UnderhillDeep Drip Irrigation Stakes 8-Inch, Watering Spikes for Trees, Flowers, Fruits, and Small Plants, Drip System Tubes, A-DD08-25, Case of 25

These are great for ensuring you're deeply watering newly planted trees. They are also frustratingly difficult to find in garden stores at this size, but are readily available on Amazon at a good price. They are also STURDY for being plastic. When driving the first one in, I broke the HAMMER I was using, but the watering spike was fine. I'll be buying more!

I live in zone 9 in southern California. We made the mistake of planting a young magnolia tree and it didn't die but it didn't grow either. It was in the ground for 19 years and never got bigger or wider. The only water it was getting was from the sprinklers and in the summer months, it would start dropping all of it's leaves. They would grow back over the winter and spring and than do it all over again in the summer. I added three of these 12 inch cones and put irrigation tubing down each and this summer the tree didn't loose leaves. It may actually start growing now.

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.

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....

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!

Received in two days. Order two pieces, one piece without CAP.

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.

Very tight soil here in desert AZ. I drove a length of 1/2 rebar into ground and stirred it around alittle to form a starter hole first before driving tube into root ball. Use a rubber mallot to drive in the tube, so you don't damage top. I use 16" stakes. Water still overflows tubes, but that is OK as I think it soaks from top to bottom. I use as many as five tubes around some of my larger palm trees to get the recommended amount of water to the tree. These tubes are also very good to get liquid fertilizer right down to the roots. I suggest pouring fertilizer a little at a time so as not to overflow tubes. I even drive a few additional holes in the ground to get more saturation, then I fill those holes when I'm done. I suppose you could place tubes in these additional holes and use for fertilizing only, but I think that might allow too much air and bugs into the root system.

Great spikes, easy to put in, and quite sturdy plastic.

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

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.
