Growth, Spurs, and Fruiting Habits of the Santa Rosa Plum in 
Relation to Pruning and to Soil and Other Conditions. — I 
A. — A tree which has been moderately cut back and thinned out each winter. It is growing 
in deep irrigated soil. (Photographed before annual pruning. Courtland, Calif., 
January, 1924) 
B.— Some 1-year-old branches, showing habit of producing spurs at almost all nodes on 
larger shoots and of bearing fruit at nodes where spurs are forming. The more 
slender shoots produce fewer spurs along the basal segment and here produce fruit 
at leafless nodes 
C. — Spurs (above) from a tree which has been well thinned out and moderately cut back 
each year and (below) from a tree which has been heavily headed back each year but 
only lightly thinned out
