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