Prime Source Tree Mate is a slow-release watering bag that's specially designed to help water your trees and shrubs properly over a six to eight hour period. A single bag holds 20 gallons of water and can fit trees up to 4" caliper. TreeMate Select ensures that your newly planted trees will endure their first year by delivering water directly to the root system using a drip irrigation system. It is made of heavy-duty coated, woven green polyethylene with poly straps, nylon webbing, and black nylon zippers. It is safe to use with any chemical additives or nutrient. This bag increases efficiency and water conservation as well as guarantees to produce a beautiful and healthy tree.

The bag prevents evaporation and water run-off and delivers excellent saturation. It decreases the prospect of damage by frost during the Fall and Spring, when fresh trees are likely to be planted since its continuous supply of moisture repels the damage of changing temperatures. The bag is good for soaking before the digging, delivering a constant water supply during those periods of droughts, and decreases the risk of shock of transplanting.
