Interesting Facts About Weeds

We all talk about the weeds in our ground cover but how about some interesting about them? Did you know that scientists have discovered that earthworms contribute to the spread of giant ragweed by systematically collecting and burying its seeds in their burrows?

How about cows that graze on garlic mustard (Alliaria petiolata) or other mustard weeds produce milk with a garlic flavor? Similarly, wild garlic (Allium vineale) can “flavor” wheat crops and reduce their market value. It’s NOT the best way to make garlic bread!

Scotch thistle (Onopordum acanthium) is said to have helped win a battle. Norsemen came ashore planning to surprise sleeping Scottish forces and removed their boots for a quieter assault. A prickly patch of thistle growing between the two armies is said to have saved the day and became the Scottish National Flower.

After a walk, Swiss engineer George de Mestral observed burs from common burdock (Arctium minus) stuck to his wool pants and his dog’s fur. A few years later he patented Velcro, an invention inspired by the weed.

Ancient Egyptians wrapped their dead in the leaves of the giant reed (Arundo donax), now one of the worst riparian weeds in the U.S.

If you decide herbicides are necessary to manage dandelions and other broadleaf weeds that germinate in the fall, you’ll have the best control if you apply them in fall. The period from late September to mid-November is ideal because broadleaf weeds are most susceptible to herbicides at this time. Read and follow all directions on the herbicide label. Apply on a sunny day with moderate temperatures, no wind, ample soil moisture and no rain in the 24-hour forecast. Herbicides containing two or more active ingredients including 2,4-D, MCPP, MCPA, dicamba, or triclopyr will control most broadleaf weeds with one application. Consider spot-spraying the weeds to limit the amount of pesticide you apply. Many “weed and feed” products should be applied in mid- to late-September to receive the full benefit of the fertilizer and the most efficacious weed control.

No, we really don’t get milk from milkweed.
