we just planted a 6 foot high tree. will this probe go deep enough to tell us when it needs watering?

The 1820 will give you an idea of just how wet the soil is in the root ball. All new trees require a fair amount of watering early on so don't let your tree go dry, be sure to water the soil around the root ball also. One thing about the 1820, don't drive yourself crazy trying to hit a specific number, just use it a gauge to determine that the soil is not too wet or too dry.

I don't think so. It's only about a foot long. I only use it for houseplants. I do know if you planted your tree this time of the year, it needs to be watered every day until it gets established if you live in a hot climate.

I haven't tried to make it go deeper than the length of the auger. I suppose it could go deeper, but that would depend a lot on the type of soil. I used it in soils with different conditions, ie. never walked on areas, soil that i heavily mulched over the past 2 years. Thank goodness I don't have much clay, but even the areas where my dogs run around, and pound the ground it worked well. I could not be more pleased with this auger.

Honestly, I don't know. The one I purchased will accommodate up to around a 5 or 6 inch tree I think. It would not work for your application.

It would depend on several things so I cannot as a fellow purchaser give you a definitive answer but will do my best. Research the recommendations for watering the trees in your area first. I used a gallon jug and timed how long it took to fill it with the root feeder in the jug so I could get a gallon per minute estimate for each faucet since not all of my faucets have the same water pressure. Hope this is of some help, if there is a local agriculture extension office in your area they may also be of help. The product has worked very well for the price and I am very happy with mine.

I don't know the optimal water level, but mine works in 7 inch deep of water.

Although I no longer have a lawn to care for, I used these for years to check deep moisture levels for my lawns. The long probe is well suited for this. I would encourage you to purchase at a local hardware store as I have had to return several to find one that works properly over the years. They last for several seasons at best.

Hi Jared, The probe tip is about 5 1/2" from the bottom or 4.25 gal worth of liquid. Hope this helps. Barley & Vine

I do not have orchids, but I would expect that the sensor at the tip is triggering off of moisture in whatever potting material it is inserred into. It did well with reading the moisture at different depths.

I don't know for sure. I just stick it into my compost that is 6 " deep and I get a reading at any depth I place it in.

Sorry I don't but my tree is getting very tall & full & I haven't transferred it to a bigger pot yet.

Ms Sonja, The Luster Leaf 1880 Rapitest meter has probes measuring 3¼". Personally, I would prefer a longer set of probes, it is difficult to measure values at depth greater than 3¼". But don't despair, in most cases one can root down (pun intended) into the root region and pull up a better measurement.Given the price and its accuracy, this tool is a must for most growers and your plants will love the extra attention, perhaps they will "grow like weeds."Happy Gardening and keep on growing, Michael & the Crew @ Synergy Aquaponics

I tried it with 1/4 inch and there is not enough pressure to go more than a few feet. I wanted to do my raised garden. Spent a lot of time piecing it together and the connectors broke as I was setting it up, then it did not work after the first 3-4 feet. I took it apart, plugged the sprinklers into 1/2 inch and was good go to.

Depends upon who tightly packed your substrate is I would guess. My first impression would be, no. The probe is sturdy enough to penetrate deeply into garden or lawn soils, but wouldn't rely on it to survive hitting a rock or hard-packed soils.

It WILL work that way. Some of my 1/4" drip lines sit atop the mulch, some under the mulch and some are 3"-4" below grade. You just have to remember where you buried them so that you do not cut them with a shovel at a later date. The best plan is to create a sketch of your drip watering system, and keep it up to date as you make changes (which you surely will).

It should work. If your soil is compacted, you may want to use some other tool to punch a hole in the soil first, such as a metal rod, long screwdriver, etc. Or loosen the soil with a shovel or cultivator. You want the thermometer to be able to poke into the soil easily, so you do not put excessive force on the gauge.

It is technically possible to extend the line, however I would urge caution in doing this as the drain water will be concentrated in minerals and may cause nutrient lock in plants not suited for high TDS water. It should be fine for use with trees with deep root networks. Please consult with your landscaper or arborist.

My guess is yes only if the soil is loose.The probe is very delicate and may be damaged if used in dard soil.
