How To Build A Raised Garden Bed

How I built my raised beds with wood and corrugated metal.
These beds were built with 4x4 posts, 2x4 crossbeams, corrugated metal roofing panels and some decks boards for the top. Filled with a 50/50 mix of topsoil and composted manure, then topped off with mulch after planting. Trellis is made of t-stakes, cattle panels (8 ft and 16 ft long, both 4 ft wide) and some zip ties.
