Bee Balm Control
Bee balm, known for its vibrant blooms and ability to attract pollinators like bees, butterflies, and hummingbirds, is a popular addition to many gardens. However, as beautiful as this perennial plant is, many gardeners wonder, “Is bee balm invasive?” Understanding the growth habits of bee balm is essential for anyone looking to cultivate it responsibly.
Bee balm is a beautiful and beneficial plant, but it can also be vigorous and spread aggressively. If you find that it’s becoming too invasive or you want to control its growth, here are some strategies:
Physical Methods
- Dividing: Regularly dividing bee balm plants can help manage their size and prevent them from spreading uncontrollably. Divide the plants every 2-3 years.
- Discarding Shoots: Regularly remove any unwanted shoots or suckers that appear around the base of the plant. This will help prevent the plant from spreading through underground runners.
- Controlling Root System: If bee balm is becoming too invasive, you may need to dig up and remove portions of its root system. This can be labor-intensive but is often effective.
Cultural Practices
- Improve Airflow: Ensure that bee balm plants have adequate airflow to help prevent diseases like powdery mildew, which can weaken the plants and make them more susceptible to spreading.
- Choose Dwarf Varieties: Consider planting dwarf varieties of bee balm, which tend to be less invasive.
Chemical Control
- Fungicide: If powdery mildew is a significant problem, you may need to apply a fungicide. Choose a fungicide that is specifically formulated for powdery mildew control.
- Natural Powdery Mildew Treatment: For a more natural approach, try treating powdery mildew with a homemade mixture of baking soda, liquid soap, and water.
Important Considerations:
- Propagation: If you want to control the growth of bee balm but still enjoy its benefits, consider propagating it through cuttings or division and planting the new plants in containers or a separate area of your garden.
- Benefits: While bee balm can be invasive, it also offers many benefits, such as attracting pollinators and providing medicinal properties. Before taking drastic measures to control its growth, carefully consider the pros and cons.
Bee Balm Varieties
Bee balm, a member of the mint family (Lamiaceae), is a popular garden choice due to its vibrant blooms, pleasant fragrance, and ability to attract pollinators. There are several varieties of bee balm, each with its unique characteristics.

Growing Bee Balm
Bee balm is a popular garden choice due to its vibrant blooms, pleasant fragrance, and ability to attract pollinators. If you’re interested in growing bee balm, here’s a guide to get you started:
Planting Bee Balm
- Choose a Location: Bee balm prefers full sun to partial shade and consistently moist soil. It is a perennial plant that is hardy in zones 3-9.
- Prepare the Soil: Amend the soil with compost or well-rotted manure to improve drainage and fertility.
- Plant the Bee Balm: Space the plants 12-18 inches apart to allow for adequate air circulation.
Caring for Bee Balm
- Watering: Water the plants regularly, especially during dry periods. Aim to keep the soil consistently moist but not soggy.
- Fertilizing: Fertilize the plants in early spring with a balanced fertilizer.
- Deadheading: Deadhead the spent blooms to encourage continuous flowering.
- Dividing: Divide the plants every 2-3 years to maintain vigor and prevent overcrowding.
- Protecting from Pests and Diseases: Bee balm is susceptible to powdery mildew and can attract aphids. Monitor the plants regularly and take action if you notice any signs of problems.
Maintenance Tips
- Mulching: Mulch around the plants to help retain moisture and suppress weeds.
- Pruning: Prune the plants in late fall or early spring to shape them and remove dead or damaged growth.
- Dwarf Varieties: Consider growing dwarf varieties of bee balm if you have limited space.
Additional Considerations:
- Bee and Wasp Stings: Bee balm attracts bees and wasps, so be cautious when handling the plants. Wear gloves and long sleeves to protect yourself from stings.
- Insect Bites: Bee balm can also attract mosquitoes and other biting insects. Use insect repellent or avoid the garden during peak mosquito activity.
- Neglect: Bee balm is a relatively low-maintenance plant that will benefit from regular care and attention. Neglect can lead to reduced flowering, disease problems, and a decline in overall health.
