Sometimes we overthink it. Last year my plants had 2-3 seeds when I processed it. Didn’t think anything of it. This spring I dug a ditch for electric to my greenhouse and a waterline. Pure rock and clay. After that was done I was spraying weed killer and found this girl. This is my girl who came up in the worst clay/rock imaginable from a seed dropped last year. When I sprayed it with weed killer before I recognized it as cannibus. Immediately sprayed it off with water, but it killed the top of the plant but it reveged around the top. All I’ve done is water it and a bit of worm castings around it. Then two weeks ago a storm came through and split the base into 3 sections. I taped it back together and it’s doing great. First pic is after I found it, second and third is current. Such an amazing gift.
