Propagation

Methods of reproduction

Can be used as live, cuttings, circle branch ( aerial pressing) and grafting methods of seedling. Since the root system can produce tillers, it is also possible to use the dividing method. However, live propagation has variability, it is best to use nutrient bags to propagate.

Generally choose this rootstock, when the diameter of the seedling reaches 0.7 cm, can be grafted. Available bud or branch grafting method. Time to winter and spring is preferred. The scion should not be too old or too young, to just peeled branches is appropriate.

In the scion collection 10-15 days before, remove the leaves, when the buds will be sprouting cut, the best results. Rootstock thick, accumulate nutrients, is conducive to grafting survival, bud 1 month after the untied, bud healing after cutting the anvil, prompting the scion sprouting growth, 1 year after the nursery planting.
