C. glauca has proven widely adaptable. In Egypt, trees grow on clay to coarse smd, saline to calcareous, and dry to water-logged soils. In Hawaii, trees have been planted on parent basalt. No seed pretreatment is required. Early results of provenance trials in Egypt and elsewhere suggest substantial growth gains are possible through use of proper seed sources.
Irrigation is required to establish trees in desert areas.
C. glauca forms a symbiosis with actinomyeetes of the genus Frankia. . Spherical woody nodules, some exceeding 20 cm in diameter, are found in large masses near the base of the trunk and as deep as 10 m. Root nodules have been observed on trees in natural stands and on trees in plantations growing on very saline or water-logged sites. The greatest number of nodules are found in soils with pH ranging from 6-8. Crushed nodules or soil from beneath mature trees can be used to inoculate nursery seedlings.
