Propagation
Seeds are the preferred method of propagation because they are abundant and easy to handle, but germination percentage...Read Mores can vary from 30 to 70% depending on such factors as species, season of harvest and the collection site within the tree canopy (El-Lakany, 1996; El-Lakany et al., 1989; Olsen et al., undated). Poor germination may result from high proportions of shriveled, empty, and insect-damaged seeds that can be separated from "good" seeds by a flotation technique that can improve the germination percentage (Sivakumar et al., 2007). Seeds germinate in 2 to 3 weeks. Some care is required to prevent diseases caused by overwatering and damage from predators like ants. The dioecious Casuarina species tend to produce seedling populations with 1:1 ratios of male to female plants, but the ratio may vary and individual plants may be sexually unstable (Boland et al., 1996; Yasodha et al., 2004).

Personally, I am not very fond of these trees from an aesthetic point of view, but environmentally, they seem to have their uses.
I believe that the fallen needles have to be gathered and removed if one wishes the trees to regenerate naturally, although I don't have direct experience to validate this point of view..
