I have had an indoor palm for 25 years, and the top has bent over. About two feet of the tree is bent over and weak. What can I do to help it? I have moved it for more light and fertilized. It was repotted about a year ago. The top looks healthy except the fronds are small. I have tried bracing the top and now the lower fronds have bent where they meet the trunk of the tree. It's looking very sad.
