Maintaining cedars involves: Watering: Provide consistent moisture, especially during dry periods. Mulching: Apply mulch around the base to retain moisture and control weeds. Pruning: Trim dead or damaged branches, and shape the tree as needed. Fertilizing: Use a balanced fertilizer in spring to support growth. Pest Control: Monitor for pests like cedar aphids and treat if necessary. Disease Prevention: Watch for cedar-specific diseases and apply fungicides if needed. Protecting in Winter: Mulch around the base and consider anti-desiccant sprays to prevent winter damage. Always consider the specific type of cedar and local climate for optimal care.
