How to care for your Chokecherry Tree in Calgary

Chokecherry trees, scientifically known as Prunus virginiana, are among the most prevalent and easily recognizable trees found in Calgary. These deciduous trees are cherished not only for their beautiful white blossoms that bloom in the spring but also for the small, dark purple cherries they produce in late summer.

Their adaptability to a range of soil types and their resilience in various weather conditions contribute to their widespread presence in urban and rural landscapes alike. However, despite their popularity and hardiness, chokecherry trees face significant threats from a fungal disease known as black knot. This particular fungus, caused by the pathogen Apiosporina morbosa, manifests as dark, swollen growths or galls on the branches and twigs of the trees. These galls can severely impact the tree's health by obstructing the flow of nutrients and water, ultimately leading to dieback and, in severe cases, tree death. The presence of black knot can be particularly concerning for homeowners and city planners alike, as it not only affects the aesthetic value of the trees but also poses a risk to the overall biodiversity of the area.
