TreeProtect BIO is made from biopolymers and is bio degradable.
The tree trunk protector Bio is available in the colours white and green. TreeProtect BIO has optimal air gaps. Therefore the tree gets enough air and light. Infraction by insects and rot of the tree bark is prevented by the air gaps.
TreeProtect Bio protects trunks to a diameter of 11 cm. For larger trees two or more TreeProtect trunk protectors can easily be linked together. Each year the trunk protector must be adjusted to prevent the trunk protector growing into the tree trunk.
