Will Grass Out Max kill grass without harming my moss lawn?

I am cultivating a moss lawn at my mountain cabin using multiple verities of local moss transplanted from the surrounding woods. I have an infestation of wild grasses that I need to get rid of. Is this product safe to use on my moss lawn to kill the grasses? Should I use a surfactant ?

Answer:

Grass Out Max (Clethodim Herbicide) would injure the moss. We would recommend using Ferti-lome Over the Top II Weed Killer to kill grassy weeds in and around moss. The product label lists different varieties of moss that are tolerant, please view the product label HERE.
