I have a pretty mature coccothrinax that has been deficient in something for quite a while that I want to address. The fronds are small in size for the maturity of the palm and they barely grow out away from the center when the new ones push out. I can get some pics if helpful, but just on this description is there a common deficiency that causes this? It has been going on for a while....yearish or more....I have just neglected it and would like to try and get it healthy again. thanks for any input....
