I have a fairly large variegated Daphne × burkwoodii 4'wide x 3'tall. It sprawls out from the center rather horizontally, then grows upward, leaving the center rather sparce.
1. How far back can I prune this daphne without destroying it?
2. Is there a way to force growth from the center where the larger limbs grow out horizontally?
3. Occasionally, an unvariegated sprout appears. Is this common?
Any help would be greatly appreciated. I love the leave and wonderful flowers on this shrub.
