Tree shelter tubes (Fairfield & Nippersink Rds)

These 12 (or more) tubes are used to help young or freshly planted trees to grow and also protest them from pests and sunscald. They are biodegradeable and corrugated to help hold moisture. They have zip tie fasteners to attach to supporting sticks or posts for stability. You may have seen these in forest preserves. Good info here: https://tinyurl.com/yz9w49cr
