Growth and Fruiting Habits of the Duarte Plum in Relation to 
Pruning and to Soil and Other Conditions 
A.— Very vigorous shoots of the current season, growing on a thrifty tree which was severely 
headed back the previous winter. Note the growth of lateral twigs. (Compare with 
C and also with pi. 1, C. Newcastle, Calif., May 5, 1923) 
B.— Fruiting twigs and thin spurs on framework branches 5 and 6 years old. The twigs were 
produced the same summer as the branches on which they grew. The tree has been 
headed back each winter and is in fertile irrigated soil. (Compare with A. Newcastle, 
Calif.) 
C— A few 4-year-old fruiting twigs which were produced during the first season's growth of 
the large branch. (Compare with A and B) 
D.— A vigorous branch of a tree which has been pruned by heading back to lateral branches. 
Numerous spurs but only a few twigs have been formed. (Compare with A)
