Houseplant hacks: do moisture meters prevent overwatering?
Given how easy it is to kill plants by overwatering, these devices are tempting – but can they beat simply sticking your finger in the soil?

TL;DR
- Houseplants frequently die due to overwatering, not neglect.
- Moisture meters estimate soil moisture by measuring electrical conductivity.
- Accuracy of moisture meters can be inconsistent, particularly in small pots.
- Traditional methods like the finger test, pot weight, and plant observation are also important.
- Moisture meters can serve as a confidence booster for overwaterers but are not infallible.
