Making Hypertufa Troughs

With John Tsutakawa

Trough gardening has become popular in rock gardening. It’s a perfect container for growing small alpine and other plants.This talk will cover hypertufa trough making. John will explain how to use forms and molds, hypertufa recipes, using reinforcement, finishing, curing and planting.

John specializes in alpine container and rock gardening. He grows and propagates alpine plants, as well as Meconopsis (blue poppies). 

He has made troughs for over twenty years, using molds and wooden frames. Recently John designed and organized the Rock Garden at the Gardens at Lake Merritt. This garden includes 12 large troughs and a center crevice garden. ​
