OK, this is a weird tree. I got one of the original bunch that were delivered in June. I put it in a pot in my back garden in Brighton. It did nothing at all for several weeks and then started producing 4-bladed side branches from the main stem. The main stem did not grow any taller, it just sprouted side branches. It did this for about four weeks, and stopped. About the middle of September, the weather turned and it was continually wet for about two weeks, so I decided to bring it inside, expecting it to go quiet for the winter. About ten days after this, it suddenly went crazy. It started sprouting new growth not from the top, but from most of the lower side branches. Then, the secondary trunk grew about 6 inches in a week and sprouted loads of new side branches wide 2-blade foliage. The primary trunk which was growing before has done nothing in this period. Either this is a very strange tree, or my WN is a bit confused. What is it going to do next?
