What happened to my indoor Yucca?

Too much water? Not enough water?

Container no longer big enough for the roots?

Over winter, the leaves died but a few new ones have started to form. Is this normal?

 

It looks too dry from the photo. How much natural light does it get ?

 

It gets SOME natural light but perhaps not enough, it's at the opposite end of the room to the window. The edges of the soil seem to have curled inwards within the container leaving a slight gap all the way around.

 

Give it a drink and more light - it will come back

 

Move it away from the radiator, give it a bit more water and it needs strong light.
