Here are 2 pictures of my palm. It about 5 years old. Looked great the first couple of years and we had a winter with a lot of snow. now it seems as soon as a green frond starts to emerge, the tips get brown almost instantly and the the whole thing turns brown and dies off. i have been using palm fertilizer by miracle gro and i even tried the micocorhizi but nothing seems to help. Any help would be greatly appreciated
