Sudden die-back syndrome
Branches die rapidly without obvious cause; thought to be linked to a combination of root stress, virus, and fungal issues. Remove affected branches and improve drainage.
Root rot (Phytophthora)
Most common cause of death; improve drainage immediately and avoid overwatering.
Aphids on new growth
Cluster at shoot tips in spring; a strong blast of water or insecticidal soap spray resolves most infestations.
