A smaller version of our popular ArborRain Hydration System!

The Leonard ArborRain Hydration System provides water to your valuable plants and trees. This 18-1/2-inch diameter model holds 2-1/2 gallons of water. This smaller profile design fits most 7-gallon and larger pots or grow bags. 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 slowly delivers water 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. This smaller version provides a 5-hour release and is perfect for tree saplings, perennials, vegetables, and container gardening.

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!

Please note that the ArborRain Quick-Fill Wand will not work with this product.

Great product wrote

I bought this product because I wanted to water 3 new bushes but couldn't make it work with a soaker hose. Now I have one of these "bladders" at the base of each bush and fill it up with a hose a couple times a week. Its physical presence also blocks out weeds and covers the roots. I also placed one around a tomato plant in a container that was out of reach from my watering system. Very happy with product

The design is good. The plastic is a bit too thin. Needs to be thicker material. All ready have two holes in one unit. It’s cool. I’m good with it. Just sayin.

A.M. Leonard responds:We are in the process of contacting the customer for more information concerning this issue.

I like the Hydration Rings. I'd like to see smaller ones, maybe 1 gallon size for my container garden. I'd like to be able to use less water when possible.
