Back-Saving Raised Garden Beds
He recently sent FARM SHOW photos of 2 raised gardens he built that are 30 in. tall – much taller than conventional 6 to 12-in. tall raised gardens.
Each bed measures 16 ft. long by 4 ft. wide and 30 in. tall. The bottom is lined with galvanized chicken wire to keep moles out. The bed is filled with topsoil enriched with compost. Cross braces inside the bed are covered with scrap sheet metal to minimize soil contact with the treated lumber.
After building the wooden frame, Gallaher boxed it in with sheets of blemished metal roofing that he got from a local supplier. Only the white back side of the metal is visible.
Vertical wooden posts on each side of the bed support a shade cover made from a 16-ft. wire cattle panel that’s topped with plastic lattice. It provides about 60 percent shade. The lattice attaches to the cattle panel with nylon wire ties.
The cover is held in place by a pair of 8-in. long spikes that fit into slightly oversized holes drilled into the posts in 8-in. increments. One hole is spaced 1 in. above the other, so that one of the spikes fits below the cover and the other fits above it. “To raise or lower the cover, I simply change the position of the spikes. The spikes on top of the covers prevent wind uplift,” says Gallaher.
Another cattle panel arched between the 2 beds forms a trellis for cucumbers and other climbing plants.
The only non-treated lumber used was the 2 by 6 top lip that will be in contact with the gardener during use. This board will be easily replaced when it eventually rots away.
“I’m really happy with how it turned out,” says Gallaher. “The shade provided by the lattice allows my lettuce to keep growing even in the hottest part of the summer. In dry weather I put a soaker hose on top of the lattice to form a cool, soft rain for the plants.”
