I’ve seen garden towers gaining in popularity over the last two years or so but didn’t pay a whole lot of attention to them because of concern about chemicals leaching from the plastic. Richard, a long time reader, explained how a whole garden of closely spaced towers would produce a huge quantity of food in a small area such as a backyard garden where space is often limited. Instead of using plastic, the planters could be made out of safer materials such as terracotta, ferrocement or metal at far lower cost.
