Question From: C. Rooker - Linwood, Kansas, United States
Q: You state that Boston Ivy will not harm trees. Other people have told me that it will kill a tree if it is left to grow up the tree. What is the source of the information you print that Boston Ivy will not harm trees? What I thought I have growing up my Oak tree is Boston Ivy or maybe not. It is non deciduous, the leaves are very dark green and the veins are light green, leaf is about 3 inches long, has a rounded point at the end and each side has one or two slightly rounded protrusions. What do you suppose it is?
Carol, Cut off some of the leaves and take them to your local independent nursery for an accurate ID. Boston Ivy looses it's leaves in winter and will not harm trees. English Ivy retains its leaves in winter and can cause problems if it gets into the canopy of the tree. Jeff Ball wrote that entry several years ago and he has passed away, so I can't quote you his source. However I just e-mail a professor of horticulture from Delaware Valley College of Horticulture and he agreed Boston Ivy will not kill a tree. If you are in doubt remove the ivy. Best And Happy Yardening, Nancy.
