There is growing awareness in Connecticut of the damage caused by invasive plants, yet many homeowners, landscapers, and gardeners remain unaware of the serious threat posed by English ivy. Long valued as a low-maintenance and attractive ground cover, English ivy grows quickly, thrives in a wide range of conditions, stays green through winter, and adds a sense of elegance to landscapes. Ironically, these same traits make it especially destructive when left unchecked.
Like other ivies, English ivy is a vigorous climber. Its vine roots secrete a glue-like substance that allows it to cling tightly to bricks, stone, trees, and other surfaces. On buildings, ivy traps moisture, loosens masonry, and accelerates structural decay. However, on trees the harm can be far worse.
