Taffetal on Dec 27, 2015Mine's got it too!!! When I see those black lumps, I either cut off parts or all of the branch, or I slice off the dark lumps with a sharp knife and then burn the spot with the flame of a candle. But the tree is not producing fruit as it did.1 marked as helpful Reply

Deanna.Turetski on Dec 27, 2015Black Knot Disease. If you remove the diseased branches you will have to burn them. Do not throw in garbage as it will spread the disease. I have heard that the tree is history. You have to remove it and burn it!Helpful Reply

Three Dogs in a Garden on Dec 27, 2015Black knot is a fungal infection that often effects cherry, plum, apricot and chokecherry trees. We tried to cut it out of our tree, but it spread anyway. You can try a fungicide to control the spread of the problem, but I fear you may have to cut the tree down and burn the branches.Helpful Reply

Ceres Yurkiw on Dec 27, 2015Black Knot infected our May Tree. We kept on cutting the infected branches but kept on coming back. Last resort, we cut down the tree.Helpful Reply

Sue Fulkerth on Dec 27, 2015Black knot is highly contagious and will also spread throughout a neighborhood to any trees of the same species. It appears your tree is very infected. Sorry, but for your neighbourhood's sake, it should be cut down, the branches contained (bagged or covered somehow) and disposed of (not composted). Burned would be best, but if you can't, the landfill may be your only option.Helpful Reply

Deborah kach on Dec 27, 2015Black knot disease. It will kill the tree. You have to cut off those branches in early spring or late fall and destroy them. It spreads to all berry or fruit bearing trees.Helpful Reply

Diane Basile on Dec 27, 2015Thank all of you. My husband is out there now removing the infected branches. We'll have a tree service take down the rest. It was a gift many years ago from the children for Father's Day, not happy to see it go. :(Helpful Reply

Nancy Evans on Dec 27, 2015Yes. We lost our tree to this smut. Call a tree doctor soon as it will continue to spread. Also, if you lose it don't plant another tree in that spot.Helpful Reply
