Thermally modified hardwood Planters/Raised Garden Beds for vegetables and flowers are easy to assemble without any tools or fasteners. These planters look like a fine piece of outdoor furniture， rather than rough pine construction boards forgotten by builders in your yard. The construction consists of two types of parts: Sideboards with dovetail tongue and Corner Posts with dovetail grooves， which can be combined to create multiple configurations as all parts are compatible. We offer 5 standard sizes planters: 2'x2'， 2'x4'， 4'x4'， 2'x8' and 4'x8' in two heights: 6" and 12". In addition， we offer three configurations of cachepots for interior and exterior use. The benefit of thermo-treatment of wood is that the process leaves the wood naturally protected against decay on a molecular level while beautifying the wood by giving it that deep exotic look. It is a 100 percent green product. Also， our planters don't need liners to protect plants from harmful chemicals. The latest research also shows a beneficial influence of thermally-modified wood on plants and vegetables. In addition， thermally-modified wood has a natural resistance to termites， insects， and bacteria， adding additional protection for your plants.
