What can I do to help this Variegated Arboricola to grow healthy and stop wilting?
I am in Southern Florida. I was spraying my lawn with Ortho® Weed B Gon® Weed Killer For Lawns Ready-To-Spray2 which is near these plants. Prior to the spraying/treatment the plant was looking far better. The leaves were sticking straight out rather than drooping. I am not sure what to do now to nurse them back to health.
Please let me know if you need any additional information.
The active ingredient of the herbicide used is Dicamba Mecoprop. It also affects broad leaf shrubs and trees. From this pdf by the International Society of Arborists
Once the material is absorbed there is no treatment to alleviate the symptoms except to avoid watering and fertilization. Removal of the tree should wait the second year because often a tree will recover and over a period of one to two years will regain its former appearance.
Although this article is about trees there are many other references with the same conclusions:
