How to Safely Remove and Kill Trumpet Vine: A Comprehensive Guide

Trumpet vine, also known as Campsis radicans, is a hardy and fast-growing plant that produces beautiful orange-red trumpet-shaped flowers. However, this invasive species can quickly take over your garden or yard, choking out other plants and damaging structures with its aggressive growth. If you're struggling with a trumpet vine infestation, don't worry! In this article, we'll provide you with a comprehensive guide on how to safely remove and kill trumpet vine without causing harm to yourself or the environment.

Identifying Trumpet Vine

The first step in removing and killing trumpet vine is identifying it. Trumpet vine has large, toothed, oval-shaped leaves that grow alternately along the vine. Its showy trumpet-shaped flowers bloom from mid-summer to early fall and are typically bright orange-red in color. The vine itself is woody and can grow up to 30 feet long, attaching itself to trees, fences, and buildings with aerial rootlets.

If you're not sure if you have trumpet vine or another plant, look for these distinctive features. You can also consult a local gardening center or horticulturist for help with identification.

Removing Trumpet Vine by Hand

If you only have a small trumpet vine infestation, you may be able to remove it by hand. This is the safest and most environmentally friendly method of removal, as it avoids the use of chemicals. Here's how to do it:

1. Put on a pair of thick gloves and long sleeves to protect your skin from the sharp aerial rootlets.
2. Cut the trumpet vine stem near the ground using pruning shears or a saw. Be careful not to damage any surrounding plants or structures.
3. Remove the remaining root system by digging around the area with a shovel or garden fork. Be sure to remove all the roots, as even a small piece left behind can regrow into a new plant.
4. Dispose of the plant and roots in a trash bag or compost bin. Do not dispose of trumpet vine by composting unless you are sure that you have removed all the roots, as they can regrow and spread.

Killing Trumpet Vine with Chemicals

If you have a larger trumpet vine infestation or prefer not to remove it by hand, you can use herbicides to kill the plant. However, be aware that herbicides can be harmful to the environment and should be used with caution. Follow these steps to use herbicides safely and effectively:

1. Choose an herbicide labeled for use on trumpet vine. Look for one containing glyphosate, triclopyr, or imazapyr.
2. Put on protective clothing, including gloves, long sleeves, and goggles, to avoid contact with the herbicide.
3. Apply the herbicide to the trumpet vine foliage using a sprayer, being careful not to spray any surrounding plants or structures.
4. Wait for the herbicide to take effect. This can take several weeks to a month, depending on the type of herbicide and the size of the plant.
5. Once the trumpet vine has died, cut it down and dispose of it in a trash bag or compost bin. Do not dispose of it in your regular garden waste, as some herbicides can persist in the environment.

Preventing Trumpet Vine from Regrowing

After removing or killing trumpet vine, it's important to prevent it from regrowing. Here are some tips on how to do it:

• Monitor the area regularly for regrowth. Even a small piece of root left behind can regrow into a new plant.
• Apply mulch to the area to suppress weed growth and discourage regrowth.
• Consider planting a ground cover or creating a border around the area to prevent trumpet vine from spreading.
• If you're replanting the area, choose plants that are native to your region and not invasive.
