I have a hige pile of nursery soil from all the plants that either died or were bare rooted. I sift out the usable bark for use later. I'm a big fan of pine bark. Honestly I don't know if it's pine, spruce, or fir, but it has a lot of usable properties.
OOOHHHH!!!! lol so its just a barrier forcing the trunk/ branches to go another direction besides straight lol Makes perfect sense now. The word striations was throwing me off. I was thinking lines along the sides of the stems, as if struggling to force through. Got it! Thank you!
