This straightforward, easy-to-read, inexpensive moisture meter stays in the soil with its partner plant. Bury the sensor tip to the soil depth you want measured. When you water the plant, the pF indicator will turn blue. When the soil is dry, the pF indicator will return to white. Simple as that! Each indicator lasts about 6 months. Grab refills here.
