Underhill Deep Drip Irrigation Stake 14-1/2-Inch, Watering Spike for Trees and Bushes with Shallow Roots, Drip System Parts Tubes, A-DD14, Single

These are better built than I had expected. There is a screen inner liner behind the holes, which prevents the tube from filling with dirt. I got the 2-footers as I thought that I would have trouble getting a 3-footer in the ground. Pounding them into the ground was a challenge - they went in OK, but the instructions say to pound them in with the lids on. I did so, and then I couldn't get the lids off. Sometimes with two pipe wrenches I could get the lid off while the stake remained in the ground. Other times I would have to pound them in, pull them out, put it in a vise, pull off the lid, put the lid back on, then pound it back in the ground down the same hole. Eventually I got all 8 of them in, and probably should have gone for the 3-footers. There is a convenient slot near the top where you can run a 1/4" drip hose under the lid. My system at the moment has one drip hose at the base of the tree (on top of the soil) and a second going down to the bottom of the spike. I've only had this setup for two months now but the trees are liking it so far....

These things work great. My new saplings started showing improvement immediately. They were easy to get into the ground and even when it rains, they help absorb the water even deeper into the ground. I use 2 per small tree and watch where the water disperses and then move them if necessary to ensure uniform irrigation. I add a slow drip hose to each hole for a few minutes and then turn on the soaker hose around them to get the feeder roots as well as even more deep watering as the spikes absorb the surrounding water. These are a must have for strong establishment of new trees as well as deep irrigation for already established specimens. Roots go where water flows.

I really wanted to be able to just stick a hose in the top and deep water that way, but water sprays out from the side holes, and the top. I just could not get a good enough seal by holding it, and there was no way to hook the hose up to it. I really, really, did not want a water line going up the side of a very large planter with a tree in it, but that is what I ended up doing, I purchased two, one for each side, put a drip line in each, and it seems to be watering very well. It is just an aesthetic thing for me, so I've gotten over it. However, I did take off a star because the product info make it look like a hose can go on/in this thing, and unless I am doing something so very wrong, it does not, plus the water spraying out of the side holes defeats the purpose. Also, a standard drip line was too thick to go in the side holes and work well, so I had to run them from the top, using the side slot. I think this watering steak offers enough solutions for the right application, you just have to have that particular equipment to make it work the way you want.

I live in a hot and dry area and run a lot of water to fruit trees and other trees on my property. Previously I had multiple drip lines on each tree. As you can imagine, the results were mixed. A lot of water evaporates and little penetrates to the roots unless you run the system for a long time. I first found these at a big box store and tried them on three trees. Huge improvement! My ground is very hard, but I used a large drill bit to start a hole and then hammered these in using a sledgehammer. I removed the caps before hammering. You can hit them hard without breaking them. Running water into the hole helped, too. Once in place, these things work great. I went on Amazon and ordered a bunch more. I now run my system shorter and get more water to the roots of the trees. I am already getting better/more fruit and seeing healthier trees. Awesome.

Excellent quality, made in USA., heavyweight plastic. I wish more products were made as well as this. Simple and effective. My only concern is if it could clog over time. There are small holes inside each of the larger holes, so hopefully that keeps it from clogging. Should be easy to connect almost any type of watering tube. You just stick your flexible tube into the top and done.

They were of good quality but wasn’t impressed with their performance!

We have sandy top soil so when I try to water my trees with a drip system the water just beads off and rolls downhill. I drove two of these into the ground and they are able to get a lot more of it into the ground. I was worried I was going to break them when hammering them in to the ground, but they are very tough and went in easily with a rubber mallet. I was surprised how easily they penetrated the ground. 5GPH was too much for my soil so they leaked out the top. I went down to 2-3 GPH and almost all of it absorbs into the ground now. My myoporum trees no longer look like they are dying and have a lot of new leaves growing, and actually have white flowers coming back now!

We are in a 20 year drought out here and my maple tree was definitely showing signs of stress. I bought a few of these and connected the hose to a 60 gallon barrel and I fill the barrel up a few times a week. The tree is improving and the water goes into the ground for the roots and not on top watering the weeds.

Easy to install. Just hammer home, ground sucks up the water through these. Great product.

awesome product and very happy with it.

Not all the item was delivered. the cap was not in the box.

excellent product for excellent price. shipped and delivered very fast- A++++ experience- thanks! haven't used it long enough to notice a difference in my trees yet but am excited to see the results based on other reviews. We are using a garden hose with these stakes.. Already had a tree berm in place (as recommended) but it is currently soil and mulch but I am going to get landscape edging to do a nice round and make it more esthetically pleasing

Solid construction, held up extremely well to being driven into dirt with lots of clay. The irrigation holes are properly meshed over as well, preventing dirt from getting into the spikes. I bought several for a fruit trees and am happy with them so far.
