Here the result. The crown looks like bitten by a rabbit. We will have to wait for new growth this summer. The old yellow needles will fall off. In a few weeks the tree will shine I hope. The pot is fine, it will stay for the time being. It was not repotted for ten to fifteen years. This would have made us nervous some time ago. now we know that this tree can stay without repotting for way more than twenty years. Anyway, bonsai is fun. This was a nice birthday present! Now I am not disappointed anymore.
