/8 inches from one end. Position a second 30-inch board at a right angle to the first one. Drill 1/8-inch pilot holes through the holes in the first board that penetrate the second board. Insert 2 ½-inch galvanised screws through the holes to secure the boards together.
Drill identical pilot holes through the end of the second board and secure the third 30-inch board to it at a right angle, forming a U-shaped structure. Secure the fourth identical length to the end of the structure to form a square.
Drill three ¼-inch wide pilot holes through one of the 27-inch boards, 3 ½ inches from the end. Position the second identical board at its end, forming a right angle. Drill 1/8-inch holes through the first holes that penetrate the end of the second board. Secure both the boards together with 2 ½-inch galvanised screws.
Create a U-shape by placing an identical board at the end of the second length and securing it with screws. Secure the fourth length across the ends of the U-shape to form a box. Unlike the previous structure, the boards of this U-shaped structure will stick out 3 inches from each corner.
Repeat the process to form a square-shaped structure with the four 21-inch boards. Attach each length 3 inches inward from the edge to create a smaller square with boards sticking out from each corner. Also form two more squares with the four 15-inch lengths and four 9-inch lengths.
Place the largest square on the selected spot where you want to display the planter, and fill it with good quality potting soil.
Lower the second-largest square directly over the largest one, so the corner boards that stick out rest on the boards below. Fill it with soil. Stack each square directly on top of the previous one, filling it with topsoil, until your pyramid planter is complete.
