 Many growers start to pot Kuromatsu in the middle of March. In autumn, they prepare to cut the roots for the potting in spring. But it is hard to finish the work in the best season of cutting because of the large cultivation in Kyokushoen bonsai garden. He completes the work in the beginning of spring and then starts the potting in the middle of April when the buds come out from the seed leaf and many other growers finish the work.

 It is said, "Do not pot when the buds start to come out." About 5 years ago, he tried to pot after budding in the full knowledge of the best season. The percentage of rootage of Kuromatsu which is full of vitality was 95. After all, he succeeded the laborsaving way.

 Recently many growers wash the roots to remove the soil and use the new one in pots for the growth of new thin roots. However he uses the field soil in a pot following the traditional way.
