Hi to All: I brought my yucca cane inside about a week ago since the weather was dropping to freezing. It has since begun to have the leaves turn yellow starting from the bottom up on all the branches. I thought I let it get too dry so I doused it really well. The yellowing, however, doesn't seem to have stopped. Any suggestions? I don't think I over watered because I waited about a week before watering it. Thanks for any help.
