Growth, Fruit Spurs, and Bearing Habits of the Giant 
Plum in Relation to Pruning and to Soil and Other 
Conditions 
A.— Trees which have been moderately cut back and the branches thinned 
lightly each year. (Santa Clara, Calif., October 7, 1924) 
B— Twigs and spurs from a thrifty tree 
C— Fruiting branch showing fruit on leafless 1-year spurs or those which 
have only small leaflets and on short spurs which are growing on twigs. 
The tendency of this variety is to produce twigs and not to retain spurs 
D.— Fruiting branch on a tree which has been severely headed back and 
thinned out each winter and is growing in fertile irrigated soil. Note 
that most fruits are at leafless nodes and leafless 1-year-old spurs, even 
on the vigorously growing branches
