I gave up on bamboo,it rots at in ground portions.Then the interior hollow cells harbor crud,and bugs.We went to the fiberglass stakes.We use the propylene pull line for our cherrys.The tomato clips fit nice and don’t slip.Growers here in Homestead are painting those black containers white,and using white reflective on the ground for the inground maters.Amazon has the poles to 5 foot.Good luck.
