That's actually a coco fiber Lindsey. I cut it in half, formed a cone (like ice cream cone) and glued the sides dry. Once dry I filled it up with my Catts and orchid bark and tied it around the oak tree. My hope is that, overtime, the roots will grow around the coco fiber and attach itself to the oak tree so there is no more need for the ties. I'm already seeing roots around the coco fiber and on the oak tree.
Oh I did left a few holes on the cut sem so that the roots will be able to escape and attach to the oak tree.
