Trumpet vine (Campsisradicans), also known as trumpet creeper, is a fast-growing perennial vine that produces beautiful, trumpet-shaped flowers. While it can be a beautiful addition to your garden, it can also become invasive and difficult to control. If you’ve found that your trumpet vine has become a nuisance, it’s time to take action. Here are four ways to effectively kill trumpet vine and prevent it from overtaking your garden.

1. Manual Removal

The most straightforward method to kill trumpet vine is through manual removal. This process involves physically digging up the root system and cutting back any remaining vines. To do this:

– Locate the main root of the trumpet vine and, using a spade or shovel, dig around it to loosen the soil.

– Carefully pull out the main root and as much of the root system as possible.

– Cut back any remaining vines to ground level.

– Regularly monitor the area for any new growth and remove it promptly.

Note that manual removal can be labor-intensive and may not eradicate the entire root system, so diligent monitoring is necessary.

2. Smothering Method

Smothering is an effective technique for killing trumpet vine without using harmful chemicals. To smother your trumpet vine:

– Mow or trim the vine down as close to ground level as possible.

– Cover the area with multiple layers of newspaper or cardboard.

– Place a layer of mulch or compost on top of the layers of newspaper/cardboard.

– Make sure to maintain this setup for several months in order to suffocate the vine completely.

3. Chemical Control

For larger infestations or stubborn trumpet vines, chemical control may be necessary. Ensure that you follow all manufacturer’s directions and warnings when working with herbicides:

– Cut back the trumpet vine, leaving only a small stump.

– Apply an appropriately labeled glyphosate-based herbicide directly to the stump, following the manufacturer’s instructions.

– Monitor the treated area for any new growth, reapplying herbicide as necessary.

4. Biological Solutions

If you’re hoping to avoid manual labor or chemicals, consider introducing natural trumpet vine predators to help control its growth. Some animals and insects are known to feed on trumpet vine, such as deer, goats, rabbits, and certain types of caterpillars.

Remember that invasive plants like trumpet vine can harm native ecosystems and take over your garden if left unchecked. Whichever method you choose to eliminate your trumpet vine problem, persistence and timely intervention will be crucial to successfully kill the plant and keep your outdoor space looking beautiful.
