I wish I came across this thread when I started mine. I did not know about the soft wood and how easily it can mildew. I carved a face in mine. With the white bark it was a perfect Game of Thrones tree. The first carving was shallow and I coated it with lanolin oil to protect it. It was fine and survived through the winter. The next season I refined the face and added some red tears for a phoyo op right before the GoT finale. I forgot to protect it with oil before I put it in the greenhouse. I checked on it later to find the face black and rotting.
it survived but the face died.
The next season I removed the rotted area and added a wood hardener to anything exposed. I wired it as a windswept, but like someone mentioned, it's growth habit is straight up. So I'm thinking I will repot it as a cliffhanger sideways tree with the ends pointing up. It is a cool material to work with and I've gained some experience through failure. It's definitely not a complete fail and is a pretty interesting tree.
The wire is currently off now but it's dark outside so I can't get a good pic.
