Q: How do I take an accurate reading?
Insert the probe vertically into the soil about halfway between the pot's edge and the plant stem, going deeper in a large pot and shallower in a small one.
AB928 - Moisture Meter
The best way to make sure you aren't inadvertently overwatering or underwatering a plant is to test the actual moisture content of the soil. Requiring no batteries, this meter has a bi-metal probe that gauges the conductivity of the soil to measure moisture content, indicated by readings from 0 to 10 on the display. By consulting a companion guide, which lists moisture requirements for 170 plant types, you can determine whether the plant needs water immediately, has good moisture, or has been over-watered.
For example, a reading of 4 indicates adequate water for a hibiscus, while a nasturtium (optimum moisture level 7) would need to be watered. The 26 1/2" long flexible cord lets you hold the meter in one hand for easy viewing, while using the other hand to insert the 4 1/4" probe into the soil. An easy, accurate way to assess your plant's true watering requirements.
The moisture meter is also available paired with a pH meter in a set.

Soil moisture usually isn't uniform, and some soils form moisture pockets that can give a falsely high reading in one small spot.
No, the bi-metal probe in this soil moisture meter generates its own reading from contact with the soil, so no batteries are needed.
No, the probe is meant for test readings only; wipe it clean with a soft cloth after each use rather than leaving it in the soil for extended periods.
The included guide lists moisture and frequency numbers by plant name; if your reading is higher than the guide number hold off watering, and water as directed if it's the same or lower.
Yes, they store water and need less frequent attention; from October to February, water them only every two to three weeks, just enough to prevent shriveling.
