Keep soil evenly moist during establishment, then transition to deep, occasional watering as the tree matures to support strong drought resilience, healthy growth and its naturally elegant mallet form.

Is Eucalyptus spathulata – Swamp Mallet Drought tolerant?

As a young tree it requires regular watering, but once established Eucalyptus spathulata develops excellent drought tolerance. Despite its common name, it thrives in hot, dry and exposed environments and maintains its tidy, mallet-form canopy with minimal supplementary watering.
