DIY Hypertufa Trough Containers: Recipe & Molding Guide

Hypertufa troughs are lightweight, stone-look planters you can craft at home with just three ingredients. Here’s the simple recipe and step-by-step molding method.

Hypertufa Mix Recipe

• 1 part Portland cement
• 1 part sand
• 2 parts peat moss (or substitute perlite or sphagnum moss for a different texture)

Mix dry ingredients thoroughly, then slowly add water until the consistency resembles thick oatmeal.

Molding a Small Trough (Using Plastic Pots)

1. Cut a 3-gallon plastic pot down to 8 inches tall.
2. Line the inside with a plastic bag (a garbage bag works well).
3. Place a 1-inch layer of mix in the bottom.
4. Set a 1-gallon pot centered on that base.
5. Pack mix firmly between the two pots with a stick.
6. Cover the whole mold with another plastic bag and let cure for 2 days.
7. Carefully remove the trough; let it harden for 2 more weeks. During this time, roughen the sides with a dull knife or old fork for a natural stone appearance.

Larger Troughs (Cardboard Box Method)

Use two nested cardboard boxes of different sizes following the same layering and packing process. The cardboard will peel away after curing.

Hypertufa troughs are perfect for alpine plants, succulents, or a miniature “Vidalia Onion Garden” entry at the Southeastern Flower Show. Experiment with shapes and enjoy your custom stone-like containers!
