A Buyer’s Guide for Soil Moisture Meter

If it were up to us, a moisture meter should be amongst basic gardening tools, along with hand trowel and pruners. It’s so convenient to use and it does a lot by simply telling how moist a soil is! With it, you can avoid over and under-watering your plants, reduce your water usage and ultimately help your plants live! So it’s important that you not only get to choose a good one but be able to maintain it as well. And here are a few tips on how to do just that:

  • Do not use your moisture meter on water or any other liquid for that matter. Many people tend to test their moisture meter on a glass of water, which should NEVER be the case. See, these devices act based on a chemical reaction that happens when the tip of the probe (or the sensor) is placed against the moist or un-moist soil. Only soil. The needle or indicator will move from this reaction and so of course, there won’t be an accurate result if you put it in water.
  • These devices are meant to be used and removed right after – not stay in the pot or ground. Don’t think about leaving it there as it might not work anymore.
  • Be sure to clean and wipe off the probe after each testing so your next reading will be accurate.
  • Be careful when you insert or remove the probe from the ground, especially in a well-rooted or rocky area.
  • If you’re going with a moisture meter with two probes like the Deepow 3-in-1 Soil Meter Kit, be cautious when you twist it while it is still in the soil.
  • To have a more accurate result, stick the probe deep within the soil.

And there you have it! These meters are chosen based on their effectiveness as a soil moisture indicator. Their prices are simply secondary. But, it’s worth stating that they are all VERY affordable. Because hey, why spend more than what is needed, right? Just remember, aside from the quality of the brand you’ve chosen, proper maintenance is the key to not be spending repeatedly for one.

So now our fellow not-so-green thumb, we wish you luck on your adventure and may your plants prosper and live a very long life with the aid of any of these moisture meters!
