The most difficult area will be in designing your garden bed layout. Keep in mind the idea that the 8' long ties make good, average sized beds without cutting. 4'x8' needs only one cutting per tie. Try to allow at least 24"-36" walkways between beds. This allows ample room for children to walk or sit while working in the garden. When you have designed your layout you are ready to begin cuting the ties and placing them in their desired locations. Do not put the rebars in place until the entire garden is laid out. (This will save a lot of work if extra cuts are needed. When ready, drill holes through the ties, placing one rebar about every 8'. Butt ends together and place an 8" rebar into holes drilled into the center of both ends. These 2 placings of rebars will hold the frame in shape as well as tie them down to avoid shifting. 18" rebars are needed for the 8' placements. When beds are secure, fill with top soil to about 2/3 full. Plant plants and top with mulch to control weeds.
