Delivers the perfect amount of water to your plants!

The Leonard ArborRain Hydration System provides total water coverage for your plants and trees. This high-capacity model holds 20 gallons of water. It utilizes two removable emitters to release this water slowly over a 5 to 8-hour period. The 1-5/8-inch diameter fill port features a threaded cap and fits a wide variety of hoses for quick filling. This model fits trees and shrubs up to 6 inches in diameter. The durable plastic material contains a cold weather additive and a UV stabilizer to protect it during prolonged sun exposure.

The Leonard ArborRain Hydration System makes the water seep deep into the soil. It provides total coverage by hydrating both the root ball and the surrounding soil. This coverage is crucial for newly-planted shrubs and trees as it reduces transplant shock. You can also install multiple ArborRain systems around the drip line of established trees. The helps them thrive in hot and dry conditions.

We design the Leonard ArborRain Hydration System with a low profile. This low profile, along with its brown color, help it blend into your landscaping. Additives allow for long life outside in the sun and provide resistance to cold weather. We cover this product with a 5-year warranty!

Great watering system wrote

Easy to use and great for smaller trees or shrubs. Very well made and provides nice slow release . To top it off, A.M. Leonard are great folks to do business with.

I really like these water bags, they lay on the ground and don't pull on the trees like other tree bags that stand up. 20 gallons of water every other day in the summer heat and my trees look great. I have 13 of these and plan on purchasing another 7.

quality product - worked as expected. Each unit included two discs that looked like they remnant from the die cut for the fill cap. Would be great if that could be left partially attached to help keep mulch/dirt out of the filler area. I used one to cover while I mulched, but don't expect it to remain in place.

Saved our fruit trees wrote

Perfect product for remote watering of our apple trees. With the mild drought we've experienced I was worried we would loose the young trees. These bags do the trick of slowly watering with soaking deep into the soil.

Excellent product for watering newly planted trees. Very durable and easily filled with large filling with large screw on port. Oklahoma has some very hot and dry summers. These are great.
