You can also thank Julien as an answer to your own question. He will also be notified automatically, then.

I remember your original question, Winston, it was about 4 bay trees in pots, 3 of which look dead. It'll be the winter we had, they particularly hate cold winds, and in pots where you live, it's possible the rootballs froze for too long and the plant died. As Julien said, wait and see what happens for a bit longer.
