How to Control Lemon Balm: A Comprehensive Guide
Introduction
Lemon balm is a popular herb known for its pleasant, lemony flavor and aroma. It’s easy to grow, but it can quickly become invasive if not properly controlled. This guide will provide comprehensive instructions on how to prevent lemon balm from spreading, control it effectively, and eliminate it from your garden.
Preventing Lemon Balm from Spreading
- Choose a contained growing area: Plant lemon balm in raised beds or containers to limit its spread.
- Shear regularly: Cut back the plant two to three times per year to prevent flowering and seed production.
- Remove flowers promptly: If the plant does bloom, remove the flowers before they go to seed.
Controlling Lemon Balm
- Hand-pulling: If the plant has already gone to seed, pull it out by hand. Be sure to remove the entire root system and any runners (stolons).
- Loosen the soil: Use a garden fork to loosen the soil before pulling, especially if it’s hard.
- Persistence: Controlling lemon balm requires regular attention. Pull out small shoots as soon as they appear.
Eliminating Lemon Balm
- Manual removal: Dig up the entire root system and all stolons. It may require multiple attempts to completely eliminate the plant.
- Chemical control: As a last resort, consider using an herbicide specifically labeled for lemon balm control. Follow the instructions carefully and take precautions to avoid harming other plants.
Additional Tips
- Monitor problem areas: Keep an eye out for areas where lemon balm tends to grow and take prompt action to remove it.
- Mulch around plants: Spread mulch around established plants to suppress weed growth, including lemon balm.
- Avoid using lemon balm as a ground cover: While it can be tempting to use lemon balm as a ground cover, it’s best to avoid this as it can quickly take over.
- Choose sterile varieties: Consider planting sterile varieties of lemon balm that do not produce seeds.
Conclusion
Controlling lemon balm can be challenging, but it’s possible with patience and persistence. By following the steps outlined in this guide, you can effectively prevent lemon balm from spreading, control it effectively, and eliminate it from your garden. Remember to monitor your garden regularly and take prompt action to keep this invasive plant in check.
