If the drainage is poor, or the disease has made 

 considerable progress but has not extended throughout

 that recently has not been manured or used for tuberous 

 crops. But if such a place is not available heel them 

 in somewhere; change the old bed so the drainage will 

 be good — as, in one of the ways suggested under 

 Where to Plant, pages 157-162; apply a solution of 

 formaldehyde, as suggested above for an original plant-

 be accomplished even if the leaves are green, but not
