Hypertufa Recipes

Hypertufa recipe

There are many different recipes for hypertufa on the internet.

Each individual works with a recipe that turns out for his or her own needs. The recipes are nearly the same but , as one person wants a "light" recipe and another wants a "heavy" one, you need to experiment to find what suits you. And I mean that heavy/light in both weight and in winter survival.

Here in Ohio, zone 5, I need my hypertufa planters to be frost hardy. I want it to survive winter after winter, without cracking, whether it goes to zero or 20 below. ( Not to mention my precious plants inside the planter!)

It needs to be mentioned that a wet/frozen planter is not going to survive as well as a dry/frozen planter. So don't situate your planter under an overhang where it will be drenched in each winter rain. Move it !  And put it upon a pedestal of bricks or rings so that it is not left sitting on the wet ground..... or horror! ...in a puddle.

  • My best recipe:  

            1 part portland cement

            1.5 part peat moss

            1.5 part perlite or vermiculite

 

  • Another recipe:

            1 part portland cement

            1 part peat moss

            1 part perlite or sand ( or half and half each)

 

Water

The final ingredient is water and that is subject to your humidity etc. Add it slowly such as half gallon of water ( when you are using a gallon container as your part), then keep stirring and mixing,  and adding a little at a time while you observe your mixture.

You can use a short handled garden hoe, or a trowel, or your gloved hands.

You will be mushing this around like making a meat loaf or brownies etc.

If you have any problem getting these supplies, here is a source.

I use a gallon plastic pitcher as my measuring unit most of the time. So using the ratio , I fill it once for the portland cement,  one and a half times for the peat , then again for the perlite. 

It is the ratio you use for any measuring unit:  1 to 1½ to 1½.

Portland cement to perlite to peat moss

 If you are using a pint container, then fill it once for Portland cement, and one and a half times each for both the peat and the perlite.

So using this gallon as my "part",  if I were doubling the above recipe, then use 2 containers Portland, and 3 containers of both the peat and perlite.

You're getting the same ratio either way.

Once it is mixed, leave it to set and absorb for a short time, such as five minutes.

When you come back after 5 minutes, mix again and add a little water if you think it needs it.

Rule of thumb is  when you pick up a handful and squeeze, only a few drops should squeeze out between your fingers. But you do need to see those

drops. Too dry and you will have a hard time molding it.
