ArborRain™ Hydration System

• 20 Gallon Low-Profile Ring
• Two Removable Emitters
• 5-8 Hour Drip Time
• UV & Cold-Weather Additives

ArborRain™ Hydration System is a low-profile, watering ring that gives new trees and shrubs a long, deep soak. This 20-gallon unit wraps around trunks up to 6 inches in diameter and releases water slowly over 5 to 8 hours through two emitters, helping hydrate both the root ball and the surrounding soil. The 1-5/8 inch fill port with a threaded cap makes filling fast with most hoses, and the brown color blends nicely into mulched beds. We recommend using it right after planting and through the first hot season, since consistent deep watering is the best way to reduce transplant stress.

Unlike upright tree bags, this design rests on the ground, so it won’t tug on the trunk as it drains and it’s easier to use around low branches. The emitters are removable, so you can clean out any grit or mulch if flow slows. The plastic is formulated with UV stabilizer and cold-weather additives for longer outdoor life, and it’s backed by a 5-year warranty for manufacturer defects under normal use.

Product Tips

• Set it on top of a level mulch layer and center it evenly around the trunk before filling.
• Add a few gallons first, then pull it into a smooth ring shape so the bottom sits flat, and finish filling.
• Don’t try to move it when it’s full; start with only a few gallons if you need to reposition it.
• If flow slows, remove and rinse the emitters to clear debris.
• For established trees in drought, place multiple units around the drip line to spread coverage.

FAQs

How is this different from a standing tree watering bag?

It lays flat on the ground and irrigates from the soil surface, so it doesn’t hang on the trunk or pull as it drains.

How long does it water after filling?

A full unit typically releases over 5 to 8 hours for deep, steady watering.

What size plants does it fit?

It’s sized for trees and shrubs up to 6 inches in trunk diameter (inside diameter).

Can the emitters clog?

They can if debris gets in while filling, but they’re removable so you can clean them out.

What warranty comes with it?

It’s covered by A.M. Leonard’s Down-to-Earth Guarantee and also includes a 5-year warranty against manufacturer defects under normal conditions.
