Transplanting large Phoenix roebelenii questions.
The previous owner of my house planted some pygmy date palms in 2 foot wide planters against the foundation in the front of the house. These plants are now much too large for the space and growing up into the eaves. I would like to to transplant them to the backyard. They are are multi trunked and the trunks are approx 6 foot tall, vegetation makes them 8 ft. How far from the base should I dig, and how deep? Any special handling advice? Do I want to use root stimulator after transplanting? Any other advice you might want to add?
