These solid teak wood planters are the highest quality and will withstand the elements. The high natural oil content of teak makes it both water and weather-resistant, as well as resistant to bugs and bacteria. It's ideal for use with planters because wind, rain, snow, termites won't damage them. Made with the best waterproof glue and stainless steel hardware. They do not need liners. All sizes have drainage holes (except the 13 x 3 x 3 herb planter) and are made to have the soil placed directly inside. All planters are raised off the ground with small feet = cleats. This allows the planters to dry out underneath. We have smaller sizes for herbs medium for flowers and large for trees.
