Episode 12: Fireblight. And Persimmon Passion!
Fireblight is a deadly bacterial disease that has been spreading through large parts of North America in recent years. If you don’t catch it early on, this disease can not only kill your tree, but it can also spread to other trees nearby. And yet the early symptoms look pretty innocent – leaves go brown at the tips of the tree’s branches and sometimes the branch curves into a hook shape.
You might think your tree just needs a little more water. But fireblight is far more serious than that.
Later in the show we learn about persimmons, an unusual fruit that some love and others hate. As it turns out the success of your harvest depends on which varieties you plant.
