Hi to everybody.
I am a newbie, this is my first time in this group - sorry for my
"rusty" english.

I am looking for some help regarding my Phoenix Canariensis palm.
It is about 10 years old and it has grown pretty tall.
Every winter I have protected the trunk and the leaves with a kind of
cotton cover like the one used for strawberries.
Now it is hard to cover the leaves, cause it is so tall. Also I noticed
that the leaves in the palm's centre get damaged in the points where I
roped them together.
In spring those leaves break in these points and I have to cut them
down.

My questions a
Do I have to protect the leaves during winter too or just the trunk?
How should I cut the leaves off to obtain shortly and densely leaves?
How do I obtein the palm to grow high and how to grow large?

Thank you for any help.
