How to Build Redwood Planters


Line your driveway, porch or entrance with planters made from redwood. Fill the planters with soil and add bright annuals, perennials or biennials that add a warm and welcoming touch to the area. Planters made from a variety of material are available commercially, but making them yourself allows you to customize each to fit your needs and the available space. Redwood is naturally disease-resistant and can add a tinge of grandeur to a spot.

Step 1

Measure the spot you want to decorate with the planter to determine size. Notice how the planter filled with plants or flowers will look on that spot and determine its height, length and width. Note the measurements.

Step 2

Cut the 2-by-6 redwood boards down to size with a miter saw. These boards will frame the four sides of the planter. Use as many boards for each side that achieve the desired planter height. Refer to the noted dimensions on the paper.

Step 3

Lay boards for each side on a table. Join parallel boards that form a side of the planter with each other. Hammer a corrugated metal fastener to join a board to the one next to it. Use three fasteners to join boards longer than 15 inches.

Step 4

Measure the width of each side and cut four lengths of 2-by-2 redwood 3 inches shorter. Use a miter saw. A redwood board that measures 2-by-6 is actually 1-1/2 inches thick and 5-1/2 inches wide. Determine the required length of each 2-by-2 by multiplying the number of boards per side by 5-1/2 and subtracting 3 inches from the result. So for three boards per side, the resulting figure is 13.5, and for seven boards it is 35.5. Cut two lengths of 2-by-2 redwood at 13-1/2 inches and another two at 35-1/2 inches.

Step 5

Secure the 2-by-2 boards to each side of the planter with drywall screws. Make sure the end of each board falls 1-1/2 inches short from the edge of every side. Cap the edges of the long sides with the short sides using drywall screws.

Step 6

Measure and cut plywood sheet for the base of the planter. Keep it 35-1/2 inches long and 13-1/2 inches wide. Drill 3/4-inch drainage holes over the surface, spaced 4 inches apart. Flip the planter over and secure the base in place with drywall screws.
