Over 17 years, trees on alluvial soil with a significant inclusion of pebbles reached a height of 25–29 m, with a trunk diameter of 50–60 cm.

When the temperature drops to -8 ° C, leaves and shoots are damaged, in winters with short-term frosts of 11-12 ° C it freezes to the root, prolonged frosts of 9-10 ° C are critical.

Crosses easily with other species. Artificial hybrids with Eucalyptus rod-like were obtained and natural hybrids with Eucalyptus globulus subsp were established. maidenii .
