brown leaf tips

I have a 2 year old crepe myrtle, about 6-7 ft high. The tips of almost all of the leaves are turning brown and dying back from the tip. What can I do to fix this? I also have a young avocado tree, ~4 ft, with an identical problem. Thanks so much for the help.

This indicates a watering issue. Either the trees are not getting enough water or there is something affecting the roots that is preventing the roots from taking up water.

Check for root rot:

If you don’t find root rot, increase water to the trees.
