Greetings fellow gardeners/landscapers! I urge all throughout the US & Canada to google "garlic mustard" to learn about this invasive scurge, & the damage it is doing to native flora & fauna. At my place here in Revoltistan (currently in hostile occupation of SE Michigan), this pungent weed is one of the first to emerge when the snow clears. It out-competes the native plants, reducing food for bugs, birds & other critters. It has the potential to greatly reduce both plant & animal diversity, & it is taking over with alarming speed.
Research is being done to find a natural enemy of garlic mustard, & some foes have been found, but they want to test some more before implementing a solution. Until then, there are some steps you can take to kill it, but I'll leave that to the websites devoted to the topic. My approach is to use a 1% glyphosphate solution on the rosettes just after the snow melts, which kills the garlic mustard, but leaves the other dormant desirable plants safe. Then throughout the year, I'll use a stronger solution on survivors, or cut'm off at the ground. Caution! Cut/pulled plants should be burned instead of composted, since the seeds can last up to 10 years.
One last tip: For fans of The Simpsons Treehouse of Horror series, it helps to chant "Die! Die! Everybody die!" while you work.
