ArborGard® wraps easily around the trunks of young trees to protect them from damaging string trimmers, These soft and supple protectors won't damage your tree and will also help to protect the bark from damaging gardening equipment, tools, rodents and other small pests. Holes are sized to prevent insect infestation and bark rot. ArborGard® is manufactured in a round tube form and unlike flat tree guards, will not lose its coil shape in the hot sun. One 9" tall ArborGard® fits trees with up to a 3" truck. Two or more can be combined for trees larger than 3". Sold each or in cases of 100.
