My female sago has doubled bloomed which has never happened before. Live in San Diego and we more rain last year, maybe related. It has been doing nothing on top of the other bloom with the red seeds and in the meantime, the fronds are all yellowing. All my other male sagos bloomed normally in early summer. I am afraid I will lose it and it is quite large. The nurseries I have talked to say just to leave it alone. So I am not sure what to do?
I have seen female sago with no fronds and a bloom head only. If the fronds look yellow and sickly it is okay to cut them off. You will have a trunk with the seed head perched on top. I think the exotic look is okay. After the plant decides to stop producing seeds the fronds will start in the center. Maybe not till spring even. It is a wait and see situation, but larger sago are very hardy. The new seed growth is your confirmation that the plant is alive and well.
