Plans to Build Large Planters

Cut the 4-by-4 inch cedar into four posts that are 24 inches each. Cut the 2-by-1 inch cedar into four 36-inch lengths and four 24-inch lengths. Cut the 4-by-1 inch cedar into 26 18-inch lengths and four 24-inch lengths.

Lay two of the posts down flat on your work surface. Straddle a 36-inch piece of the 2-by-1 inch cedar 3 inches from the top of the posts and 3 inches from the bottom of the posts for supports. Drill two countersunk pilot holes through each end of the supports into the post, then screw them together with deck screws. Repeat with the remaining posts and 36-inch cedar planks.

Stand the posts upright 24 inches apart, supports on the outside. Clamp the 24-inch pieces of 2-by-1 inch cedar horizontally across the posts, matching up with the line of the supports already in place. Screw in place as you did the other supports to create a rectangular box.

Insert the four pieces of 24-inch, 4-by-1 inch cedar across the bottom of the planter. The ends should rest on the inside edge of the 36-inch supports. Arrange them so they are evenly spaced; there will be around 1 inch or so between each one to facilitate drainage. Nail in place with galvanized nails, two per joint.

Evenly space eight of the 18-inch, 4-by-1 inch planks over one of the 36-inch sides of the planter. Secure them to the support planks with two galvanized nails through each end. Repeat on the other side with eight more planks, then on the two ends with five planks on each end.

Line the interior of the planter with landscape fabric, securing it with the staple gun. Trim off the excess with the scissors.
