This durable, natural weed barrier is 100% plant-based and does not need to be removed from the soil after use and will NOT girdle or strangle your trees like plastic weed barriers. Naturally reflective materials reduce extreme heat stress and increase tree photosynthesis and growth. Squares are convenient for individual trees and have a pre-cut opening in the middle to make planting easy. Visit https://www.rootthrugarden.com/max for more information.
