Other Names: Cirsium spp., Carduus spp.

Type: Broadleaf Perennial

Appearance: Thistle plants are characterized by their spiny leaves and distinctive globe-shaped flower heads. There are various species of thistle, each with its unique appearance, but most share common traits of spiky leaves and vibrant purple or pink flowers.

Risk: Thistle can establish itself in lawns, gardens, and natural areas, forming dense colonies. Its deep taproot makes it resilient, and its ability to produce numerous seeds contributes to its spread.

Timing: Thistle becomes most noticeable in the late spring and early summer when it produces its characteristic flower heads.

Outlook: Due to its deep-rooted nature and prolific seed production, thistle can be challenging to control. Effective management measures are crucial to prevent its dominance.

How to Control Thistle

Managing this weed effectively requires a combination of preventative measures and quick treatment.


Take action before this weed appears on your lawn by following best lawn care practices, especially focusing on:

  • Early Detection: Actively monitor your lawn and garden for signs of thistle and address it promptly.
  • Regular Mowing: Regular mowing prevents thistle from reaching maturity and producing seeds.


If you find this weed on your lawn, it’s best to take action immediately. Working with a lawn care professional is most effective, but you can also try these DIY options:

  • Selective Herbicides: Apply selective herbicides labeled for broadleaf weed control, targeting thistle while preserving the health of the surrounding plants.
  • Mechanical Removal: In small infested areas, carefully hand-remove thistle, ensuring complete removal of the taproot.
