Attaching landscaping timbers requires the use of iron rebar spikes and a sledgehammer; some level of physical fitness is necessary to successfully complete the process. A level of caution needs to be adopted in attaching landscaping timbers, as working with a sledgehammer can be dangerous.
Properly connecting landscaping timbers helps to ensure that the timbers do not shift out of their original position and they will last much longer once they have been attached.
Drill a hole in each end of the landscaping timbers and one in the center. Drill a hole every 3 to 4 feet along the timbers if you are creating a border or edging for your lawn.
Use a drill bit that is narrower than the rebar stakes you will be using to attach the landscape timbers. A 3/8 inch bit will work in most cases. Alter the dimensions to fit your needs.
Place a rebar stake in one hole once all holes have been drilled. Begin at one end of the landscaping timbers and hammer in one stake at a time as you go.
Push the rebar stake as far into the hole as you can while keeping it vertical.
Use the sledgehammer to pound the rebar stake through both landscaping timbers and into the ground for added hold.
Check each stake to be sure that the end is flush with the wood or even slightly below it for safety.
