A plastic net tree guard is a protective barrier designed to shield young trees from various external threats while promoting healthy growth. It typically consists of a lightweight plastic netting material that is wrapped around the tree trunk, forming a cylindrical or conical enclosure.

The primary purpose of a plastic net tree guard is to provide protection against browsing animals, mechanical damage, herbicides, and adverse weather conditions. By creating a physical barrier around the tree trunk, the guard helps to prevent damage to the bark and vascular tissues, which are essential for the tree's health and growth.
