Trees

Trees are a vital part of Fort Saskatchewan’s urban landscape, offering shade, beauty, and environmental benefits. The City manages public trees through planting, pruning, and disease prevention programs, while residents are responsible for trees on private property. Learn how to identify tree ownership, report concerns, and support healthy tree growth in your neighbourhood.

If you are concerned about a hazardous tree falling on a powerline, please contact Fortis Alberta or call 310-WIRE.

Tree Ownership

The strip of land at the front of your yard, usually the first 3 metres from the sidewalk or curb, may be City property. Trees in this area, or in nearby boulevards and green spaces, are typically owned and maintained by the City.

Residents should avoid actions that could harm these trees, such as root pruning, chemical use, or removal. Damaging roots can weaken the tree, cause unwanted growth (suckers), or make it unsafe during storms. If you're unsure who owns a tree, trace the roots to the trunk or contact the City for help.

Trees on private property are the homeowner’s responsibility. If you’re concerned about a hazardous tree on City land, please report it through Fort Report.

Tree Roots on Your Property

Tree roots growing into your yard can be frustrating. They may come from a tree on your property, a neighbour’s, or City land. Roots can push through lawns or get close to foundations.

Before removing any roots, check if they’re still connected to a tree.

  • If not, they may be leftover from a removed tree and could grow suckers (small trees). Mow or prune suckers regularly.
  • If yes, find out who owns the tree before taking action.

You can request a visit from a City arborist through Fort Report to help determine ownership. Please note: City arborists cannot remove trees or roots on private property.

What's wrong with my tree?

Dutch Elm Disease is spread by Elm Bark Beetles, which feed on healthy elm trees and breed in dead or dying ones. Once infected, an elm tree will die within a year.

To prevent DED, follow the provincial pruning ban from April 1 to September 30. Pruning during this time can attract beetles to fresh cuts and spread the disease. If you prune before April 1, make sure branches are burned, buried, or chipped by March 31.

You may notice brown plastic panel traps attached to trees around the city. These are Elm Bark Beetle traps placed by the City to help monitor and protect elm trees. Please do not touch or remove them.

Report all suspect DED infected elm trees immediately to the STOPDED Hotline at 1-877-837-ELMS (3567).

Black Knot is a fungal disease that can spread quickly and kill trees if left untreated. The City recommends pruning, not chemical sprays, to manage the disease.

If your tree is infected:

  • Prune affected branches between late fall and early spring when knots are easier to see.
  • Cut at least 15–20 cm (6–8 inches) below the knot.
  • If the knot is on the trunk or a main branch, cut 1 cm (½ inch) beyond the edge of the knot into healthy wood.
  • Sterilize your tools between cuts using bleach.
  • Dispose of infected branches immediately. Place them in a plastic bag and put them in your black garbage cart. Do not compost them.

If there is a suspected case of Black Knot on a tree on City property, report it on Fort Report.
