GINSENG. SI 



heavy, it is advisable to use heavier material (Fig. 9) than lath, 

 strong enough to hold up any snow that may lodge on the arbor, 

 or, if plaster lath are used in such localities they may be made up 

 in sections or screens, of convenient size- These screens may be 

 removed in the autumn and replaced again in the spring before 

 the plants come up. The laths should run north and south when 

 placed on tlie arbor; this, however, is not absolutely necessary. 



The rafters should be so arranged that they are over the 

 narrow paths between the beds, as otherwise the water that 

 gathers on them falls down in large drops and washes out the 

 younger plants- In localities where there are very heavy rains 

 during the growing season, it is advisable to arrange the roof of 

 the arbor so that much of the water drops to the ground in the 

 paths, which can be done by raising one end of the laths (Fig- 10) 

 about one foot. This is especially advisable where heavy, soggy 

 ground is used. Raising one end of tlie laths has another advan- 

 tage inasmuch as it leaves an opening in the roof at intervals of 

 the length of the laths, which aids ventilation. 



The sides, or fence of the garden, should be constructed so 

 as to keep out cats, dogs, chickens, or an5' larger animals, and as 

 thorough ventilation by free circulation of air through the garden 

 is essential, the fence is best built of wire. On the south and west 

 sides the arbor should extend out far enough to prevent the direct 

 rays of the sun striking the plants- 



NATURAL SHADE- Ginseng can also be grown in the natural 

 shade of the forest. But when this is to be done, all small trees and 

 roots must be removed, and the ground prepared the same as has 

 been described elsewhere in this book. Every year the small roots 

 of the nearby trees must be cut off, or they will grow through 

 the soil of the ginseng bed, sap the ground of moisture, and rob 

 the plant of its nourishment.
