So everything I read about told me no. This is not usually how lemon balm reproduces but my son waters plants like a waterfall.
My lemon balm got stuck under the dirt and grew out of it. I found out when I pulled it up that roots had sprouted.
I was happily surprised and now I have two more babies. My first clones, but I spoke to the guy at Yard by Yard and he said I am supposed to be calling it propagation. Words aren’t important check out my babies.
