A male clone presumed to be a hybrid of C. equisetifolia and C. junghuhniana is reproduced by young, short cuttings in Thailand and India. Trees coppice poorly or not at all. Pest problems on casuarinas have been minor. Root rot in Florida and a blister disease in India have occurred. Many species survive fires well, but even light fires kill C. equisetifolia.
Some casuarinas can become pests.
C. glauca's vigorous root suckering has created problems in Hawaiian pastures and in Florida, where some counties have banned its planting. Additionally, leaf litter of some species may be toxic to some plants and increase soil acidity or salinity. Abstracts have been made by author D.L. Rockwood from documents or observations by the authors cited.
