The leaves are cut in the form of a cone, so that they easily flowed water. Also shorten the roots, leaving the rhizome approximately 10 cm in length.
Remaining after digging a bush, old and completely healthy links, on which there are no leaves and living roots, are planted on a bed. Of these, dormant buds will sprout next year.
During planting should take into account that the rhizome should be at ground level. Depending on how long the roots are, they dig a planting hole of the required depth. At its bottom, a small mound is constructed, on which the roots are located. Pressing a seedling slightly to the ground, it is covered with a layer of soil.
