Summary:Key message Use of co-occurring species with varying temporal sensitivities to summer soil moisture may be used as a diagnostic to determine summertime drought intensification or amelioration. The use of tree-ring data from co-occurring species with different summertime soil-moisture responses provides an opportunity to evaluate the occurrence and direction of soil-moisture changes. Here, we present a method that compares adjusted latewood growth between longleaf pine ( Pinus palustris Mill.) and chestnut oak ( Quercus prinus L.) from 1969 to 2018 in the Uwharrie Mountains of central North Carolina, USA. We found that adjusted latewood sensitivity to soil moisture varied between species with the strongest response in September PDSI for longleaf pine ( r  = 0.47), and July PDSI for chestnut oak ( r  = 0.61).
