Black knot on fruit trees

With the late spring this year and the trees still bare it’s a good time to check your trees for black knot and remove the fungus. It’s primarily affects fruit trees like cherries, plums, chokecherries. The wild chokecherries in our local valley are infected bad and getting worse every year. While you’re out checking your trees it’s also a perfect time to check for tent caterpillar eggs. They’ll be in a 1/2 inch band encircling smaller branches.
