Is Lavender classified as a dicot or a monocot? I am asking as my understanding is that 2,4-D would have no effect on a monocot therefore allowing me to spray 2,4-D on the lavender essentially killing all the dandelions that pop up and require a massive amount of hand weeding. I guess then the ultimate question would be is 2,4-D safe on lavender?
Lavender is a dicot plant. Do not treat with 2,4-D or other broadleaf herbicides. It will be severely injured or killed.
