Propagation of Kurodake:Seed - surface sow as soon as it is ripe in a greenhouse at about 20°C. Do not allow the compost to dry out. Germination usually takes place fairly quickly so long as the seed is of good quality, though it can take 3 - 6 months. Grow on in a lightly shaded place in the greenhouse until large enough to plant out. Seed is rarely available. Division in spring as new growth commences. Divisions from the open ground do not transplant well, so will need careful treatment and nurturing under cover in pots until at least late spring. Division is best carried out in wet weather and small divisions will establish better than large clumps. Another report says that you can take large divisions from established clumps and transfer them straight to their permanent positions, misting or drenching them frequently until they are established. Basal cane cuttings in spring.
