Build a Landscape Timber Raised Bed

No fine carpentry needed—just some heavy lifting and a couple of weekends.

Choose durable timbers: pressure-treated 5x6, 6x6, or 6x8 in 8-foot lengths. You’ll need a 3/8-inch extension bit for drilling. A chainsaw eases cutting but follow all safety precautions; wear gloves and eye protection when cutting treated lumber.

Instructions

1. Dig a trench. Where timbers rest, dig a level trench 2 inches wider than timbers and 3 inches deep.

2. Create a foundation. Pour and level a gravel base nearly flush with surrounding grade.

3. Begin courses. Lay first course on gravel. Bore 3/8-inch holes every 3 feet. Insert 2-foot pieces of 3/8-inch rebar into holes and pound flush.

4. Top it off. Attach final two courses with 12-inch spikes, predrilling 3 inches with a 1/4-inch bit.
