Why Does My Lime Tree Have Dry Leaves at the Tip?
It's planted on the ground and it looks really healthy except on the tip where the leaves seem to be turning brown or drying.

This is normally an indication that the plant is not getting enough water. I would increase water to the plants. It is also possible that the tree has a fungus. Just to be on the safe side, treat the tree with a fungicide.
