Large land areas in the world are too dry for trees to survive. Although water may be present in the ground, it is often too deep for small trees to develop a root structure to reach. The Groasing Technology employs

The water-filled reservoir releases small amounts (around 50 ml per day) of water into the ground by a wick to water the tree and to encourage the tree to develop a root structure. The box acts as a shield for the water in the upper ground, and this water then spreads down and out instead of being drawn to the surface and evaporated. Both

In dry areas, the soil around the plants is inoculated with mycorrhizae to release nutrients in the soil that would otherwise be chemically inaccessible to the growing plants. A wick is inserted in the bottom of the Groasis which is then lowered over the plants and filled with water. Two lids are put on, funnels inserted and a cap plugs the top lid.A'Hearn, Peter Groasis Waterbox tree planting demo (Video) '' TeacherTube'', 20 September 2010. Accessed: 5 December 2010.
