This TreeDiaper36 Advanced Hydration System mat is great for 3 inch caliper trees. Consider 2-3 years of growth prior to the tree's establishment. We recommend cover a circle area that is twice of the diameter of the rootball. If the rootball is larger than 18", consider larger sizes like TreeDiaper48.

 Simply soak the mat in water to get it started, then place it around your plants. Its user friendly circular shape consisting of two half rings is designed to be placed on top of various types of soil. If you prefer a natural look, just add mulch on top of the mat. Because the TreeDiaper® treemat is made from durable materials, it can be used for years!
