Garden containers play many roles in a garden. They serve as boundaries separating one garden room from another, they allow a gardener to plant on decks and patios near to the house, they make great gifts and, as the editors of the Sunset "Woodworking Projects" point out, a large wood planter with a single shrub "can become a striking landscape element." This wood container will work for a large shrub, such as a rhododendron or witch hazel; a single small tree like a dwarf lemon; or for an assortment of colorful annuals or herbs.
Cut the sides, bottom and corner braces of redwood, pine or another softwood in the dimensions indicated in the "Things You'll Need" section. A table saw is convenient, but not required since you have only a limited number of cuts to make.
Rout or use a dado saw blade to create a ½-by-½-inch rectangular groove, approximately 4 inches from all sides, on each of the four 2-by-10-inch panels. This an optional step to add decorative interest to the planter box.
Drill five ¾-inch holes through the bottom piece for drainage.
Nail the four sides together with the ends of the sides abutting each other.
Nail the four corner posts to each corner for added support.
Attach the bottom to the sides by placing the sides upside down and nailing on the bottom piece.
Seal the joints of the box on all sides and the bottom to prevent seepage from the sides.
Paint or stain the box to the finish you desire. Leaving the wood unfinished is a common treatment for wood planters, but painting, stenciling a design or staining are possibilities as well.
