Ligustrum Experiencing Sudden Wilt
Location: Central Florida
Species: Recurve Ligustrum
Watering: Twice weekly
Trimming: Every Six Weeks
Establishment: Six years
For the life of me, I cannot figure out what is happening with my hedge line.
I am currently sitting on approximately two acres with the ligustrum hedges going around the entire perimeter. The sides of the property have been established for about six years. Half of the rear of the property has only been growing for three years, wit the other half closer to five.
For some reason, I have an issue with one corner in particular. This corner has all of a sudden refused to grow. Every few weeks I experience the same consistent problem with different plants. One shrub will begin to show signs of wilt, then will slowly dry up. The leaves turn brown and eventually fall off. And in time, the smaller branches lose all color.
I began replanting in the same area and the new shrubs do well for about four months, Then they stop growing, and end up dying off just like the rest.
I have been told to stop watering, don't fertilize as much, don't spray any weed killer, and don't trim. I have tried all opinions and nothing has worked. I've been struggling for over a year now. I have heard phytophthora, sudden wilt, Verticillium Wilt, and a few other ideas.
Attached are some photos of my problems.
Any ideas of what I can do? Any fungicides I can spray? Any techniques to cure my problem?
