Joel M. Lerner - CEO, Environmental Design
"Treegator® is a brilliant invention. Not one drop of water is lost to runoff or evaporation. This is the most water-efficient system I have seen."

Amazon Customer
"We have 4 of these (Treegator® bags) and not one tree has died since we began using them. I think we should plant some more trees just so we can have pleasure of watching these guys in action!"

Travis Mohrman - City of Ballwin, MO Parks & Rec
"I have used (Treegator®) bags for years. For a city, they are perfect, because they effectively and efficiently water our trees while not costing us many man hours at all."

Amazon Customer
"Our little 5-foot tree had only sprouted maybe 10 new leaves after we planted it, and it's existing leaves were small and kinda stuck at a certain size. Once we put (a Treegator®) on, it grew brand new branches that are now about 3 to 4 feet each, with large, healthy leaves all along them."

Alvaro DaSilva, - ADS Landscapes, Inc.
"I am really surprised to see how easily Treegator® is to install. They really got the job done effectively and concentrated the watering to the intended area; leaving the job site still dry and maneuverable."

Amazon Customer
"We lost a newly planted tree a couple of years ago because we just struggled to keep it watered well through a hot summer. Last fall we planted a new one, about 7 feet tall, and bought (a Treegator®) for watering. It's so easy to fill within a couple of minutes and walk away. Well worth every penny!"

Double Bag Setup
Use a Treegator® Original Slow-Release Watering Bag on small as well as large trees.
Water trees up to 8 inches in trunk diameter by zipping two Treegator® Original bags together back-to-back.
When two Treegator® Original Bags are zipped together back-to-back, it allows each bag to expand more than it normally would when zipped to itself around the trunk of a tree as a Single Bag setup.
The amount of water each Treegator® Original Bag can hold when used in a Double Bag Setup can be up to 25 gallons, but actual water capacity is dependent upon the trunk diameter of the tree being irrigated.


Once a Week Watering
Compared to conventional watering methods, Treegator® Slow-Release Watering Bags can reduce your watering frequency to just one refill every 5 to 7 days

Lifetime Limited Warranty
Every Treegator® Original is backed by a lifetime limited manufacturer warranty against any defects in materials and/or workmanship.
