Description : i have a black walnut tree and all the green balls are on the ground, when do i harvest them, and how long do they last
Last Answer : U have 2 layers to go to get to the nut meat. If u crack the green balls when fresh, your hands will be black with stain for about 10 days. U can knock the green hucks off with a hammer or let ... green hulls and bottle to use for sun spots and skin cancers but I don't know if it works or not.
