This tree is grown from seed and cuttings. Seed should be collected when the fruit is ripe. It is cleaned to remove fleshy part. Seed is sown in sandy loam soil mix in a seed tray. Seed should be covered with bark. The tray should be kept moist in a warm place. Germination should take 4 to 6 weeks.

Cryptocarya woodii is also propagated from cuttings in summer. Dip the end of the cutting in a rooting hormone powder for hard wood to promote rooting. Place cuttings in a bark and polystyrene mix.
