Summer Treatment* 



Owing to the strong growtli some of these plums and primes make both of 

 top and lateral (as illustrated in Figure 91 , eight j'ear old trees on tlie 1st DeoemVjer), 

 it is sometimes necessary to do some summer pruning even at this age. These 

 trees should be pruned about Christmas time, cutting back and thinning the 

 laterals and thinning out the tops. Figure 92 shows these trees so treated, the 

 following winter ; the leaders are jjermitted to go unpruned until the second 

 winter, or, if desired, they can be headed back during the summer, about 

 December. 



The following illustrations show the system of summer pruning (which gives 

 identically the same result as the winter treatment). Figure 93 shows a five year 

 old tree on the 1st December ; Figure 94 shows the same tree sunrmer pruned. 



Fig. 91. 

 Showing eight year old Prunes requiring summer pruning 



the leaders have been tliinntd out and the laterals cut close back. This tree was 

 thinned and the lateral spurs run over only during the winter, the leaders being 

 untouched until the following 1st December, when they were headed back as illus- 

 trated in Figure 95. By that date all the spurs had developed along the leaders 

 as shown in the illustration. Figure 96 shows this tree when the foliage fell in 

 the winter ; the s]iurs had developed well all up the leaders, and a comparison 

 made with Figure 97, a tree treated by the winter system of pruning, already 

 illustrated will show identically- the same results obtained by the summer systenr 

 of pruning. This tree onty requires the short top growth out back and the 

 laterals run over in the winter. , / , , 



Some plums, such as the Golden, Silver, and Sugar_ prunes may not require 

 this treatment, because they are not, as a rule, ramjiant growers. The lateral
