Having outdoor gardens or plants can be an enjoyable hobby for anyone. If you live in colder climates you will want your cold-sensitive plants to be in mobile planters that can be moved into and out of the home as the seasons change. And in any climate planters make it easy to move plants from spot to spot outside. Basic planters can be constructed out of wood using five boards and a minimal set of tools.
Attach one side board to the base. Begin by setting one of the three long boards on the work surface with one of its long edges facing up. This board will be the base of the planter. Apply a bead of wood glue along the length of the long edge.
Lay the base down with the unglued long edge against a wall or other flat object. Place a second long board against the glued edge of the base so that one face is pressed against the glue. This is the first side board. Drill four screws spaced equally along the face of the side board into the edge of the base. Let the glue dry.
Attach the other side board by repeating steps 1 and 2--apply glue to the other edge of the base and attach the other side board with four screws. You now have the base, front and back of the wooden planter assembled.
Attach one of the short boards to one end of the assembly. Apply a bead of glue along the end edges of the base and sides. Press one face of the end board against the glued end of the assembly. Drill two screws through the end board into each side and the base of the assembly. Let the glue dry.
Attach the other end board by repeating step 3. You now have all four sides and the base of the wooden planter assembled.
Turn the wooden planter over so the bottom is facing up. Drill ten drainage holes through the bottom of the planter. Space the holes out along the length of the bottom.
Sand down the edges and any rough spots along the sides. Make sure the screw heads are flush with the wood. Apply weather sealant or outdoor stain to all sides of the wooden planter with the paintbrush. Allow the planter to dry completely before using.
