I’m trying to kill stinging nettles and there are ferns mixed in some places and I would rather not kill the ferns.
The product label for the Fertilome Weed-Out Lawn Weed Killer with Trimec indicates that you should not apply it on or near desirable ornamental plants. So this would not be safe to spray on your ferns or in a way where overspray could get onto them.
