Propagation Method
Seed Information
Seed Collection
Pick greyish cones from shrub. Dry in paper bags to open. Sieve seed to isolate. Female allocasuarinas often carry ripe or ripening fruit at most times of the year.
Seed Treatment Method
Smoke Smoke treatment improves germination in some species. Smokey products, e.g. smokey vermiculite, can be purchased and applied to the sown seed, or sown seeds can be treated directly with smoke from a source such as a drum with a fire and hose.
Seed Treatment Notes
Seed loses viability quickly once released from the cone. The seed should be sown fresh or stored at 3-5°C to maintain long term viability.
Germination Time
10-45 days
Cutting & Division Information
Can be grown from cuttings of semi-hard wood. Coppice shoots taken from cut stumps or damaged plants will strike readily. Allocasuarinas have a symbiotic relationship with nitrogen-fixing root actinomycetes (Frankia sp). Inoculating potting soil with divots taken from beneath mature plants may be beneficial.
