Did something new pop up in your garden? Did you hope it was a volunteer? Keep a close eye on your garden for noxious weeds. Invasive, aggressively-spread weeds can take over after very little time.
Some of the worst Colorado noxious weeds are: leafy spurge, spotted knapweed, diffuse knapweed, Russian knapweed, Canada thistle, musk thistle, Dalmatian toadflax, yellow toadflax, field bindweed and purple loosestrife.
