How to Make a Garden Trough

When first unmolded, the trough can be textured. By going over the surface with a coarse wire brush and knocking down any sharp corners, you can add hundreds of years of "weathering" and impart an aged look. Once you've distressed the trough, wrap it in plastic and leave it in a cool place to cure for about four weeks, when it will have reached maximum strength. Then it's ready for planting.
