New Easy Fill Cap 15 Gallon Slow-Release Tree Watering Ring - Slow Release Watering Ring - Tree Irrigation - Plant Irrigation - Garden Irrigation - Watering Donut

The main picture does not show the fill port which is very strange but it was on top as expected in the product received. Some other pictures did show it so although a bit concerned I bought two. It has a screw cap that works easily. There is also a flapper just under it to hold the water in while putting the cap on. Works very well but at times I needed to use my finger to pull it up near the opening. The cap is tethered which is very nice to have. Empties in about ten hours, but feel that is o.k. for my young maple trees.

This is great for newly transplanted trees. We previously ordered a tree watering device that stood up, and nearly toppled over our newly transplanted trees. I realized after one attempt that it wouldn't work for several years. This one is perfect for several reasons:Pros: Easy to wrap around the tree, easy to fill up, appears to last several hours (I have not timed it, but it was mostly empty after 6 hours), and includes a tab with a hole in it, allowing it to be more easily filled. I have also contemplated using a stake in this hole to prevent it from blowing away when it is empty.Cons: The opening is difficult to close, and on a slope, the water does not empty completely as the valves are more or less centered within the ring. However, the remaining water makes up maybe 1/6th of the total volume. Another potential problem was our outdoor cat. When we got him he had been declawed (but refuses to live indoors). He had been attempting to "massage" the full ring with his clawless paws (he really enjoys the boyancy). I worry a fully functional cat may be able to puncture this. Just a thought.

We had a new tree planted and this watering ring helped us keep it hydrated and healthy during its first few weeks after being planted.It was so convenient: fill it up and walk away.No need to stand there watering. The tree received a nice steady stream of water over a few hours. Fabulous invention.

This is a well-made product and seems very sturdy. Has held up to the sun, rain and other elements. But the design is flawed for our purpose. We have a very large yard and I bought it to water a couple of fruit trees that our hose can’t reach. The trees are on sloped ground. The “donut” only has two water spouts (one at either end) so no matter which way I turn it one of them is positioned below the tree and runs straight down the hill. Given how hard it is to drag it down there (it’s so heavy!) the design defeats the purpose and Hardly makes it worth it. Would love to find one with more water “spouts” (holes?) evenly spaced along the bottom...

I recently planted several 8 foot Norway Spruce trees in my yard and the garden center who installed them said to trickle feed them. I thought these rings would be a good option but they did not work out at all for me and I can only see them working in ideal conditions where the ground is completely flat and you have full unobstructed access to the base of the tree. The Spruces we planted are easily 6 feet in diameter at the base, and being conifers, of course they have long branches with long needles low to the ground. It was literally impossible to get the ring around the base of the tree without kinks and twists that prevented it from filling up. Also, the ground we planted on was not flat and had a slight slope to it. So when I tried to fill the ring, as soon as the water level equaled that of the slope, the water started pouring out of the fill hole instead of filling the rest of the kinked and twisted ring. I got the ring about half way filled (the side that wasn't all twisted) and tried to put the plug into the fill hole and it was nearly impossible to get the plug back in. Trying to do so resulted in half the water I just put in spilling out from the pressure I needed to apply and the fact that the ground is slightly sloped. Maybe these would work for deciduous trees where there are no branches at the base, and the ground is completely flat. Another reason I decided not to give these another try is after talking to the tree expert at my Garden Center he mentioned these rings will drop the entire 15 gallons of water over roughly an 8 hour period and that may be too much both for the tree and for my well considering that I would need to refill 10 rings a day @ 15 gallons each.

Easy to use and it works well.

The spout broke after the first use

So my usage of this product is not like most. I am not using them to water trees. I am in south east Texas and we have not had much rain this year. Our ground is 90% clay so we have giant cracks and shifting ground. In order to keep fence post in the ground and my gate to stay level, i use these to water the posts so they do not shift. So as other said, the bags do get hot when empty and probably would hurt a young tree i dont care about dead grass. I got 2 and it does seem that one releases faster than the other and i am not sure they really hold as much water as they claim, but they hold more than my 5 gal bucket so i am happy.
