Emma just take a leading shoot and nip it off, about 6 inches, dip in hormone rooting powder and pop it into some compost. It will do equally as well if put straight into the ground, put it aside and almost ignore it apart from watering. Yes there is a difference of opinion re pruning, but all your'e doing is reshaping of the top.
As for soil I've seen them do well in all types of soil, but sun is best. I've also seen them in very windy places and they still survive.
All I can say is if it's doing well where it is then just be happy for it. A happy plant is a healthy plant and age makes no difference if your'e happy.
