Corrugated Plastic Tree Guards are the ventilated sleeves that clip around the trunk of a newly planted sapling, shielding it through the first couple of years when the bark is thin and everything wants to take a bite out of it. They stop a strimmer line from chewing a ring around the base, a rabbit or vole from girdling the stem overnight, and the worst of winter sunscald on the south-facing bark.
Cut from twin-wall polypropylene sheet, Plastic Tree Guards are lighter than the old wire-mesh or solid PVC tube, yet stiff enough to stand up to a lawn tractor nudging past. The ribbed profile lets air circulate around the bark instead of trapping damp against it, which is why a corrugated PP outlasts a solid plastic sleeve—solid ones trap moisture and invite rot where the bark meets the soil.
Diameter is cut to order from 10 cm for nursery stock up to 30 cm for bigger transplants, and height typically runs 40 cm to 90 cm depending on the local rabbit or deer browsing line. Plastic Tree Guards are most often spec'd in a hinged C-clip or split-pipe design that opens around the trunk without threading it over the crown, plus a small stake or zip tie to hold it upright in wind. Colors run black or green to blend into the landscape, with white and custom shades for visibility on medians and roundabouts.
