Cognitive system using plant-based data to trigger watering

A computer program product for facilitating plant-initiated triggering of watering, the computer program product comprising:

• at least one non-transitory computer-readable storage medium having computer-readable code embodied therewith, the computer-readable code being executable by a processor to perform a method comprising:
• receiving sensor data from at least one first sensor indicative of water content within a xylem of a root of a first plant for use in determining tensile stress on a first root wall of the first plant;
• receiving sensor data from at least one second sensor indicative of water content within a xylem of a rood of a second plant for use in determining tensile stress on a second root wall of the second plant;
• based on the sensor data received from the at least one first sensor and the sensor data received from the at least one second sensor, determining whether the tensile stress on the first root wall of the first plant reaches a specified threshold, and determining whether the tensile stress on the second root wall of the second plant correlates to there being excess water content in the soil in a region of the second plant;
• and
• based on determining that the sensed tensile stress on the first root wall of the first plant reaches a specified threshold, and based on determining that there is excess water content in the soil around the second plant, initiating moving water from the region of the second plant to soil around the first plant to increase water content in the soil around the first plant.
