Bindweed: why it keeps coming back and how to control it
Bindweed is a fast-twining perennial weed with arrow-shaped leaves and white or pink trumpet flowers that smothers plants, fences and walls. Its brittle, deep roots regrow from tiny fragments, which is why it keeps returning. It is not dangerous, but it needs persistent control through digging, exhausting the roots, or careful targeted treatment.
- Also known as
- hedge bindweed, Calystegia sepium, field bindweed, Convolvulus arvensis
- Easily confused with
- morning glory (related, ornamental), black bindweed, field bindweed versus hedge bindweed (different sizes)
- How serious
- Low to moderate: harmless but persistent and smothering
- Typical cost
- DIY control is free aside from weedkiller; contractor clearance is priced by area and difficulty
How to identify bindweed
Bindweed has thin, twining stems that wind anti-clockwise up anything they reach, with arrow or heart-shaped leaves. Hedge bindweed has large white trumpet flowers up to around 5cm; field bindweed is smaller with white or pink-striped flowers.
It appears from late spring, climbing rapidly through borders, hedges and over fences. The key feature for control is the root system: white, brittle, far-reaching underground stems and roots that snap easily and regrow from small pieces. The RHS provides identification and control guidance.
How serious is it?
Low to moderate: harmless but persistent and smothering
Bindweed is not harmful to people, pets or buildings. It is a persistence problem rather than a safety or legal one, and it is not a listed invasive plant in the way knotweed or hogweed are.
The difficulty is that it smothers and competes with garden plants and regrows readily from root fragments left in the soil, so it can dominate a border or hedge if left unchecked. Patience and method, not a single treatment, are what bring it under control.
How to fix it yourself
- For small areas, dig out as much of the white root as you can, working carefully to remove long sections rather than snapping them, since fragments regrow.
- Weaken it by repeatedly removing every shoot as it appears, which gradually starves the roots over a season or more.
- Guide stems up canes away from your plants so you can treat or remove them without harming wanted plants.
- A glyphosate-based weedkiller applied to the leaves, following the label, can control it; training stems up canes first concentrates the treatment on the bindweed.
- Mulch cleared ground and stay vigilant, as bindweed returns from any root left behind and from neighbouring land.
When to call a professional
- Heavy, established infestations across a large garden or coming through from neighbouring land that you cannot keep on top of.
- Situations where you want a managed clearance before replanting or landscaping.
Who to call
- A professional gardener or landscaper for clearance and replanting of a heavily infested area.
- A weed-control contractor for large or boundary-spanning infestations.
Indicative cost: DIY control is free aside from weedkiller; contractor clearance is priced by area and difficulty. Prices vary by area, severity and access, so always get a written quote.
Frequently asked questions
Why does bindweed keep coming back?
Because it regrows from its deep, brittle roots. Any small piece of root left in the soil can sprout a new plant, so digging that snaps the roots, or cutting the top growth alone, leaves it to return. Persistent removal or careful treatment over time is what controls it.
How do I get rid of bindweed permanently?
Combine methods: dig out as much root as you can in long sections, remove every regrowing shoot to starve the roots, and treat foliage with a glyphosate weedkiller per the label, ideally training stems up canes first. Expect it to take more than one season.
Is bindweed harmful?
Not to people, pets or buildings. Bindweed is a persistence problem, not a safety or legal one, and it is not a listed invasive plant like knotweed. Its harm is to other garden plants, which it smothers and competes with if left unchecked.
Can I just pull bindweed up?
Pulling helps but rarely clears it, because the brittle roots snap and regrow from the fragments left behind. Repeatedly removing every shoot weakens it over time, and digging out long root sections or careful weedkiller use gives better long-term control.
