Weed of the Month – COMMON BURDOCK (Wild Rhubarb)

If there is one weed that seems to appear in some of the strangest places (along with poison ivy) is common burdock, also known as wild rhubarb.

We see this big and bold, large-leaved biennial weed growing within deciduous hedge rows, along edges of lawns, sides of buildings and even under large evergreen trees.   Anywhere the plant can avoid routine mowing or soil cultivation, but still receive modest sunlight exposure, the plant will flourish.

Common Burdock (also known as wild rhubarb):  Burdock is a biennial plant (2 year life cycle) that reproduces by seed.  Plant produces spiny cockleburs (seed heads) which cling to clothing, shoe laces and even animal fur for easy relocation.  Plant has a large fleshy taproot and massive dark green colored leaves with a hairy textured leaf underside.

Remove common burdock by digging out plant when small or by applying a systemic herbicide directly to actively growing foliage (surrounding environment dependent) for best long term results.

Boo……. THISTLE …….. Boo ……….. GO AWAY ALREADY!!!

Anyone that has had a run-in with thistle around their yard knows how tough this broadleaf weed is and how difficult it is to completely eradicate.  With it’s deep and wide spreading root mass and sharp pointed prickly foliage, it will not pull out of the ground easily (or completely) without a fight.  Pacocha - Thistle Foliage Close UpThe only effective and proven way we have found to completely kill mature thistle (in particular) is by applying a selective or non-selective (site dependent) systemic herbicide directly to it’s foliage.  Often times several spot herbicide applications are needed over the course of many growing seasons (3 to 5 years) to completely kill thistle found growing in a regularly maintained lawn (in particular).Pacocha - Large Thistle Found Growing in Bed Along Walkway

Tips on controlling and keeping thistle out of your lawn and landscape.

  • Thistle can have a biennial or perennial life cycle (specific thistle variety dependent)
  • Never plant a new lawn or create new gardens without first completely eliminating any/all resilient thistle plants first.
  • When applying a systemic herbicide, allow plenty of time (4-8 weeks) for the liquid herbicide (selective or non-selective – site dependent) to translocate through the entire plant (from foliage to root mass) thus ensuring a complete kill.
  • It is much easier to chemically eradicate thistle when therePacocha - Thistle Growing in Lawn are no other desirable plants (manicured turf grass, ground cover, vegetables, etc.) located in close proximity to the unwanted weed.
  • Always eradicate thistle found in lawn areas AND adjacent plant bed spaces.  Since thistle spreads by seed, rhizome and/or cut root segments (variety of thistle dependent) it will continue to spread anywhere it can unless totally eliminated.
  • Thistle seed can remain viable in the soil for up to 20 years!!
  • If you have a bird feeder in your yard, try to avoid using bird feed that includes thistle seed.
  • Continue to monitor your property for young thistle plants and try to manually remove them whenever possible.  If manual removal is no longer a feasible option, spot treat them with a systemic selective (lawn areas) or non-selective (areas where no other desirable vegetation is located) herbicide before the plant is allowed to flower and set seed.Pacocha - Multiple Thistle Growing in Lawn
