Q.Pygmy palm
After a freeze last year, my Pygmy Palm lost its leaves. It has 3 stalks, only 2 grew back palms over the summer. The third is still green but won’t grow palms. Can I make it grow again?

New fronds can only grow from the crown. If they do not emerge, the trunk will likely die.
Provide optimum care and hope for the best.
