Here’s the right place to get instructions for making some unique garden art, and recipes to try.

Not all recipes will work for every project, as many are better for smaller containers and pots. Extremely strong mixes of hypertufa are necessary for hypertufa birdbaths and other large garden art projects such as hypertufa troughs.

Basic Rules for How to Make Hypertufa:

Please see the section on Hypertufa How To - Safety before you start.

Recipes for hypertufa are limitless, but some work better than others.

Keep in mind too that not all cement powder, peat moss or sand is created equal, and regional differences mean that even if you follow the recipe exactly you may experience some unique challenges.

Use this recipe as a guide, and test it on smaller projects first, such as pinch pots. Once you get an idea of how the materials perform, you can feel more confident about making bigger hypertufa projects such as larger containers, troughs and birdbaths among other unique rustic creations.

Mix one part by volume of each of the following: (this means use several yogurt containers, coffee cans or other measuring container so you can measure each part using the same sized container)

Cement powder – sometimes called Portland cement. Avoid using pre-mixed mortar as this contains sand which may impact the proportions.

Peat moss – sometimes called sphagnum peat moss. Sieve this through 5mm mesh to remove twigs and large clumps by sieving it through a screen with 5mm openings.

Sand – Builders sand is used by construction companies; don’t use beach sand as it may contain salt.

Add water to mix to a consistency of peanut butter (plastic and malleable).

Place it in your prepared mold, and form it into place. Avoid over doing it, as it will just crumble. Some recipes also contain perlite, fiberglass strands, vermiculite and other additional materials.

You can test these after you get the basic recipe to work.

Once you’re confident you know how to make hypertufa, the world is your oyster. I’ll bet you won’t be able to stop at just one hypertufa project for your garden.
