Spur Growth and Fruiting Habits of the Clyman Plum in Relation 
to Pruning and to Soil and Other Conditions 
A.— Shoots of An 8-year-old branch of a tree which has not been pruned for several years 
B. — Fruiting branch of a tree which has been severely headed back each year, with a 
heavy crop of fruit on the young spurs. Most spurs along the older portion of the 
branches have been lost, as most of the vigor is in the ends of cut-back branches. 
The tree is growing in fertile irrigated soil. (Compare with C. Niles, Calif.) 
C. — A 9-year-old fruiting branch of a tree which has been only lightly cut back and thinned 
out and is growing in fertile well-irrigated soil. Note the persistent and prolific spurs. 
(Compare with B. Courtland, Calif.)
