I got four of these Versdek planters for tall birch trees. Of all the planters Ive purchased these are definitely the best value. Large planters are expensive and these look FAR above their purchase price. They’ve held up incredibly well through NYC seasons (photo taken June 2020 of planter purchased Spring 2019). Definitely heavy when full! There is about an inch of rigid styrofoam on all sides (movable and removable) which is for insulation against colder temperatures.
