Why is ivy bad on trees?
The added weight of the ivy can cause mature trees to come down in a storm. For example, on a large tree in Olympic National Park, 2,100 pounds of ivy was removed from a single tree.
• Once ivy is in the tree canopy it shades out the trees leaves or needles.
• English ivy can strangle a tree, especially at the base of the trunk.
• Dense ivy cover deprives the tree's bark of normal contact with air and microorganisms.
• Thick ivy mats accelerate rot.
• Fast-growing ivy competes for nutrients and water.
