‘Tis the season for tree diseases thanks to cool temperatures and rain. Some are serious, others look worse than they are.
The two main springtime invaders are anthracnose, a fungal disease and fire blight, a bacterial disease. Anthracnose creates black or brown splotches on the leaves and it attacks maples, dogwoods, sycamores and oaks. Fire blight causes severe wilting and die-back on the tips of branches and it often affects pear, quince, apple, crabapple and firethorns.
Today’s guest is Chris Starbuck, horticulture specialist for University of Missouri Extension.
