Black Knot Trimming in Edmonton & Surrounding Areas

Targeted removal of black knots, damaged limbs, and decaying branches that threaten your trees' health and your property's safety. Preventative care that saves you money down the road.

Don't Wait for Dead Branches to Fall

Black knots and dying branches are more than ugly — they're dangerous. A heavy dead limb can drop without warning, damaging your roof, car, fence, or worse. Edmonton's harsh winters, wind storms, and freeze-thaw cycles accelerate the problem every season.

Dead wood also invites pests and disease into otherwise healthy trees. Removing black knots early is one of the smartest investments you can make in your property. AJS Slashing specializes in identifying and safely removing dead wood before it becomes an expensive problem.

FAQ

Black Knot & Trimming Questions

What Edmonton homeowners ask about black knot

How much does black knot removal cost in Edmonton?

The cost depends on how many trees are affected, the size of the trees, and how widespread the infection is. We give a free, no-obligation quote once we've seen the scope of the problem.

What is black knot?

Black knot is a common fungal disease in the Edmonton area that forms hard, black, swollen growths on the branches of chokecherry, mayday, and other Prunus trees. Left untreated it spreads through the tree and can eventually kill it.

How do you treat black knot?

We prune out the infected branches well below each knot and dispose of them properly so the spores don't spread, sterilizing tools between cuts. Catching it early and removing all the galls is the key to bringing it under control.

When should black knot be removed?

The best time is late winter or early spring while the tree is dormant, before the fungus releases new spores in wet spring weather. Removing it then gives the tree the best chance and limits how far it spreads.

Can black knot kill my tree, and will it come back?

Yes — left untreated it weakens the tree and can eventually kill it. It can also recur, so after removal it's worth checking the tree each year and trimming out any new knots early.
