Found this at the garden center. It's going to be a big bonsai 36-42" tall. It's in burlap but was overwintered in a huge black tub. Roots are growing through the burlap into the soil. I'm letting that continue thinking it will allow better development and naturally air prune. The foliage is so dense it's difficult to even see the smaller branches at the tips. I have taken off some structural branches that were causing swelling and one major part of a branch to allow light to the more desirable piece of the branch. Waiting till late summer to style. It seems to be pure clay inside the burlap. Guessing I can't repot till spring. Liking that it is in such a large container. Will let that ride as long as I can. How long can I leave it in there?
