Seeing ugly black lumps on your cherry or plum tree? That is black knot, and it spreads. We remove black knot from trees across Edmonton and prune to slow it down, before it takes the whole tree.
Black knot is a common fungal disease that attacks trees in the cherry and plum family, including mayday and schubert chokecherry, which are all over Edmonton yards. It shows up as hard, black, lumpy growths along branches, and it spreads year after year if left alone.
The fix is to prune the infected wood well below each knot, at the right time, and dispose of it properly so the spores do not reinfect the tree. Done early and thoroughly, it can save the tree. Left too long, the whole tree often has to come out.

Black knot is best pruned out in late winter, while the tree is dormant and the fungus is inactive.
Cutting in the dormant season, well below each knot, and destroying the infected wood gives the tree its best chance. Pruning in the growing season can spread spores, so timing matters. If your cherry, plum, mayday or chokecherry has black knot, the sooner it is dealt with the better. Learn to spot it in our guide to black knot disease.
