Artificial plants and trees for "outdoor" use:

We now have a wide range of artificial plants and artificial trees for "outdoor" use. These items are manufactured with specially tested raw materials. These raw materials make these products long-term UV resistant (resistant to sunlight, so do not discolour). As a result, the products are assured of a long life and color fastness. Artificial trees with a hardwood trunk are ideal for outdoor use, but ...

Our advice, please note this: To prevent water from reaching the trunk, which could cause the water to freeze in the winter and cause the trunk to crack, we advise you to coat the trunk with a hardening coating (which makes the trunk becomes really watertight) and finished with polyurethane foam. The seasons certainly have an impact on the quality of the products and the natural trunks can certainly rot, if they have not been treated (with clear varnish for instance) well.
Outdoor use is at your own risk and without any warranty.
