Our planters are made from high quality fir wood, 100% natural material. 6.5 "depth is enough to hold 66lbs of soil to grow fruits, flowers, or vegetables. The Planter trellis can be hung with plants up to 11lbs and can accommodate some vines. Nails are inserted into every joint to keep the trellis from becoming deformed. The water drainage hole at the bottom of the Planter bed give the plants a better environment to grow and prevent root rot. The lock wheel at the bottom allows the planter to move more easily and can be placed outdoors in sunny days or indoors in bad weather. If you are a gardening enthusiast, you must not miss this planter.
