A strawberry pyramid improves soil drainage, while giving room to grow more strawberries in a smaller space. To build your own, choose long-lasting wood such as cedar or cypress, or use cheaper pine or scrap lumber and plan to replace the tower in a few years if the wood rots. Avoid treated lumber, since the chemicals used for treatment may leach into the soil. Adjust the size of the pyramid to fit the space that you have available, leaving room on all sides to pick the strawberries.
- Skill level:
Things you need
- 4 boards, 1-by-4-inch-by-8-feet
- 1 board, 1-by-4-inch-by-3-feet
- Measuring tape
- 2 1/2-inch-by-1/4-inch screws
Measure a 1-by-4-inch-by-8-foot board with a tape measure and draw lines across it using a square, so you can cut it into the following lengths: 30 inches, 27 inches, 21 inches and 15 inches. Saw the board to those lengths with a hand saw or circular saw. Repeat with three other boards, so you have four pieces of each length.
Saw a 1-by-4-inch-by-3-foot board into four pieces, each 9 inches long.
Drill three 1/4-inch-diameter pilot holes in one of the 30-inch boards, 3/8 inch from the end. Hold a second 30-inch board against it at right angles and drill 1/8-inch pilot holes through the first holes, into the end of the second board. Screw the boards together, using 2-1/2-inch screws. Drill similar holes in the second board and screw a third board to it at right angles to create a U-shape with three boards. Attach the fourth 30-inch board the same way, across the end of the U, to form a square.
Drill three 1/4-inch-diameter pilot holes in one of the 27-inch boards, 3 1/2 inches from the end. Hold a second 27-inch board against it at right angles and drill 1/8-inch pilot holes through the first holes, into the end of the second board. Screw the boards together, using 2-1/2-inch screws. Drill similar holes in the second board and screw a third board to it at right angles to create a U-shape with three boards. Attach the fourth 27-inch board the same way, across the end of the U, to form a square. Unlike the first square, this square will have boards sticking out about 3 inches from each corner.
Repeat the same steps with the 21-inch boards, attaching the boards 3 inches in from the ends to create a smaller square with boards sticking out at each corner.
Repeat the same steps with the 15-inch and 9-inch boards.
Set the largest square where you want your strawberry pyramid to be and fill it with soil.
Set the next largest square on top so the boards sticking out on the ends rest on the square below. Fill it with soil.
Stack the rest of the squares on top from largest to smallest, filling each with topsoil.
Tips and warnings
- When strawberry growing season is over, if you want to use the space or move the planter before next year, disassemble it and store the squares nested inside each other.
