I carefully planted my sago's in patio pots, huge pots, and left the ball half (or about) out of the dirt. THey were wonderful during the summer, but during winter and it wasn't that cold this year they began to fail. First the green leaves turned down almost hugging the pot, then the leaves turned sort of a hay colored - I did move them to more light thinking that is what they needed -it appears dead. There are little starts in the middle of the pod - what to do? should I cut off the dead? This is my first experience with this palm and I live in Arizona. Can you help?
