How do we get English ivy and other climbing vines off the trees on our HOA common areas?

By OurHOA · General information · Revised

How an HOA board gets English ivy, wisteria and other vines off common-area trees: the cut-and-ring method, herbicide timing, TX, FL and CO rules, and a motion.

Part of the HOA board handbook: vendors, projects and upkeep.

The short answer

Cut every vine at the base of the trunk and again at about eye level, peel off the band in between, clear a ring of bare ground around the tree, and leave the upper vines to die where they are. Come back in spring for regrowth. Do not pull green vines down out of the canopy, and do not put anyone on a ladder leaning against a vine-covered trunk. Which vines you are fighting depends on where the community sits. English ivy is the textbook tree climber, but the USDA Forest Service's species review says it is most invasive in the Pacific Northwest, and that Texas floras describe it mostly as an ornamental around homesites that sometimes escapes into woods. Texas and Florida boards are just as likely to face wisteria, Japanese honeysuckle or climbing ferns, and Colorado boards face Chinese clematis. The cutting method works on all of them. Weed and herbicide rules vary by state, county and your governing documents, so treat this guide as general education, not legal advice.

Why vines on trees are a board problem

A few strands of ivy on a trunk look harmless. A tree carrying vines into its crown is a different matter. The Forest Service review reports that ivy can cover and kill branches by blocking their light, that trees hosting it may be more likely to blow over in storms, and that the extra weight of water or ice on the evergreen leaves may add to storm damage. It also names English ivy as a host for bacterial leaf scorch, a disease of elms, oaks and maples. Wisteria is worse. The Texas Invasive Species Institute says Chinese wisteria climbs in a counterclockwise spiral, can kill sizable trees, and that vines left coiled around a trunk can girdle it. Its page on Japanese honeysuckle notes that the trees and shrubs it climbs can be pulled down once they die. A trunk wrapped in vines also hides cracks, cavities and fungus from whoever inspects the trees. Our guide on how to plan an HOA tree maintenance program covers that walk and the pruning cycle. Last, climbing vines are the ones that spread. The Forest Service review says English ivy typically flowers and sets seed only after it climbs into light, and that birds carry the seed. Ivy on the ground rarely fruits. Ivy at the top of an oak seeds the whole neighborhood.

Know which vines you have

Walk the common areas in winter, when evergreen ivy stands out on bare trees. Number each vine-covered tree on the site map with the species and how high the vines reach. Texas: the Texas Invasive Species Institute lists English ivy, Chinese wisteria and Japanese honeysuckle as present in the state. Honeysuckle resprouts after its stems are damaged, so the institute warns that one treatment will not clear an established patch. Florida: UF/IFAS Gardening Solutions marks Japanese honeysuckle, Old World climbing fern, skunkvine, cat's claw vine, air potato and kudzu as prohibited, and Chinese wisteria as invasive. It says the wisterias can shade out and kill trees. Air potato and other Florida invasives have their own guide, on how to remove invasive plants from HOA common areas in Florida. Colorado: C.R.S. 35-5.5-108 sorts state noxious weeds into lists. List B species must be eradicated, contained or suppressed in the parts of the state the agriculture commissioner designates, and a county or city may set a stricter standard. Chinese clematis is on List B, and Jefferson County requires eradication there. Look for a woody vine on fences and trees with yellow, bell-shaped flowers from late June to August and feathery seed heads. It is hard to tell from native clematis without flowers, so ask the county weed office to confirm before you treat.

The cut, step by step

Clemson's Home and Garden Information Center and Oregon State University Extension describe the same method, sometimes called the life saver ring. 1. Cut every vine around the trunk at a height the worker can reach standing on the ground. Clemson suggests prying thick vines away from the bark with a large flat-bladed screwdriver before cutting with pruners, and using a saw on the biggest ones without cutting into the trunk. 2. Pull the vines below the cut away from the trunk and cut them again at the base. 3. Clear ivy off the ground in a ring around the tree. Oregon State says at least 3 to 5 feet out from the trunk. 4. Leave everything above the cut in place. Oregon State says ivy left in the canopy dies, does little harm and no longer makes seed, and the dead stems fall off over several years or in winter storms. Pulling it down risks tearing bark and drops debris on the crew. 5. Bag or haul the cuttings. Oregon State says not to compost ivy at home, and to stack cuttings roots up if they have to sit on site for a while, so they do not take root. The Texas institute warns that stem pieces left on soil can resprout. Clemson says the work can be done any time of year. Budget the labor honestly: the tree in Oregon State's photos took two people about two hours. Clemson also notes that ivy sap can cause a rash in sensitive people, so everyone wears gloves and long sleeves.

Herbicide for regrowth and ground cover

Cutting stops the climbing, but roots send up new shoots and ground ivy creeps back. Timing matters more than product. Clemson explains that older ivy leaves carry a waxy coating that keeps herbicide out, while new spring growth does not. Its fact sheet calls for spraying in spring when the vines have put out 3 to 5 new leaves: glyphosate at a 2 to 3 percent solution when temperatures are above 55 to 60 degrees, or triclopyr at 2 to 5 percent when the air is no hotter than 85 degrees. Keep the spray off tree trunks, exposed roots and shrubs you want to keep, and expect a second pass on growth missed under layers of vines. The Texas institute adds that cutting stems first makes the chemical work better. The label is the law in every state, and who applies it matters too. In Texas, Occupations Code 1951.003 covers controlling weeds and pests of plantings in a park or next to a residence for pay, including work done as part of a job, and 1951.301 requires a structural pest control business license. In Florida, section 482.156 gives landscape maintenance workers a limited certification for weeds in plant beds, driveways, sidewalks and patios, using only handheld or backpack equipment and products with no signal word or "caution" on the label. In Colorado, C.R.S. 35-10-103(2) defines a commercial applicator as anyone in the business of applying pesticides for hire, and 35-10-106 requires at least $400,000 in liability insurance. Ask for the license number in writing. Our guide on how to hire an HOA landscaping contractor covers the bid.

Who does which part

Volunteers can do the ground-level work: cutting at the base and at eye level, clearing the ring and bagging debris. That suits a work day with gloves, loppers and a sign-in sheet. Our guide on how to run an HOA volunteer work day covers waivers and supervision. Keep volunteers off ladders. Anything above reach, any tree near a power line and any vine thick enough to need a chainsaw goes to an insured arborist. Herbicide goes to a licensed applicator, never to a resident with a pump sprayer from the garage. Vines on an owner's lot are a separate question. Check the CC&Rs before telling owners to clear their own trees.

Wording you can copy

Motion: 'Move that the association hire [company], [state] license number [number], to remove climbing vines from the common-area trees numbered on the attached map by cutting each vine at the base and at eye level, clearing a [3 to 5] foot ring around each trunk, leaving upper vines in place and hauling all cuttings off site, with a follow-up herbicide treatment of regrowth in [month], at a cost not to exceed $[amount].' Newsletter paragraph: 'You may notice dead ivy and vines hanging in some of our common-area trees this year. That is on purpose. Our crew cut the vines at the base so they die in place instead of tearing bark on the way down. They will brown and fall off over time. Please do not pull them down or plant ivy along common fences. If you see a vine climbing a common-area tree, send the location to [email].'

A sample year and the mistakes to avoid

January: walk the property while trees are bare, update the vine map and get bids. February or March: cut and ring every mapped tree, or hold a volunteer day for the ground-level trees. April to May: licensed treatment of regrowth once 3 to 5 new leaves appear. Summer: spot check, pull seedlings in the rings, and in Colorado look for clematis flowers to confirm the patches. Fall: second spot treatment if needed. The mistakes that come up again and again: pulling vines down out of the canopy, cutting at the base only so the vine stays rooted along the trunk, composting ivy on site, letting a volunteer climb a ladder against a vine-covered tree, spraying old ivy leaves in midsummer and calling the herbicide a failure, and stopping after one year because the trunks look clean. Plan on two or three seasons of follow-up before the map stays empty.
