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.... Review: Excellent irrigation tool - 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. ## Features - ROOT WATERING TOOL: The Deep Drip Spikes encourage deeper tree root growth by delivering water, oxygen, nutrients, and fertilizer directly into the soil; conserve water and reduce surface evaporation - COMPATIBILITY: The deep root waterer for trees is compatible with your garden hose, flood irrigation system, or automatic drip irrigation system; Made in USA; from a trusted USA-based company - DURABLE: Made from ABS plastic with mesh filtered holes; the tree stake kit prevents dirt and debris from entering the tube and minimizes clogging; easily move stakes to achieve optimal positioning - SHALLOW ROOTS: Suitable for juvenile or shallow root trees, rose bushes, shrubs, ornamental trees, and boxed trees; the tree irrigation kit is ideal for nursery container stock 5-15 gallons - EFFICIENT: Reduce watering time by delivering water directly to roots; the plant watering spikes reduce surface run-off erosion and prevent the growth of weeds that compete for nutrients ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B00BMK9UR6 | | Best Sellers Rank | #282,137 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #2,832 in Automatic Irrigation Accessories | | Brand | Underhill | | Brand Name | Underhill | | Color | No Color | | Customer Reviews | 4.4 out of 5 stars 393 Reviews | | Global Trade Identification Number | 00857849002005 | | Included Components | 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 | | Item Length | 14.5 inches | | Item Type Name | 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 | | Manufacturer | Underhill | | Manufacturer Part Number | A-DD14 | | Manufacturer Warranty Description | Underhill International offers a 2-year, no hassle warranty for every product we manufacture.

Water eventually soaks through, albeit slowly. I have a slow drip system which dispenses 2 gallons of water in an hour which is slow enough to absorb into the soil and the roots of the plant. Hint for installation. Don't pound them into the ground. I used a 1" auger a predrilled a 24" deep hole and then set the pipe. If you pound them in you'll have a ton of trouble. You'll never drive it 24" into hard soil and you'll damage the pipe and cap trying to do so. **Q: How do you know how long of a spike you need? I have adult citrus trees that are getting hot in Arizona** A: I live in the Phoenix area and attended a very informative seminar last weekend. Trees should be deep watered to a depth of 2-3 feet. After watering, to determine how deeply you have watered, get a 4 ft long piece of 5/8" rebar and shove it down into the ground as far as it will go. When you can't go any further, it means you have hit dry ground. Make a mark, pull it out, and measure. Another great tip: 'if you use a water irrigator spike ( like the Ross root feeder or similar), drive it into the ground at intervals all around the water line of your tree. The ground in this area is so hard that the hole you have created will stay open for years., so when surface watering or when it rains, the water will get straight down to the roots. **Q: What are they made of ?** A: The stake and the cap are made from a very strong plastic. the stake is lined with a fine mesh screen that keeps the soil out as the water seeps into the soil. Depending upon the plant's root structure, I have installed all three lengths. This is an excellent product. **Q: Can the 36inch model be cut down to 24-30inches, and then have the cap be put back on? I am aware they sell a 24inch model** A: Possibly, but you are making it harder for yourself because you'll be getting you drill closer to the ground in the process and possibly getting dirt into it. If buying a 24 inch will work then go with that method. Just my 2 cents. ## Customer Reviews ### ⭐⭐⭐⭐⭐ Seem great so far *by M***E on April 25, 2015* These are better built than I had expected.

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.

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. ### ⭐⭐⭐⭐ These are worth it, with a caveat *by S***N on August 9, 2022* 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. ## Frequently Bought Together - 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 - DEEP DRIP 24-inch Tree Watering Stake (3 Pack, Tan) | UV-Protected ABS Plastic Deep Root Irrigation Spike for Fruit, Flowering, Nut Trees - 14 in.
