Make your own lightweight, stone-look planter with this simple DIY project. This hypertufa trough is perfect for container gardening and would be at home on any patio or porch.
Forms are often made from wood, but this 1-inch-thick foam insulation board is easy to find and you can cut it with a craft knife. Measure the size you want. Here, the pieces were cut to form a 16-inch square about 8 inches tall. Scoring the foam is an easy way to get a clean, straight edge. Simply run the craft knife along the edge of a ruler, then set the foam on the edge of a table and push down to break it.
