Where more than one pollenizer is needed to overcome difficulties already 

 discussed in relation to coincidence of bloom, the following plan may be 

 considered : 



Plan C 

 Row 



1 All Mcintosh or other desirable variety 



2 All earlier blooming pollenizer 



3 All Mcintosh or other desirable sort 



4 All later blooming pollenizer 



5 All Mcintosh or other desirable variety 



6 All earlier blooming pollenizer 



7 All Mcintosh or other desirable variety 

 Etc. 



If a premium is placed on the desired commercial variety, the following 

 plan may be considered in an orchard of permanent trees :

X=Common variety 

 E^Slightly earlier blooming sort 

 L^Slightly later blooming sort 



In this case there will be two poUenizers to every seven trees of the main 

 variety. Each tree will also be in contact in some direction with both an 

 early and a late blooming pollenizer. Likewise each pollenizer will be in 

 contact in the same way with each of the other varieties. 



In case semi-permanent trees are planted in the orchard, some pollenizers 

 should also be included in the permanent rows. Otherwise the orchard 

 would be without pollenizers when the semi-permanents are removed. 



One of the most satisfactory ways to plant semi-permanents is to follow 

 the quincunx plan ; that is, plant them where the diagonals between perma- 

 nent trees cross. Thus : 



P P P

 S S

 P P P 



P=Pernianent trees 



S=Semi-permanents 



In this way the trees are crowded the least possible amount, and removal 

 of semi-permanents is easy.
