Opinion On Moisture Meters
Q: Responding to your column about rocks in pots, I have found that moisture meters are another great way to check soil moisture levels.

You have to be careful with the probes. If you drop the instrument on concrete, the probes can be permanently damaged. But in the right person’s hands, one can be useful.
