Defender-Guards provide a cost-effective, eco-conscious way to protect young vines and trees from environmental challenges like wind, sunlight, and herbicides. Made from biodegradable paperboard, these sleeves help create a favorable microclimate and support a smooth transition from the nursery to the field, encouraging strong early growth.
Free from glues and harmful chemicals, Defender Guards are designed to promote sustainable farming practices while keeping soil and crops safe. Made with a milk-carton-style paperboard, they naturally decompose in the field, offering an environmentally friendly alternative to conventional plastic guards.

By acting as a weed barrier, our sleeves can reduce maintenance, pesticide use, and plant mortality—helping trees and vines produce up to a year sooner.
