Soil Moisture Gauge for Potted Plants

A soil moisture gauge for determining a level of moisture in a plant pot has an elongated main body, which has a lower tip and grooves formed in and along the main body. A graduated scale is formed in the main body over a distance corresponding to a maximum expected soil depth when the gauge is inserted into soil contained in the plant pot. When the gauge is inserted into the plant pot and then pulled out of the plant pot, moist soil is retained in the grooves whereas dry soil falls from the grooves, whereby a user can read moist soil depth on the graduated scale. The reading from the soil moisture gauge can be used as an input to a system to adjust a drying profile that indicates to a user a time by which the plant should be watered.
