The tree T-PEE is a cone shaped, water and nutrient containment system designed for trees 1-5 years old, and made in the U.S. from 100% recycled plastics. They typically come in two colors: Black and White. The Black tree T-PEEs were designed for use with trees that flourish in heat and in tropical environments, such as citrus. The Black tree T-PEE absorbs the heat, increasing the temperature by 12 degrees around the base of the tree. The White tree T-PEEs are good for trees that deteriorate in hot, tropical environments. See our tree T-PEE University for more information and the benefits of the tree T-PEE.
