What Houzzers are commenting on:
Decking and planters: Only certain species of wood hold up well as a decking material. Use those with a natural resistance to the elements. Pressure-treated decking is a soft wood that has been treated with chemicals to make it weather resistant. The arsenic that was used in the past is no longer used, but if you are looking for a chemical-free deck surface, avoid pressure-treated decking. There are alternatives, but the structure of most decks will be built with pressure-treated timber.
