Growth, Fruit Spurs, and Bearing Habits of Peach and Pond Plum 
Trees in Relation to Pruning and to Soil and Other Conditions 
A. — A 16-year-old Peach plum tree on which the 1-year-old shoots have been severely headed 
back each year. Note the vigorous wood growth near the points of pruning and the 
light growth elsewhere 
B. — Old Pond plum grafts top-worked on apricot. This tree is growing in fertile unirrigated 
soil, and severe heading back and thinning out each year are required to maintain the 
vigor necessary for the production of large fruit. Note that little fruiting wood remains 
along the older portion of the branches 
C. — Slender interior fruiting wood of a Pond plum tree which has been severely headed back. 
Note the short wood growth and the fruit on 1-year-old spurs which are leafless or have 
only small leaflets. These spurs will die after the fruit ripens 
D. — Vigorous fruiting branch on the outside of a vigorous Pond plum tree grown under irri- 
gation. (Note growth of twigs and contrast with C)
