You've heard many experts say that light and frequent irrigation is the most effective way to establish trees and woody ornamentals - the TreeBuddy is the first truly portable drip irrigation system that makes light and frequent watering possible, and it makes irrigating the "right way" cheaper and more convenient than the "old way."
The 25-gallon TreeBuddy by far is one of our most popular products with professional contractors. It holds a lot of water - over 25 gallons. It will keep a 3-inch caliper tree irrigated for 3 weeks between refills! It fits on any type of tree, multi-stems, conifers, you name it! Its setup time is quick and easy and comes complete with everything you need except water. It places absolutely no lateral force against the trunk of the tree, plus it allows air circulation which prevents mildew formation and stem discoloration.
There are many advantages of using TreeBuddy. The TreeBuddy only requires refilling every 10 days. Large trees do not require multiple TreeBuddy's. Because of its low profile, the TreeBuddy allows air circulation around significantly more of the tree's trunk.
