The 12 Best Plant Soil Water testers (2023 reviews)

Compared with other tester in this category, the atree plant soil water tester has a design with broader appeal. If you need to know the moisture content of soil you are growing stuff in, like herbs, this does the trick well. This thing is a plant-saver. It can reach deep enough for large tree roots. The dial is perfect since it's just a copper probe and a manual dial. It reads pretty quickly and is mostly accurate.

The probe is long enough to be useful in planter boxes. It is probably most accurate for smaller plants as the probe only goes down about 8 inches and a tree's roots are much farther down. The dial is totally portable, and the probe can be stuck into any pot of soil you desire.
