Agapanthus, also known as the Lily of the Nile, has garnered some negative attention lately. Even though this is a pleasant and visually appealing plant, it is an aggressive plant and seeds often in unwanted places. It is relatively simple to stop the unwanted seeding by cutting the stems that produce the light seeds often. To get rid of this lily altogether, a simple herbicide will do the trick. Remember, if the roots have moved toward other plants and have intertwined with other root systems, it may be necessary to remove or kill the other plants as well to fully remove and kill agapanthus.
Things You'll Need
- Hedge clippers
- Burning facility
Clip back the Agapanthus as much as possible.
Dig around the base and pull out as much as possible of the root system.
Place all plant parts into the wheelbarrow.
Sprinkle or spray herbicide in the area where the agapanthus used to be.
Till into the soil.
Burn the plants.
Tips & Warnings
- Repeat with herbicide as necessary. Remove all plants that the agapanthus has become involved in. It may be necessary to clear all around the agapanthus and replant if the agapanthus has become seriously aggressive.
- Use caution around fire and with herbicides. Be sure to follow all label instructions on chemicals. Failure to exercise caution can result in serious injury.
