The $30 Smart Plant Moisture Sensor That Tells You Exactly When to Water Each Plant
I’ve killed more plants from overwatering than neglect.
Soil looked dry on top—so I watered.
Roots stayed soaked underneath.
Plant slowly declined anyway.
After one too many “easy-care” plants didn’t make it, I tried Amazon’s best-selling smart plant moisture sensor to remove the guesswork completely.
It worked better than I expected.

The app even suggests optimal ranges for specific plant types.
