• We explore the potential of passive electrical methods to concurrently track water and biochemical fluxes across the soil–tree continuum.
• We test an electro-hydro-biogeochemical conceptual model using electrical potential monitored within the soil-root-trunk continuum at the H.J. Andrews Experimental Forest, Oregon, USA during the summer of 2023.
• Despite disturbances caused by wildfire smoke, electrical signals revealed strong correlations with daily and seasonal tree transpiration, water uptake, hydraulic redistribution, and soil respiration.
• This study presents a framework for using passive electrical methods as proxies for monitoring forest ecohydrological sustainability.
