Similarly, you may ask, do moisture meters work for plants?

Cheapo moisture meters are next to useless at telling you how wet/dry your plant's soil is. They measure EC (Electrical Conductivity) and are far better at telling you how much salt is in the soil than how wet it is. If you doubt - try probing a glass of deionized (distilled) water. The meter will read dry.

Also Know, can you leave a moisture meter in the soil? 1. Do not leave the metal part of the tester in the soil for too long (no longer than one hour) or it will damage the metallic surface. 2. Make sure the metallic surface is clean and dry before storing.
