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.

Pallet Planters
This blog post shows several ways of building planters with free wood shipping pallets. Be sure to use pallets stamped as non-toxic. This stamp denotes that the pallets have not been treated with pesticides. Our Natural Building Blog now has about a dozen pages of free information on almost every aspect of pallet building (floors, paneling, walls, furniture, etc.). Use the search engine on the right side of the page using ‘pallet’ as the search phrase.
