The DeWitt Dew Right Tree Bag is a twenty gallon tree watering bag that puts water where the tree needs it the most. The bag is placed around the base of a tree and filled with water. The bag then releases water over a period of five to eight hours, which allows a good soak. This prevents runoff and evaporation during hot, dry weather, and provides newly transplanted trees a much improved chance of becoming established. This is a sensible solution for parks and rec departments, for municipalities and golf courses, and for regular homeowners who are finding their trees stressed by the hot dry summers that seem to be the new norm. The bags are easy to install in just five minutes, and require no special tools. The bag ships at 30x30x5cm (12x12x2″).
