Management:

While Viper's Bugloss has some ecological value as a pollinator-attracting plant, it can become invasive in certain areas. Management strategies include:

  1. Mechanical Control:

    • Regular mowing or cutting before seed set can help prevent further spread.
    • Hand pulling or digging out small infestations, wearing protective gloves due to the stiff hairs.

  2. Chemical Control:

    • Herbicides targeting broadleaf weeds may be used, following recommended guidelines. Consult with local agricultural extension services for appropriate herbicides and application rates.

  3. Prevention:

    • Monitoring and early intervention are crucial to prevent the establishment and spread of Viper's Bugloss.
    • Implementing good land management practices to reduce disturbances that favor its growth.
