24 h Soaking seeds in warm water for 24 hours or immersion in diluted gibberellic acid solution promotes germination

Fresh mature seeds have high fertility rate and germinate readily; pre-soaking or scarification recommended

Sowing

Substrate

sand and soil mixtures, well-drained sandy or loamy soils
