Hi, I have an outdoor, 8' tall, >20 year old pony tail here in Hawaii. The tree has been in its present position for the past 3 years and has appeared to be quite happy there. In the past month, the top has turned from being vertically oriented to angling about 20 degrees toward the south. The vegetation appears otherwise normal, but the "drooping" is giving us concern. Is this normal? Can the droop be arrested? How would one do this? If not, is it the sort of thing that could continue?
