Leonard ArborRain Tree and Shrub Hydration System, 20 Gallon

Leonard ArborRain™ Tree and Shrub Hydration System, 20 Gallon

Slow, even watering means maximum usage by the tree.

ArborRain provides a great alternative for deep watering of newly planted trees and shrubs, helps to minimize "transplant shock", and helps established trees better withstand hot, dry conditions. High capacity 20-gallon model releases water over a 5 to 8 hour timeframe allowing water to permeate deep into the soil, hydrating both root ball and surrounding soil for complete coverage.

ArborRain is designed with a low profile to blend in better with the natural surroundings and the dark brown color dramatically reduces its visibility when used along with dark hardwood mulches. Fits up to 6-inch diameter trees. Multiple hydrators can be placed around the drip line of large established trees to alleviate stress from drought or new construction. Use ArborRain to protect your new tree investment!

    4 Stars For an arborvitae not perfect. . .

    from MI wrote :

    I used mine to water a newly planted arborvitae. I also had purchased another style of bag for other trees at the same time. This one is better than the others because I feel like I'm getting a better measurement of water. However it is somewhat awkward to fill for two reasons one that is a design flaw? and one because of my application. The flaw is that you have to hold your hose in place and then lift the fill spigot as the bag fills with water so that the water doesn't come out of the top before it's actually full. The other problem is that this will work much easier on trees and shrubs with higher branch systems. You will also want to rotate the bag periodically so you don't develop a washout channel.

    4 Stars Certainly helped

    During this drought I was looking for something to help on the days that I could not give my young trees a good soaking. Easy to use, except for the cutout that is supposed to fit back over the cap? Quality is ok, but the velcro connect strap has already come off on one. Be interested to see how they hold up.

    4 Stars ArborRain Hydrator

    from NE wrote :

    For newly planted trees, I liked the slow dripping to water the tree. After a hot summer, my newly planted trees look good.

    3 Stars A product for flatlanders

    from MT wrote :

    This product would be great if your tree is perfectly level. If the Arbor Rain is placed on a hill, it rolls down the hill in addition to being difficult to fill since you have to hold the opening up in the air while filling.

    4 Stars AR20

    from AZ wrote :

    So glad I bought ten - shoulo have bought more. They are easy to fill and move if needed. I have three fixed, the others serve more than one tree. Wish they sold a gadget to hook up the AR20 to a quick-connect garden hose. But even with tired knees filling these things, I'll still use them because I can count on a specific amount of water going to each plant with minimal evaporative loss.

    5 Stars It does what I need it to

    from AR wrote :

    Hot summers with no rain really stress plant life here. Bought the AR20 specifically to care for a Japanese maple that suffers every year during hot weather. The AR20 allowed water to get directly into the root ball without excessive evaporation, and with 3 fill ups a week our maple looks better than it ever has.

    from IN wrote :

    worked very well for the purpose intended

    2 Stars drains too fast, hot water in full sun

    from wrote :

    The idea of a slow drip is good, but this 20 gallons is empty within 5 hours, so I felt it was not really very slow. I found it easier to put a hose on with a trickle where there was access. Also in full sun & 100 degree temps, both the plastic & water can get quite hot...not so sure that's great for newly planted roots. It wasn't the best solution for me.

    5 Stars Great product

    from TX wrote :

    This watering tube worked great for me in the ongoing Texas drought. It does a great job of soaking down the root zone slowly. I have had no problems at all with the AR20 product. I was concerned that wildlife such as raccoons, etc. might be a problem in this extreme drought, but they did not bother the tubes at all.

    4 Stars Winter Watering!

    from CO wrote :

    This product is a must have for establishing trees in dry climes. After the irrigation is shut down we had to have a way (other than with a hose) to provide water to trees and shrubs. We use each variety of the "water bags" at my company, and love them. We sell one with every tree/shrub we install. My only complaint is, like the others, there needs to be a hose bib with a one way valve on the cap!

    4 Stars Drought Buster

    from NM wrote :

    We needed a solution to help keep ahead of the drought that we are experiencing. This product provides a deep, slow watering that keeps the roots down deep in the ground. Our apple and spruce trees are flourishing whereas surrounding trees that are not irrigated with this product are not.

    4 Stars Works as advertised

    from MD wrote :

    I bought these to you around our newly planted plum trees. After using them for a while I realized that a soaker hose is just as effective if you have enough hose to reach your connection. These may be better suited to remote plantings when you have access to a trailered water tank since you have to fill them in place. I agree with the other posters that a quick-connect cap or other hands-free filling method would be nice. They work as advertised, but you may not need them.

    4 Stars AR 20

    from MI wrote :

    I think the AR 20 is the perfect size. I was able to water my trees on a schedule and only once a week all summer fit around the trees nicely and it was a lot easier than dragging a hose or a sprinkler sround the yard! The only downfall I saw was that if the ground around the base of the tree was not completely level the bag would not drain fully.

    3 Stars ArborRain doesn't live up

    from OR wrote :

    In general this is a good concept, and one I like better than the upright green hydrators. However, I was disappointed that the material isn't more durable. Since it is placed on the ground, the ArborRain is vulnerable to puncture by roots, sticks and rocks. Which is exactly what happened the first time I moved mine. If the material were stronger and more durable, this would be a great product.

    4 Stars Good Product

    from MS wrote :

    It works well but there are several small problems. It does not completely empty making it hard to move and there needs to be a ridge or handle to keep it open when filling. I have not yet filled it without getting wet.

    4 Stars Looks great, works great on flat ground

    from OH wrote :

    The flat design is a great leap forward. Its low profile makes it barely noticeable, even when full. If ground is not completely flat around the tree, I recommend the upright version.

    4 Stars Almost perfect solution to my needs

    from CA wrote :

    I walk with 2 canes and cannot touch my toes, let alone anything at ground level. I learned that my pomegranite trees might bear better if they had more water whenever they have bloomed. My idea was to hook up a couple of Arbor Rain "donuts" around the drip line. (I added a bit of citrus tree food for good measure.) My plan included attaching 10 foot length of hose to each then to a splitter with a quick connect to the hose. I devised a way to adapt the cover for the fill hole to thread in the hose end and proceeded. At the end of the season I should know if that does indeed fix my problem with having my pomegranite blossoms drop and fail to produce fruit.

    4 Stars Arbor Rain System

    from AZ wrote :

    This is a great all around product for watering trees where irrigation systems are not present. I have my guys use these on newly planted trees. I think the only drawback on them is filling them with water. If there was a product that you could connect to your hose and then connect to the Arbor Rain bladder, I think it could expedite the process. Then it could be hands free.

    5 Stars Watering a Redwood Tree

    from CA wrote :

    In our California native plant garden, we have a Redwood tree that in the past got little soaking water. With the ArborRain, it now gets adequate water at a slow rate.
