Question
I live in Hollywood Florida and have several ligustrum in my garden, planted in the ground. They were probably planted in 1985 or maybe even in 1960. I noticed that on one tree about a quarter of the leaves have turned light green and are dried out and curled.  This damage is on the side of the tree facing south. Based on my reading of your earlier answer, this sounds like root rot.  Is there anything I can do before I lose the whole tree? Is there any way to determine if it is root rot or some other problem? I did not think to take a picture but I could do that, if it would help you to identify the problem. It is a very beautifully shaped tree and would be difficult to replace.  Do you recommend treating the roots, or spraying the tree? What about the other ligustrum trees which are not far away from the diseased tree.? I look forward to your answer. Thank you.  

Answer
Hi hedvah,

It may be root rot although if the tree has been there that long its probably not likely.  It could also be a fungus as it sounds like its spreading from the south side of the tree.  Probably brought on by over fertilization which maybe un balanced the tree metabolically.  In any case Atomic Grow will take care of the problem very easily.  Atomic Grow works very good on lugustrum.  It is applied by spraying the foliage.    kathy
