A sunny spot
She prefers lots of light, so try to plant her in a sunny spot. She'll tolerate a bit of shade, too
Well draining soil
She would prefer a free draining soil that also retains moisture. Try digging garden compost or well-rotted manure into her soil so it'll drain more easily.
Pruning
Give her a good pruning after growth season (summer) by cutting a few inches off her branches with a pair of sterilised shears or scissors.
