Care and Maintenance

• With proper placement, manzanitas require little maintenance. Selectively prune to remove dead branches or to reveal structure. Avoid unnecessary pruning. Manzanitas are prone to branch die-back, caused by a naturally occurring fungal pathogen. When removing dead branches, sterilize pruning shears with alcohol between cuts to prevent the spread of the disease.
