Q: I thought this was henbit but the leaves are furry purple/magenta besides being green. Do you know what this sort of invasive plant is?
A: No question here…it’s henbit! This broadleafed weed sprouts in October and becomes rampant in early spring. The purple flowers give it away.
The best treatment in winter and spring is to dig it or spot-spray with a broadleaf weedkiller herbicide like Weed B Gon.
You could also apply imazaquin (Image for Nutgrass).
Next September, apply a broadleaf weed preventer like Portrait or Amaze.
