Watering. Water regularly during the first year to establish roots, then reduce frequency. Allow soil to dry between watering to prevent root rot.
Fertilizing. Fertilize in early spring with a balanced, slow-release fertilizer to support growth. Avoid over-fertilizing, as eucalyptus prefers lean soils.
Eucalyptus caesia is a moderately easy plant to care for if given plenty of sunlight and well-draining soil. It is drought-tolerant once established but does not like waterlogged conditions. Regular pruning helps maintain its shape and encourages healthy growth.
