Scheduling Homeowners wishing to check when pruning of boulevard trees in front of their property will be down - refer to Team Leader, who will report back to homeowner. Generally deciduous trees are best pruned during the dormant season - preferably early spring before leaves are out. Elms may only be pruned from October 1st - March 31st . This is better for the tree and is also when elm bark beetles, carriers of Dutch elm disease , are inactive. Birch and maple may drain sap from pruning wounds made during winter or early spring.
Evergreen trees require little or no pruning.
If it is necessary, prune in early June. Research has shown that wound dressing does not reduce decay or prevent insect or disease penetration. A very light coating may be applied for cosmetic reasons. Edmonton Community Services Department is responsible for the maintenance of these trees according to Bylaw 7829. We cannot offer advice on private tree disputes.
