Amur Honeysuckle: Identification and Removal
If you've walked a wooded trail anywhere in Central Ohio in April, you've seen it: a green haze in the understory weeks before anything native has leafed out. That's almost always bush honeysuckle, and it's the single most common invasive shrub we run into from the Olentangy corridor down through the Scioto floodplain.
"Bush honeysuckle" usually means Amur honeysuckle (Lonicera maackii), though Morrow's and Tatarian honeysuckle and their hybrids show up too. In the field, treating them as one problem is fine, identification, impact, and removal are nearly identical across all of them.
How to identify it
A few features make bush honeysuckle easy to pick out, even from a moving car in spring:
- Early leaf-out. It's usually the first shrub to green up, often two to four weeks ahead of native species, and one of the last to drop leaves in fall.
- Opposite leaves. Leaves grow in pairs directly across from each other on the stem, oval with a pointed tip.
- Hollow, tan stems. Cut a mature stem and the pith inside is hollow or brown, unlike the solid white pith of native shrubs like arrowwood viburnum.
- Red-orange berries. Small paired berries form in the leaf axils by late summer and persist into winter, which is a big part of how birds spread it.
- Fragrant tubular flowers in May, white to pale pink, fading yellowish with age.
Why is Amur honeysuckle bad for Central Ohio woods?
It's not just that honeysuckle is non-native, it's that it changes how a whole woodlot functions. That early leaf-out and late leaf drop give it several extra weeks of sunlight every year that native spring ephemerals like trillium, trout lily, and bloodroot depend on to complete their life cycle before the canopy closes. Where honeysuckle forms a dense understory, that spring wildflower layer often thins out or disappears.
Its shade and root competition also suppress tree seedlings, which over time can mean fewer young oaks and other native trees replacing the canopy. Some studies have linked dense honeysuckle thickets to higher nest predation for songbirds, since the shrub's open branching structure makes nests easier for predators to find compared to native shrubs. And because a single mature shrub can produce a large volume of bird-dispersed berries each fall, one uncontrolled patch along a fencerow or floodplain can seed a much wider area within a few years.
It thrives here in particular because Central Ohio's mix of disturbed edge habitat, floodplain corridors, and mature but fragmented woodlots gives it exactly the light and soil conditions it wants. You'll find it along the Olentangy, in Scioto River bottomland, in old fencerows across Delaware and Union counties, and in nearly every second-growth woodlot from Franklin County out to the rural edges of the watershed.
How do I get rid of bush honeysuckle?
The right method depends mostly on stem size.
Seedlings and small stems
Anything under about half an inch in diameter can usually be hand-pulled, especially after rain when soil is loose. Get the root crown out, not just the top growth, honeysuckle resprouts readily from a cut or broken stem if roots are left behind.
Cut-and-treat for larger shrubs
For anything too thick to pull, cut the stem low and close to the ground, then treat the fresh-cut stump with an herbicide labeled for woody stem application. This has to happen within minutes of cutting, before the cut surface seals over. It's the standard approach used by most volunteer stewardship crews because it's far more effective than cutting alone, honeysuckle stumps left untreated will send up a thicket of new shoots the following season.
Herbicide-free options
If you'd rather avoid herbicide, repeated cutting works, but it takes persistence. Cutting a stump back two or three times a season, for two or more consecutive years, will eventually exhaust the root system on most plants. Girdling large stems and leaving them standing is another option on sites where you don't need it removed immediately. Whatever method you choose, follow-up visits the next couple of growing seasons matter more than the initial cut.
When is the best time to cut honeysuckle?
Late fall through winter, after a hard frost, is the window most volunteer groups in this region favor. Because honeysuckle holds its leaves so much longer than native shrubs, a frosty November or December woodlot makes it stand out clearly, every other shrub is bare, and the honeysuckle is still green. That makes it far easier to find every stem in a patch, including the smaller ones hiding under larger shrubs, and cutting during dormancy also reduces the amount of stored energy the plant can put toward resprouting. Our seasonal removal calendar lays out the timing for honeysuckle alongside the watershed's other major invasives.
| Method | Best timing | Realistic outcome |
|---|---|---|
| Hand-pulling seedlings | Spring, after rain, when soil is soft | Full removal if the root crown comes out; quick for scattered young plants |
| Cut-and-treat (larger stems) | Fall through winter, after frost | High success rate; stump treated promptly rarely resprouts |
| Repeated cutting, no herbicide | Multiple times per growing season, 2+ years | Gradual decline; requires ongoing follow-up visits |
| Girdling standing stems | Late spring to summer | Slow dieback over a season or two; shrub stays standing |
What can I plant instead of honeysuckle?
Once honeysuckle is cleared, bare soil rarely stays bare for long, new honeysuckle seedlings from the surrounding seed bank, or other invasives like Callery pear, will move in if nothing is planted to compete. Good native shrub replacements for Central Ohio yards and woodland edges include spicebush, arrowwood viburnum, ninebark, and gray dogwood, all of which support far more native insect and bird life than honeysuckle ever will. Our native alternatives guide has a longer list matched to sun, soil, and site conditions.
Frequently Asked Questions
How do I get rid of bush honeysuckle?
Pull small seedlings by hand, root and all. For larger shrubs, cut the stem near the ground and treat the stump immediately with an herbicide labeled for woody stems, or commit to repeated cutting over a couple of seasons if you want to avoid herbicide entirely.
When is the best time to cut honeysuckle?
Late fall into winter, after the first hard frost, when honeysuckle is still green and every other native shrub has dropped its leaves. That makes plants easy to spot, and cutting during dormancy limits resprouting.
Why is Amur honeysuckle bad?
It leafs out weeks before native plants and holds leaves late into fall, shading out the spring wildflowers and tree seedlings that depend on that early-season light. Dense thickets also offer poor nesting cover compared to native shrubs, and one shrub's berry crop can seed a wide area by way of birds.
What can I plant instead of honeysuckle?
Spicebush, arrowwood viburnum, ninebark, and gray dogwood are solid native replacements for Central Ohio sites, offering similar screening and berries while supporting native wildlife. See our native alternatives guide for options by site condition.
The takeaway
Bush honeysuckle isn't going away on its own, but it is one of the more manageable invasives to tackle at the yard or neighborhood scale. Pull what you can in spring, mark the bigger stems for a fall cut-and-treat session, and replace what you remove with something native. Multiply that across enough properties in the watershed and the difference in spring wildflower cover shows up within a few years.
