Biological Durability of Sapling-Wood Products Used for Gardening and Outdoor Decoration

Sapling-wood products from di erent wood species such as willow (Salix spp. L.) and Commonhazel (Corylus avellana L.) are frequently used for gardening and outdoor decoration purposes. Remaining bark is suggested to provide additional biological durability. Even for temporary outdoor use it seemed questionable that durability of juvenile sapwood can provide acceptably long service lives of horticultural products. Therefore, sapling-wood from seven European-grown wood species was submitted to laboratory and field durability tests. In field tests, specimens with and without bark were tested in comparison and submitted to di erently severe exposure situations, i.e., in-ground contact, and above-ground situations with and without water trapping. All materials under test were classified ‘not durable’ independently from any potential protective e ect of remaining bark, which contradicted their suitability for outdoor applications if multi-annual use is desired.
