I enjoy queen plams that look approaching the tops own be cut rotten .what can i do to stop this? ...

Name that plant?
Answers:    I am not sure from your description what is going on, but Queen palms commonly suffer from "frizzle top" which is caused by a manganese (not magnesium) defect. You can buy manganese sulphate at a garden center to correct this. See the following link for a picture of frizzle top and some other queen palm culture discussion.

What is the best path to pickup black...
I would own to see it. I have queen palms too. My tallest ones are going on for 25 feet high-ranking and the shortest about one foot. They are not supposed to be pointy. The top palm leaves arch sour from the trunk. This is normal.
