Growth, Fruit Spurs, and Fruiting Habits of the Agen Prune in 
Relation to Pruning and to Soil and Other Conditions 
A.— A thrifty old tree which has not been pruned recently and is not irrigated. This tree 
produces heavy crops of medium-sized fruit. Thinning out of fruiting branches is needed 
to increase the size of the fruit. (Vacaville, Calif.) 
B.— A 10-year-old tree. The short spurlike growth instead of longer twigs indicates lack of 
thrift, although the tree is in fertile irrigated soil 
C— Framework branch of the tree shown in D, indicating the fruiting habits of a tree on 
which all shoots and young twigs have been severely headed back each winter 
D.— A 16-year-old tree which has been severely headed back each year and is growing in fertile 
irrigated soil. It is very vigorous and produces heavy crops of fruit. (Niles, Calif.)
