Growing Peppermint Jun 8, 2020 15:13:20 GMT -5 Quote Select PostDeselect PostLink to PostBack to Top Post by girl90048 on Jun 8, 2020 15:13:20 GMT -5 Has anyone tried growing peppermint? Wondering how long it takes for it to sprout. I put 4 seeds in a pod in my AG on May 24th. So far, nothing. All the other seeds I've started in my AG have sprouted within a week, except for spinach.
