I have a deciduous daphne that is 5 years old, or older; it blooms in the spring, before the leaves open.
It is lovely, but is getting too big. Can I prune it? If so, how much and when?
Daphne’s require minimal pruning. You can take out dead, diseased, damaged or crossed branches in early spring, and even remove oldest growth at ground level. But in general, you should cut back the young shoots minimally.
After early spring blossoming , the deciduous daphne will start setting its buds along its branches, so pruning should be done in late spring to maintain height and shape. But be aware that daphne’s don’t tend to bounce back from severe pruning.
