I have a yucca palm, something like 4 feet high-ceilinged with 2 key stems. the top stem looks ok, but the lower one is having some issues. Its drooping and wilting and looks similar to its dying. Any advice? gratitude!
What time of daylight should you hose down...
Answers:    Parts of them die as they grow taller, and they die from the bottom up. As long as the main root contained by the ground is OK it will be fine.They are almost impossible to kill.I've lived surrounded by the desert for 25 years and they grow wild here I preference you had a picture, afterwards I could tell you for sure. I don't know where on earth you live but if it is cold there that probably have something to do with it.
