How to Deal With Bindweed in UK Gardens

Why Bindweed Is So Persistent

Bindweed (Calystegia sepium, hedge bindweed, and Convolvulus arvensis, field bindweed) is one of the most persistent weeds in UK gardens. It twines through other plants, smothering them, and regrows from any fragment of root left in the soil. The roots can go 3 metres deep and 5 metres sideways, making total removal almost impossible in one go.

In the Chilterns, bindweed is particularly common in established gardens with hedges and shrubs. The fertile soils and the partial shade of hedges provide ideal conditions. A garden that has been neglected for a season can have bindweed threaded through every shrub and perennial.

The good news is that bindweed can be controlled with persistence. It takes 2 to 3 years of consistent effort, but it is possible to get on top of it. This guide explains the methods we use in client gardens across Oxfordshire, Buckinghamshire, Berkshire and Bedfordshire.

How to Identify Bindweed

Bindweed is easy to identify once you know what to look for:

• Leaves: arrow-shaped, bright green, 5 to 10cm long
• Stems: thin, twining, can grow 2 to 3 metres in a season
• Flowers: white or pink trumpet flowers, June to September
• Roots: white, fleshy, can go 3 metres deep

Bindweed is often confused with morning glory (Ipomoea), but morning glory is an annual with larger flowers, while bindweed is a perennial with smaller flowers.

Methods for Controlling Bindweed

Method 1: Dig Out the Roots

The most effective organic method. Dig out as much of the root system as you can, then dig out any regrowth as soon as it appears.

1. Dig carefully around the bindweed, following the white roots.
2. Remove every bit of root you can find. Even a 2cm fragment will regrow.
3. Use a sieve to remove small root fragments from the soil.
4. Do not compost the roots. Burn them or put them in the bin.
5. Check weekly for regrowth and dig out any new shoots.

This method takes 2 to 3 years of consistent digging. Each year, the regrowth is weaker as the root system is exhausted.

Method 2: Smother with Cardboard and Mulch

Block out the light to weaken the plant. This works best for large areas.

1. Cut the bindweed to ground level.
2. Lay thick cardboard over the area, overlapping by 30cm.
3. Cover with a 10cm layer of bark or compost mulch.
4. Leave for 12 to 18 months.
5. Check the edges for regrowth escaping.

This method takes 1 to 2 years, but it is less work than digging and improves the soil at the same time.

Method 3: Glyphosate Treatment

The most effective chemical method. Glyphosate is a systemic weedkiller that travels through the plant to the roots.

1. Wait until June or July, when the bindweed is in full leaf and sending energy to the roots.
2. Untangle the bindweed from desirable plants and lay it on bare soil.
3. Spray with glyphosate at the recommended rate.
4. Leave for 3 to 4 weeks for the glyphosate to work.
5. Dig out the dead roots.
6. Repeat in September if necessary.

Warning: glyphosate will kill any plant it touches. Do not spray on windy days, and protect desirable plants with plastic sheeting.

Method 4: The "Glove Method"

For bindweed growing through desirable plants, where spraying is not possible.

1. Put on a rubber glove, then a cotton glove over the top.
2. Dip the cotton glove in glyphosate solution.
3. Wipe the bindweed leaves with the glove, coating them with glyphosate.
4. Avoid touching desirable plants.
5. Leave for 3 to 4 weeks.

This is slow but effective, and avoids spray drift.

The 3-Year Bindweed Control Plan

Whatever method you choose, plan for 3 years of control. Bindweed cannot be eradicated in one season.

How to Prevent Bindweed Returning

• Dig out roots completely when you find bindweed. Do not let it establish.
• Mulch thickly to suppress seed germination.
• Avoid importing soil that may contain bindweed roots.
• Check new plants for bindweed roots before planting.
• Monitor edges of the garden where bindweed may spread from neighbouring land.

Common Mistakes

• Composting bindweed roots. Compost heaps do not kill bindweed roots. Burn them or put them in the bin.
• Leaving root fragments in the soil. Even a 2cm fragment will regrow. Sieve the soil to remove fragments.
• Expecting one treatment to work. Bindweed takes 2 to 3 years to control. Be persistent.
• Spraying glyphosate in spring. Glyphosate works best in summer when the plant is sending energy to the roots.
• Pulling bindweed instead of digging it. Pulling breaks the roots, leaving fragments that regrow. Dig gently.

Frequently Asked Questions

Can I compost bindweed?

No. Compost heaps do not get hot enough to kill bindweed roots. Burn them, put them in the bin, or drown them in water for 6 weeks first.

Will glyphosate kill my other plants?

Glyphosate will kill any plant it touches. Use the "glove method" for bindweed growing through desirable plants, and protect nearby plants with plastic sheeting.

How long does it take to get rid of bindweed?

2 to 3 years of consistent effort. You can reduce it by 80 percent in the first year, but total eradication takes longer because of the deep root system.
