These are made of a 100% recycled plastic mesh and allow airflow through to the foliage of your tree, while still protecting the tree from browsing and from mechanical damage from brushcutter for example. These are well suited to planting conifers, which can grow too rapidly inside a solid tube. Some broadleaved species prefer airflow around the tree also, notably beech. A 1.2m treeguard is essential for protection from deer, while a 0.6m treeguard will protect from rabbit damage. They require a 1.35m or 0.75m stake to secure.
