I've had this Yucca plant for 17 years and just recently the leafs are turning brown and dying off. I do have 2 pups on it one near the bottom about 4" up from the soil and the other 1/2 the way up. The plant is about 6' tall and just above the 2nd pup the stem seems yellow and the leafs are dying. The top of the plant is green looks good but it seems that it's succumbing to the other leafs fate dying. Anything I can do? It's indoors now in a non direct light but bright room.It did very well outside last summer early morning sun and bright shade during the day. Thank you for you help! Tim McLean p.s. I don't have a photo.
Some species of yucca only live for a few decades, so yours might be nearing the end of its lifespan. It could also have a disease. You may want to remove the pups and plant them separately:
