Wooden planter boxes can add a note of nature to a deck or patio. They can add much-needed planting space, perfect for flowers, perennials or even for establishing a small vegetable garden. With simple tools and materials, you can build planter boxes that are ideal for a deck or patio.
With a circular saw, cut a piece of 2.5 by 25 cm (1 by 10 inch) pressure-treated timber 90 cm (3 feet) long; this will be the base of the box. Drill a series of 9 mm (3/8 inch) holes in the board to allow excess water to drain out.
Cut two pieces of 2.5 by 10 cm (1 by 4 inch) timber 25 cm (10 inches) long, and nail these to the bottom of the base to make 60 cm (2 feet) for the box. This will allow water in the box to drain out without pooling under the wood of the base.
Cut two pieces of 2.5 by 25 cm (1 by 10 inch) timber 95 cm (38 inches) long. Nail these to the base so they extend vertically along the long side of the base. Make sure that there is an equal 2.5 cm (1 inch) overhang on each end of the base.
Cut two pieces of 2.5 by 25 cm (1 by 10 inch) lumber, each 25 cm (10 inches) long. Nail these to the ends of the base, so that they extend vertically and complete the form of the box. Nail the end and side pieces together where they overlap.
Paint or stain your planter, if you desire.
You can increase or decrease the size of your planters to match your needs.
