American Elm Tree
About 1/3 of the trees found in Regina are American elms. Most of the large trees in the Crescents and Lakeview areas are American elms.
Height and Spread Up to 35 metres in height. Tree canopy can extend up to 15 metres in diameter.
Hardiness Zone 2
Preferred growing conditions Grows best in rich, well drained soil under full sun to partial shade. Drought tolerant.
Form Elms have a tall, vase-shaped outline that spreads into a canopy of branches.
Flower/seeds Seeds are small, disk shaped and papery.
Leaf Dark green leaves are oval shaped, with a pointed tip and serrated edges.
Bark/wood Bark is usually light to dark grey with deep irregular grooves.
You can identify elm firewood by looking at the bark on the cut ends. Freshly cut end shows characteristic reddish brown and lighter coloured layers. In older wood, it may have weathered to a grey colour but will still have lighter and darker layers.
Fruit Not applicable
Pruning Pruning elms is prohibited from April 1 to August 31, as sap from the exposed cuts may attract elm bark beetles which carry Dutch elm disease.
When pruning elms at other times of the year, sterilize pruning saws and shears with methanol (gasline anti-freeze) between cuts and between trees.
