I fell in love with a picture of this little rose and, on discovering that it was a "patio rose", I ordered one which came today. In good condition BUT the root system is very big! I only want it in a pot on the postage stamp size patio. Can I cram all the root system in or can I trim any off ? I was hoping to grow it in a pot about 2 foot in diameter. Advice would be apprec iated thank you, Jenny namaste
