Morus nigra, and requires more care in choosing a situation for it, Calcare- 
ous soil is said to produce the best silk; and humid situations, or where the 
roots of the tree can have access to water, the worst. A gravelly or sandy 
loam is very suitable ; and trees grown on hilly surfaces, and poor soils, always 
produce superior silk to those grown in valleys, and in rich soils. The tree is 
propagated by seeds (sown as soon as they are gathered), cuttings, layers, 
and grafting.
