I have two questions:
1. One of my semi-dwarf navel orange trees lost most of its leaves a couple months back.  I draped some thin muslin over it to protect the limbs and fruit from the hot sun, and have recently taken that off. There are many oranges on the tree, and it appears that there is limited new leaves, but several branches appear to be dead.  What do you think happened, and what do I do now?

2. One of my Hybiscus plants has tiny leaves, and regularly has several yellow leaves, and no indication of growth effort. What can I do?
