Take Ivy Off Trees

English ivy can Choke – and kill the beautiful trees that give our yards and neighborhoods shade and character. What looks like a lovely little green plant can actually strangle trees, accelerate rot, attract mosquitoes and cause mature trees to fall down during storms.

Ivy can strangle trees, and once it is in the tree canopy, it can block sunlight from the trees’ leaves. Dense ivy cover deprives the tree’s bark of normal contact with air and mocroorganisms and competes with the tree for nutrients and water. Ivy is a threat. But we can beat it with simple landscaping work.

3 Steps to Remove Ivy from Trees

  1. Use garden clippers to cut ivy at the bottom around the entire trunk of all infested trees. The goal is to separate all ivy vines from their source of nutrients in the soil so they will die. If the ivy is not dense, you can pull it from the soil at the bottom of the tree with your hands, especially the day after it rains.  On heavily infested trees with ivy vines thicker than an inch, you will need to carefully saw through the vine and carefully, gently ease it away from the bark.  Experiment with the tools below to find what works best for you.    TIP: Wear gloves and long sleeves to lessen the risk of poison ivy. Many prefer doing this during the winter months when poison ivy is less virulent, and they will have heavier clothing to reduce the risk. 
  2. Pull all ivy vines out of the ground around the base of the tree, making a 2 feet “life saver ring” around the tree. This will protect the tree from future infestations.  This is easiest to do when the soil is soft from rains; if the ground is very hard and the vines keep breaking, wait until after a rain to remove the vines.  The cleared space allows you to see any emerging ivy from roots you missed.  Arborists suggest laying a 2″ thick leaf or wood chip mulch for three feet around the tree to preserve moisture in the soil and keep lawn mowers from getting too close to the roots.  Keep the mulch 3″ away from tree trunk to ensure air exchange for the bark, and you can spot any ivy trying to reinfest the tree.
  3. Once cut, leave ivy on the tree. Do not pull it off because that could harm the tree. Ivy will gradually blend into the tree bark after it is cut.  Check up your tree each winter to be sure the ivy remains off.

    We have two beautiful old oaks on the property line between our home and our neighbor’s home. The trees are closer to our house than theirs and have been neglected to the point that there are ivy vines with 8″ diameters. We were given permission to remove the ivy because everyone is in agreement that the trees are in danger. We have severed the ivy ‘trunks’ but I am worried that the ivy is so old and dense that it has developed a root system higher in the tree than we can reach.

      I work with a group—the No Ivy League—in Coastal Northern California that is working to get rid of English ivy in our State Parks. A main priority for us is to liberate the numerous trees (Sitka spruce, Redwoods, Alders, etc.) that are being engulfed in ivy—some with large stems like you describe. Once you sever the stems around the trunk, the ivy will dry up pretty quickly. While some ivy stems may have rooted in the crotches of the tree in some places, it’s doubtful there would be enough soil to sustain ivy to the degree that it is being sustained from the ground. The very best thing you can do is cut the ivy stems around the tree and watch, with satisfaction, as the ivy drys up and the tree is liberated from the strangling effects of the ivy.

    • TreeStewards says:

      Never fear, Bobbi. Ivy on the trunk will die if at least one foot of growth between the ground and what remains on the trunk is both severed and very gently removed from the bark. Some folks like to cut ivy at the base of the tree, clearing the “life ring” from the base, and then standing up and cutting all the ivy at chest height, very gently the ivy stems downward and off the tree. The idea is to make the cut so large that the ivy will not regrow into its remnants on the tree. If ivy loses contact with the ground, it will die. It may take awhile, but it will happen. Check your trees annually and remove any new growth.

    Thanks so much for the informative article. I have pulled ivy off trees now knowing the harm I was causing. What ground cover that is not harmful to trees would you suggest instead of ivy down slopes that also house trees? We also have dogs so hopefully somewhat sturdy ground cover that would keep the soil for the trees on the slopes.

    I did as you told above and within just two days all of the vines have wilted and look to be dying quickly. I had previously cut the vines, but it didn’t quite work. I ripped out the roots after a big rain about 1 foot away from the tree. I’ll be adding mulch soon. The oak tree has been shedding small twigs off the ends of the branches, a sign of stress, so I wanted to move quickly on killing the vines. I was grateful that you recommended a way that doesn’t involve chemicals. I am a resident of DC and would’ve had to call a tree doctor soon if I couldn’t take care of this myself. Thanks for the huge help!

    Black poplar laden w/ thick English ivy:
    Once I clip the numerous thick 1″ thick vines at the base of this 75-100 year old black poplar, given the tough thick bark of the tree, do I leave the vines on or pull them off the trunk?
    I tested by pulling one vine and it did not seem to pull any bark. I am concerned about the upper bark being thinner. The local arborist said ok to pull as this bark would not cause harm. Feedback welcomed.

    • TreeStewards says:

      Oops, sorry we overlooked your question. You were correct to carefully check the bark when first removing as the bark is like the skin — you don’t want to damage it. We generally recommend leaving the vines/ivy growing once cut and they will dry out and be blown away. Also, we’ve seen some folks who really, really tug on the vines and can do significant damage to the bark. Our general way to ensure all ivy vines are removed from 3 foot height to the ground so we can be sure every vine is removed. Sometimes one overlooks one vine and the ivy keeps alive a year later…then we have to go back and make sure to get it all.

      As long as you keep checking the bark is not coming off or being ripped, you are ok. Glad you’re doing this!

    Thank you for the article. We just moved into a house in Ventura CA, and there is a beautiful flowering tree (unidentified at moment) that is strangled by ivy. The base of tree has very large old ivy vines around it and it is completely entangled above in the canopy. The tree is still flowering and seems healthy so I will work on it at base immediately, and over the next year I will gradually attempt to remove the dense vines above. Who knew you could get a rash from this type of ivy! Thank you for informing me. I removed some vines the other day and now wonder if the slight rash I have is from the ivy.

    Thank you for reminding us of the goal:right tree for right place, right garden for right place.

  10. I agree with DC Arborist. We’ve lost a great deal of canopy cover throughout the US. We can start at home by maintaining the old growth trees we have and adding trees where appropriate.

    Also, when thinking about ivy’s impact, also consider eliminating solid canopy cover so gardens can grow……..massive tree canopy prevents sustainable urban agriculture and healthy nutrient initiatives.
    Maintaining vegetable gardens and committing to dense canopy shade are divergent and contradictory objectives

    • DC Arborist says:

      Tree canopy and gardens do not have to be mutually exclusive. Just follow the rule: right tree for the right place, right garden for the right place.
