Winter Project - Making Hypertufa Planters
After leaving the hypertufa for 24 - 48 hours to set, the planters were ready to be unmolded. (Using cooking spray helps.) Now they'll be covered in plastic and left to cure for at least a month. The curing process helps to strengthen the hypertufa - allowing you to leave it outdoors during the winter while other materials may split or crack. Once cured and completely dried, the hypertufa should lighten in color.
I can't wait to plant these up with all sorts of alpines and succulents this upcoming summer. Traditional rock garden plants will thrive in these shallow planters. If you're interested in learning more about how to make hypertufa, here are a couple of great instructional videos.
