Soil moisture sensors
Soil sensors show how much water is available around the roots, so you can water by need instead of by habit.

画像準備中 A soil moisture probe pushed into the ground beside a plant
Soil moisture at the depth of the probe. Depending on the model, also soil temperature and electrical conductivity (EC).
- Install the probe in the root zone of a plant that is typical of the area.
- Press the soil firmly around the probe. Air gaps give readings that are too low.
- Keep it clear of drippers, so it reads the soil rather than the water supply.
