Corona Tools RootIRRIGATOR – Targeted Deep Root Watering Tool for Trees, Shrubs & Garden Plants, Efficient Direct-to-Root Irrigation

This is an awesome tool - we are going through a mild drought at the moment and purchased this tool as a way to ensure I could take care of my plants while using the minimum amount of water to do so. By injecting water directly to the roots rather than broadcast spraying you can avoid evaporation and wasted water that doesn't perc down to the root zone. I used significantly less water and the vigor of the plants is apparent even in these 90+ degree days. The tool itself is quality - solid steel construction and the fittings are sturdy and leak proof. The comfort grip handles are a nice bonus as well. Hooked to your hose, the tool dispenses a large amount of water, right where you need it, in a very short period of time......just a few seconds at each plant is more than enough. A bargain at the price and a must have tool for any gardener.

Heavy duty, really solid. The shaft has measuring marks so that you can be sure it is in the ground far enough.

There are a lot of low ratings for this product. People mistakenly believe the threads are not designed for US garden hoses. The problem with this product is it is poorly engineered. The inside diameter (the root diameter) of the female fitting on both the shutoff adapter and the waterer itself is smaller than the major diameter (the outside diameter) of the garden hose, so the hose cannot be fully screwed in. The fix is to grind down the thread on male fitting of the hose until it screws in easily. It will seat against the washer for a leak proof seal. There may be some garden hoses, generally cheaper quality, that have slightly smaller male fittings already, which would not have a problem. This is a somewhat irritating problem, but the fix is bench grinder, or a small grinding wheel that fits into a drill, and just go round and round the male nozzle until task is accomplished. The device, other than this, is pretty solid and should last a long time.

Very good

I was a bit cautious when I perfected this product after reading some of the negative reviews. I received the product and it appeared that I would have problems with the valve leaking. However a vise and a pair of pliers had the valve connections straightened out and water tight. Other than that this deep root waterer is perfect! It’s heavy duty, no leaks and made of good thick metal. I use it several times a week and is working well.

It was a gift. The irrigator was placed against a wall on Christmas day 2025. That night it slid and fell on the floor. It broke. The nozzle attachment broke off. It doesn't screw on. Apparently, the nozzle attachment was just barely pushed onto the main portion of the metal body (not screwed on - there are no threads on the main portion) with no secure holding. I tried pushing it back on to no avail. The tool is now useless. Cheap, flimsy nozzle attachment with no way of reattaching it to the main body. So, all I have now is a heavy-duty metal body with no way of reattaching the flimsy nozzle portion. I wouldn't have even given a one-star review but I can't submit this review without at least star.

Really nice unit

Bought this to water our raspberry patch and tomatoes, hoping to cut down on evaporation and wasted water. We encountered two problems. One was a manufacturing issue: the threads were you attach a hose were a little off. It was not easy to attach and we had to use pliers just to get it on and tighten it down so it wouldn't leak. We actually went and bought a short hose just dedicated for this tool so we won't have to hassle with unscrewing it. The second problem had to do with our soil which in some areas has a lot of clay. I was able to get the tool down deep, but a great deal of water bubbled up right around the tool, defeating our goal of preventing evaporation. It worked just as advertised in other areas with better soil.
