Our yard is being overrun by shiny geranium, which was carried in on "compost" a few years ago. We live on a wooded acre, and the low-growing bright green ground cover is beautiful, but we were notified that we must attempt to eradicate it, or face stiff fines.
We garden organically, and have well water... What is the safest herbicide for this purpose? What is the most effective?
glyphosate (roundup) is pretty safe. However you may need to be careful with root to root transfer with desirable species.
A 2-4D banvil mix such as weed master may also be effective
