This palm is 30 yrs old. Was given to me and is winter in, summer out. The pot is plastic, old and cracked, but more the plant is huge. The trunk is 15" tall and the fronds are huge. It is winter now in east TN and has overtaken my livingroom. The lady that had it can no longer cares for it, so I have it now. It is about 80 lbs and needs a new pot. What do I need to do?
