These are a wonderful alternative to the prickly holly types! One good pruning a year seems to suffice. Ours get full sun, from sunrise to 2 pm and stay relatively dry, which probably explains why they don't require much pruning. I've considered transplanting to a more ideal location; but they're so established, I'm reluctant to move them.
