Dethatching when lawn has dise

Post by Sod » August 28th, 2022, 3:18 pm

Is it OK to dethatching when my lawn has both brown patch & red tread diseases. I have treated ( later than I should have) the lawn with both Heritage G and DiseaseX but the disease areas are still very evident. We have also been in a draught since the first of June but have gotten rain since mid August with more predicted for tonight?
