When building or buying a wood window box, your choice of wood can make a big difference! Some woods, like cedar and redwood, are much more durable and rot-resistant.

The natural beauty of wood makes it an optimal material for a window box. Whether you’re building your own wooden window box or selecting the best one to buy, careful thought should go into the wood you choose.

First, be mindful that not all wood is created equal. Some types are especially durable while others are prone to degradation and rot. Pine, for example, rots relatively quickly. That’s not what you want from a window box, which will be in regular contact with moist soil and suffer rain and snow. Because of their rot-resistant qualities, cedar and redwood are two of the best choices of wood for window boxes.
