You’ll need these materials:
- 3/4 MDF Board/Wood Planks
- Sand Paper
And these tools:
- Tenon Saw
First, you need to cut 4 pieces of ¾ board that is 3 ½ x 43 inches as the base tier.
Then create corner slip joints. Take note that the slip joints should have a depth of 1 ¼ inches, but the slip joints for the BASE tier should be 1 ¾ inches deep. This is to ensure stability for the entire planter.
Measure 2 inches from the edge of each plank. Of course, the thickness of these slots should be ¾ where your planks can fit.
For the slots for the above tier, measure 8 inches from the inside edge of the first slot. See picture.
Remember that you should always measure inwards, so that your dimensions are even – two inches from the edge of the plank for the bottom slot, and 8 inches from the inside edge of that bottom slot for the slip joint of the above tier. This is the only measurement you have to remember throughout the construction.
Each tier has a distance of 8 inches from the inside edge of the previous tier, and the slots are cut 2″ from the end of each plank.
Use chisel to refine the slots. Sand the planks to avoid splinters. Apply at least two coats of wood preservative.
Assemble it in its final place…
… and you are ready to fill it with compost and plants!
