Many thanks for your message. It's been in that pot since I've had it - just over 2 years. It feels heavy. Should I re-pot, then?....

Yes, time to re-pot with new soil, I would leave the pups just as they are.

How often do you water it? Do you keep the soil moist or dry?

Your Yucca cane roots are dying and the upper portion now has no way to absorb water. That is why the leaves are wilted. The basal shoots emerge only when the roots are mostly dead and are a sign that the plant is making a last desperate attempt to survive. My guess is you will also find that the outer bark is starting to pull away and is becoming papery. Finally, the heaviness of the soil indicates that it is too wet.

Yuccas require lots of sunlight and soil that dries out at least a third of the way deep into the pot. I suspect that the combination of inadequate light and too frequent watering have caused the roots to rot. I am sorry to say that the chances of recovery at this point are unlikely.

Yuccas are a desert plant and like it dry, dry, dry. Pretty sure its nearly impossible to underwater them. Pull it out of the planter and look at the roots- if they're a mess, clean it up the best you can, and put it in new, well draining soil. The fact that there are pups makes me think it may survive. You could also cut the trunk, and root it in another pot. My experience with yuccas is they root rather easily, although I don't have this particular variety.
