A shelter for a growing plant, such as a sapling, is disclosed. The shelter is formed by a tube (10) of spirally wound layers of paper or board glued together with a penetrating paper converting adhesive. The layers of paper or board may be treated by a biocide, which is preferably water-soluble. Such a shelter is formed to be biodegradable in a controlled manner, so removal of the protector is not essential once the plant has grown beyond the need for protection.
