Add color to your indoor or outside space with homemade planters. Construct a simple square or rectangular wooden planter box and grow annuals, biennials, perennials or a mix for a varied and colorful blend. Use cedar, oak, teak, redwood, pine or other wood of your choice within your budget. Such container gardens are also suitable for apartment dwellers or office workers who lack garden space but want to take in the aroma and relax while watching vibrant flowers.
Measure and mark your desired dimensions on the wooden board, using a measuring tape and marker, and cut over the marks with a handsaw. Keep the planter up to 3 feet wide to access the vegetation planted in the center. Keep it 7 to 9 inches tall. Keep all sides of your planter equal if it is square, but keep two sides short (for the sides) and two sides long (for the front and back). Keep the base as long as the front piece, but its width should equal the sides.
Sand the edges of all the pieces to remove sharp edges or protrusions. Use a medium-grit sandpaper over the wooden boards.
Drill two equidistant rows of ¾-inch-wide holes over the base. Rub sandpaper over the holes on both sides of the base. These holes assist in drainage.
Place the base board on your work table. Hold the front board against its long edge. Butt the corners before drilling four wood screws along the edges to attach both the pieces together. Attach the back to the other long edge of the base the same way.
Place one of the planter's sides between the short edges of the front and back pieces. Align it so its top is in level with the tops of the front and back. Secure it in place with two wood screws on each side. Attach the second side piece to the corners of the back and front boards on the other side the same way.
Turn it over so the bottom of the planter faces upward. Lower the base piece over the cavity and butt the edges. Attach it with four wood screws on each long side and two on each short side.
Drill an additional wood screw for added stability if the joints aren't secure. Paint your wooden planter to protect it from natural elements, especially if placing outside.
