Richard Hentschel, host of Green Side Up discusses the severe decline of Austrian Pines due to the kind of weather we have had this spring. Diplodia tip blight favors stressed and older plants. The disease has gotten a lot stronger as trees have remained stressed since the drought of 2012. Treatments are available, yet trees will need 3 sprays each spring and good sanitation to help the pines recover.
