Short summary
We developed a new method using sap-flow and water-potential data to estimate key plant water-use properties without destructive sampling. Testing on drooping sheoak showed that our approach captures seasonal changes in plant water transport and that these hydraulic properties have seasonal variation. This method could improve models predicting how vegetation responds to drought and climate change.
