Rated 5 out of 5 by Tree Watering Bags Bags deliver as promised. I ordered 4 of these bags, and installed 3 the day I got them. 2 bags emptied as advertised, one stayed full and 3 days later I dumped it. For what ever reason, I placed the full bag around another tree where the bag had drained fine, and placed it's functional bag around the other tree. At the new location the bag that didn't drain drained fine, and the bag which had drained didn't. I am convinced it is the way I have the rootball and mulch laid out around the tree that doesn't allow the bag to drain. I fixed it, and now all the bags work fine. Point here is I notice some people complaining of not draining, and thought I would provide my experience here. Great inexpensive watering solution!! October 9, 2012
Rated 5 out of 5 by great product -definitely recommend a++ Living in the midwest the second half of our summer is always the same.....heat wave, drought, water ban. The tree bags are a great solution. concept is quite simple. zipper bag onto tree, fill with water, let weep. holds 20 gallons and takes about 5 hours to drain slowly. i wish these were sold in stores to avoid shipping costs and so that i was able to read the packaging in person. One thing that would have been very helpful is to know that the top opening is 4 inches wide....so if you have a larger tree, you can zip multiple bags together to make a larger bag. also, if the zipper is not PERFECT it pops apart while filling the bag and you have to wait for it to drain to realign the zipper. these bags are great, made of a material similar to a tarp, green in color to blend into landscaping, and are a sensible approach to the second half of summers hottest months July 26, 2010

Rated 2 out of 5 by Cheap Zipper pulls apart as you fill bought four and all have the same problem. You would think they would test their product before selling it. Zipper is cheap do not buy this buy the tree gator instead their zippers hold up. September 21, 2011
Rated 1 out of 5 by Good Idea, doesn't work.! I see these being used all over by the local city. I filled mine with water. I came back about 8 hours later and it was still full. I emptied it moved it around and refilled, still full after 6 hours. Emptied and brought to the driveway to investigate, filled it up, and noticed that the factory drilled holes are in the seems, and every time I filled up the bag, the weight of the water pinched the folds where the holes are at, not letting the water flow out. Very poor product, wonder if I just got a defective one where the holes were drilled in the wrong place. DO NOT RECOMMEND! July 2, 2013
