Sap flow sensor apparatus and concomitant methodology for determining the sap flow within plant stems of herbaceous plants and trees using a simplified Stem Heat Balance methodology. Optimum irrigation and utilization of beneficial plant health statistics are enabled using a sap flow sensor apparatus configured with a flexible, sealed sensor layer and multi-layered insulation including an elastic hook-and-loop attachment for enclosing the flexible, sealed sensor layer, soft-foam insulation, a waterproof membrane cloth permeable to water vapor and impermeable to water drops, and an outermost reflective barrier. Based upon the calculations derived from the simplified Stem Heat Balance formula, embodiments afford operational and economic efficiencies due to reduction of the prerequisite electronics to a 1-Channel dT signal.
