Q: Can you tell me what "blisters" mean on the leaves of a young daphne plant?
Daphnes are moderately hardy, short lived and known to up and die for no apparent reason, so I have not grown them. That said, my research says what looks to you like blisters may be an insect called scale. Take a sample of the leaf to and independent garden center or nursery where these plants are sold for a more accurate ID and recommendations for control. Best And Happy Yardening, Nancy
