In  localities  where  the  frost  penetrates  deeply  into  the  ground, 
roots  must  be  taken  up  in  the  Fall  and  protected  against  freezing, 
and  in  turn  re-planted  in  the  open  ground  in  the  Spring.  This  is 
the  method  which  we  follow. 
Portion  of  field  of  first-year  belladonna  plants.    Inset  shows  an 
enlarged  branch  in  fruit  and  flower. 
The  plant  seems  to  thrive  best  in  deep,  well  drained,  moist  loam, 
with  an  abundance  of  lime.  After  many  attempts  at  soil  fertiliza- 
tion, it  was  found  that  stable  manure  was  the  best  fertilizer.  Various 
forms  of  fertilizer  mixtures,  such  as  are  used  in  drug  gardens,  will 
increase  the  growth  of  the  plant,  but  apparently  will  have  but  little 
effect  upon  the  alkaloidal  content.
