ANSWER: Hi Vicka, it sounds like it is stressing for some reason, probably in the roots, you didn't give me much information to go on, let me know where it is growing, the ground or a container and what type of care you have been giving it...Nick

QUESTION: it was growing fine,giving me healthy young leaves. Its in ceramic pot 10" with  special tropical ground from home depot, i watering once in a week. Myabe  its related to heating, it stays close to window. now it cold season, it they turn on heating system(it s close to hot pipe)
Shouls i spray with water or sdd fertilezer?
should i send foto of tree? i like this tree so much and wanna save it.

Answer
A close up of the leaves would be nice, it sounds like it is too close to the heating pipes and when they come on, the heat is radiating directly onto the plant; misting it frequently will help tremendously, but moving it away from those pipes would help also. Yuccas are pretty tough to kill, they will take a lot of punishment and neglect and continue to survive, but they will show their discomfort with symptoms like the ones yours is experiencing. Nick
