My female Sago palm opened up and produced large ball in center and is just not doing anything. Previously it always produced new branches shortly after opening up. Should I be doing something or just leave it alone?

I have a female Sago Palm approx. 10 yrs old that has done very well. It started to bloom this spring and went to the point new leaves should have started to open up but did not. Then it developed a new bloom over the top of the original bloom and stalled again. How do I get this to leaf out?
