To make a hypertufa pot, first put on rubber gloves and a dust mask for safety. Then, combine Portland cement, perlite or vermiculite, and peat moss in equal proportions in a large container. You can also make the mixture with two parts cement, three parts peat moss and three parts perlite. Sift the ingredients together until they are well mixed, and then slowly add water until the mixture has the consistency of cottage cheese.Continue Reading
To test for proper consistency, take a handful of the mixture and squeeze it. The mixture should clump together, and a small amount of water should drip from the it. Leave the mixture to rest for five to 10 minutes.
As the mixture rests, prepare a 5-quart pail or plastic container by spraying the inside with a nonstick cooking spray. Press the rested mixture against the inside of the pail, coating the bottom and sides. Spray the outside of a 2.5-quart pail, and place it inside the larger pail.
Gently tap along the outside of the pail to force any pockets of air to the surface. Smooth off the top of the mixture. Seal the pot in a plastic bag, and allow it to cure for 24 to 36 hours. Remove the pot from the plastic bag, and set it somewhere to dry for another two to three weeks. When the pot has completely dried, use a rubber mallet to gently tap the pot out of the pail.
Use sandpaper to smooth any rough edges and a drill to create drainage holes.Learn more about Outdoor Plants & Flowers
