Spotted gum (Corymbia maculata)

Spotted gum

Spotted gum is a gorgeous but very large relative of the Eucalyptus that is cultivated for use as a shade tree in parks or along streets, basically because it is too huge for most domestic gardens and lawns. It has a lignotuber, which has the same function as a tuber in smaller plants but is gigantic, with the above-ground portion often spanning several feet wide.

Garden Soil

Soil Type

Water: Spotted gum thrives in dry, nutrient-poor Australian soils, requiring watering every 1-2 weeks due to its drought tolerance. Preferring well-draining soil, this evergreen tree maintains consistent water needs throughout the year, reflecting its adaptation to open woodlands with infrequent rainfall.

Pruning: Spotted gum thrives with early spring pruning, focusing on removing dead or crossing branches for healthy growth. Thinning interior branches improves airflow and light. Make clean cuts above buds to aid healing, minimizing infection risk and promoting vigorous new growth during the plant's growth cycle.

Propagation: Spotted gum, a native Australian tree, is valued for its timber and ornamental uses. Propagation is best done with semi-hardwood cuttings, enhanced by rooting hormone and well-drained medium. Optimal humidity and warmth promote rooting, while careful maintenance during establishment ensures young plants thrive.
