CULTIVATION OF UDO. , 19 
occasionally there are three. After the removal of the last crop the 
rootstocks are buried and allowed to remain over winter. In the 
spring the mounds are opened and rich manure is applied in trenches 
running on both sides of the plants. Throughout the summer the | 
plants are allowed to grow and are again cut down in autumn and 
treated in a similar way to that just described. The life of the kan 
udo rootstock is more than ten years, but beyond that age its use ceases 
to be profitable. 
Although generally grown from seed, this variety can be repro- 
duced from root cuttings, though the latter method is considered less 
practicable, owing to the fact that the large root cuttings take up 
more space in the field. 
The season for kan udo is October and November, and being the 
earliest variety and occupying the fields to the exclusion of other 
crops it is also the dearest, sometimes selling for as much as 25 cents 
for a bundle of 16 shoots. It is not otherwise preferable in any way 
to the other variety, which first appears in the HELENE! toward the end 
ot November. 
THE CULTIVATION OF MOYASHI UDO. 
The moyashi or forcing udo is grown from root cuttings, which are 
purchased by the growers from special cultivators who have their 
seed beds on the slopes of Fujiyama. These young sets, which have 
been grown from seed the year before, are dug in November and kept 
all winter packed in straw. They are bought in early spring by the 
cultivators and kept ready for planting, wien! is done during March 
and April. 
The root cuttings are laid lengthwise in a shallow trench about 4 
inches apart, and in the space between them a small quantity of rich 
manure is placed. They are then covered with 2 inches of soil. As 
the leaves appear, the trench is gradually filled about their bases, and, 
with the usual cultivation to keep down the weeds, the plants are 
allowed to grow until the end of October, or until frost. These two- 
year-old plants are then dug, the dead stems are removed, and the 
plants packed away in a dry place until wanted for the forcing bed. 
They may be kept for several months in this dry condition without 
injury. 
The forcing bed is made by digging a trench 3 feet wide and 2 feet 
deep and puttmg on the bottom a thin layer of barley husks or a 
sprinkling of bone dust, over which is spread an inch of rich, light 
garden soil, mixed with about 10 per cent of leaf mold. 
The dry udo sets, which are kept in stock, are packed as closely 
together as they can stand in the bottom of the trench, which is filled 
in and heaped up with the same light soil. In about fifty days the first
