How to Make a Planter Box for a Garden


Planter boxes allow you to fill planting space with quality potting soil while avoiding typical gardening issues such poor soil, lack of sufficient space, back problems or rodents. Add wooden blocks at each corner of the planter to form 'legs' for the box, thus lifting it off the ground to prevent you from bending low while gardening. Place it in your garden, balcony, patio, or even inside if you lack gardening space, and enjoy container gardening with flowers, vegetables, herbs or fruit.

Step 1

Cut your wood into the desired dimensions for your planter box. Measure the spot where you will display the planter to determine the height, width and length. Keep it 8 to 9 inches high, and up to 3-feet wide. Use a handsaw to cut wood into five boards: a base, two short sides and two long sides. Sand the edges to prevent cuts.

Step 2

Hold one of the long sides (the front of the planter) flush against a short side so they form an L-shape. Butt the corners so the top and bottom of both pieces are level. Drill screws to join them together.

Step 3

Place the other long side (the back of the planter) flush against the second short side to form your second L-shape. Align the top and bottom of both to ensure they are even before drilling both boards together with wood screws.

Step 4

Dry fit both the L-shaped structures so the short side of one structure touches the long side of another to form a rectangular box. Butt the corners so they are level before drilling three screws at each end to join the structures together.

Step 5

Drill ½- to ¾-inch drainage holes, spaced randomly apart, over your base. Rub sandpaper over the holes.

Step 6

Turn the planter over so its base-side faces upwards. Lower the base piece over the cavity, and adjust it so it rests evenly on all four edges. Drill four to five screws to attach it to each long side, and three screws per short side. Drill wooden blocks, if any, at each corner so they lift the planter up to give it added height.
