The bark on my wax myrtle is splitting.
It has grown during the past 10 yrs. to about 10 ft., full & healthy. Within the last several months it shed many leaves & the bark is now split. What happened ? Dan Keen Naples FL email@example.com
Older trees can have issues with cankers.
Do a good examination of the tree; the leaves for pest or disease, the bark.
Look for signs of pests.
