This tree was started about 5 years ago from a stem which had been cut off another tree. Now look at it!!!
My question: Is the bark and trunk supposed to look like this?? Kind of gnarly and like the bark is peeling off? It seems to be perfectly healty when you look at the leaves.
That said, the top looks healthy. I'd keep it as long as it's attractive.
The cocoon thing is nothing to worry about.
Also, I hope I'm right in cutting off the succors/suckers?? that started at the base? I've put them in water hoping they'll root as well.
