An elevated planter box for gardens.
4 – 2×6 @ 16 feet long (untreated lumber for health of vegetation; I used pine) $9.30 each=$37.20
1 – 4×4 @ 8 feet long (I used treated cedar to last longer) $6.97 each
40 – 2″ wood screws (I used 14#) $5.58 box/25 x2=$11.16
24 metal strapties (16 straight to attach the box walls together; 8 bent to a 90-degree angle to use as support to attach legs to box base) $0.88 each=$21.12
Screws or finish nails to attach the strapties
Wood glue $5.47
Total Cost = $81.92 (as of 2/12/2011)
10 – 2×6 @ 60″ (box base & wall sides)
6 – 2×6 @ 19″ (box end walls)
4 – 4×4 @ 24″ (legs)
Drill two holes for screws on one end of A (2×6 @ 60”). We spaced ours at ¾” from the end and 1 ½” from the sides. Set one B (2×6 @ 19”) at a 90-degree angle lining up the ends of A & B; screw one 2” wood screw into each hole, forming an L-shape. Repeat on C & D, E & F, G & H, I & J, and K & L, so that each side has and piece on it.
On one of the boxes, line up four 2×6 @ 60” (box base, M, N, O & P) pieces side by side. Drill two holes in each piece from the bottom piece into the box end piece. Repeat for all four boards so that one of the three boxes has a solid base.
Flip the box over so the base is facing the ground. Wedge each leg (Q, R, S & T) under the base or prop one side up so you can attach one leg or lay the box on a side; use a helper! Line up one 4×4 @ 24” on the end and side of the base and drill a hole through the base into the leg and use one wood screw to attach the leg to the base. Use two bent strapties, one on each side of the leg that touches the base, and additional screws and/or nails to attach the straptie. Repeat for each leg, for a total of 8 strapties. Flip unit over so that it is standing on its legs. You should now have a base box on legs.
You will now attach the two remaining box walls to the base. Apply a layer of wood glue to the top of the box wall on the base unit. Using 8 straight strapties on each box wall, attach one straptie from the base box wall to the loose box wall with screws and/or nails on each end, near each corner. Repeat for
We’re leaving the box untreated so as not to harm any vegetation that will be growing in it. You can use treated lumber on the legs for durability. I also add the disclaimer that I am NOT a woodworker or designer so use at your own risk!
Last year, our garden was all in-ground and was infested by stink bugs and vine borer beetles! this year, we're trying these elevated planter boxes!
