How to Kill a Ginger Plant

by Marylee Gowans

Wild ginger (Hedychium gardnerianum) -- also known as kahili ginger and yellow ginger lily -- is an evergreen perennial growing in U.S. Department of Agriculture plant hardiness zones 9b through 13. This attractive plant produces lemony yellow blooms that fill the air with a pleasant aroma. Unfortunately, wild ginger spreads quickly and can block sunlight from desirable plants, essentially suffocating them. Thankfully, you can kill ginger plants with both manual and chemical control methods.

1. Hand Pulling

1 Wear heavy work gloves to protect your hands while removing the ginger plants. Hand pulling works best at controlling small infestations such as those found in gardens and flowerbeds.

2. Hand Pulling

2 Grab small seedlings at the base of the stem near ground level. Pull the plants and roots out of the ground.

3. Hand Pulling

3 Dispose of the removed seedlings in a garbage bag immediately. Avoid composting the plants or leaving them on the ground as this could result in future infestations.

4. Hand Pulling

4 Monitor the location for future growth removing new seedlings as they emerge.

5. Chemical Removal

1 Wait until a calm day in spring through late autumn. Wear chemical-resistant rubber gloves, long-sleeve shirt, pants, socks, work boots and safety glasses.

6. Chemical Removal

2 Mix 12.5 gallons of water with 1/4 tablespoon of an herbicide containing Metsulfuron methyl as the active ingredient.

7. Chemical Removal

3 Pour the diluted Metsulfuron methyl herbicide into a handheld sprayer. Spray the leaves of the ginger plant thoroughly, but not excessively to the point the herbicide is dripping off the plant.

8. Chemical Removal

4 Allow the plant to brown and dry before removing, mowing or cutting it down. This may take several months, according to the Global Invasive Species Database.
