Vertical wire is another great option for a garden trellis. Attach sticks on either end to stake into the ground and put on the edge of whichever plants need a little help. If you have a privacy fence in your backyard, this idea will spruce up the space where your garden is. (via Dreaming Gardens)
Copper tape repels slugs and creates a finished, tailored look. The tape "comes in different widths to accommodate the size wood you choose to build the raised beds," says Luna. If you use 6-inch-wide copper tale, it will give you a 2-inch lip on each side of a 2-inch top edge. A 13-foot-long roll of Copper Slug Tape (1.25 inches wide) is $9.95 from Gardeners Supply.
