I just purchased two red tips in April 2011. I have one in full sun and the other in partial shade. The one that is in full sun has leaves on it that are drooping. The one in partial shade has leaves that are upright and doing good. I am trying to find out what is wrong and what should I do with the one in full sun. I did scrape the branch and it is still green, so it is not dead. How can I save it?
