I have a lime/lemon tree. Not sure if it's common, or unusual. We thought it was just limes, but it gives both at different times of year. It seems to be sick. Branches are barren and the buds aren't turning into fruit. Branches are also brown at the ends, instead of green. Any telltale ways to know if it's sick? Also, how to correct the problem? Or does it just need to be cut down and replaced?

This can be caused by too little water. I would provide extra water to the tree and that should help. By the way, it is a lime tree. Limes are normally picked unripe (green) but if left on the tree will ripen to yellow.
