That all depends on what the problem is if it is root bound all you need to do to fix it is transplant it inot a bigger container where the roots can stretch out.
Palm trees can last a long time with little care. Good healthy soil is important for your root system. Some roots can grown out 20 feet from the tree. They thrive in sandy soil so be sure to fertilize. Water twice a month using slow drip water over a period of time.
