After collection, the seeds should be properly dried to prevent rotting or mould formation. The seeds should be stored in cool and dry conditions before sowing.
Asexual propagation
Aristida ciliata Desf. var. pectinata Henrard can be propagated through vegetative means. This can be done through root division or stem cutting. Root division can be done by digging out the plant and separating the root clumps. The separated clumps can be replanted immediately in good soil with adequate moisture. Stem cuttings can be taken from healthy and mature plants when they are in the growing stage. The cuttings should be planted in well-draining soil with adequate moisture.
