I have two yucca plants that look really “yucky”. This is the fourth year that I have had them and they have become so big. The leaves (or stems) have brownish or rust colored areas on them and some are a yellowish green and brown. Some of the leaves pull off easily and I have removed them but the other ones don’t pull off easily. I’m wondering if I can cut this way back or how I remove all the bad leaves, which is most of them. They have become so long that they are covering up some of my other plants. Am I doing something wrong that the leaves are looking like this? Last year they both produced their first flower. What do I do with the big, thick stalk that is left? Any help would be greatly appreciated. I’m about to pull them up out of the ground! Thanks!
Sorry it took me so long to get back to you. I’ve been doing some research and called a couple people I know who also have yucca plants and I haven’t come up with a satisfactory answer. From what you have told me, it sounds as if the stalk should be cut back. I would like to suggest that you call the University of Minnesota Yard and Garden Line; it is possible that someone there will be able to help you. Good luck!
