English Ivy on Pine Trees: A Deadly Combination

Does ivy climbing pine trees kill them?

Yes—Ivy Smothers and Weighs Down Trees

Vines block light to needles, killing foliage.
Added weight bends or breaks branches.
Ivy retains moisture against bark, promoting rot and disease.

Management

Never plant ivy at the base of trees. If already present, cut vines at ground level and remove from trunk. Do not pull heavy vines down—let them die and fall.
