Yucca Plants

Question

I have yuccas all over my front yard, but for the first time there are more brown leaves on them than green. When I would see this I would usually rock off the plant to the root and it would come back low and green. I can’t do that to all of mine or I will have an empty natural area since I have several dozen plants. Can you tell me why this has happened and if there is anything I can do about it?

Answer 1

It could be due to low humidity and dry air or some type of nutrient deficiency, such as nitrogen. I would simply remove the brown leaves and allow the green to remain.
