1916 ANNUAL REPORT 



These first filler trees should be of some precocious variety similar to the 

 Lyon. The removal of the first fillers will leave the trees 30 feet apart 

 each way in squares. When the trees next become crowded, remove the 

 second filler trees indicated with the figure 2 in the diagram. This will 

 allow the permanent trees to spread out into the space occupied by the 

 second fillers, 2. When now the trees become crowded again, remove the 

 third fillers, 3 in the diagram, which will leave the permanent trees in 

 squares 60 feet apart, with a filler tree in the center of each square. (4 

 in diagram.) These center trees should have been planted with some 

 good variety desired permanently, and are designed to remove if the 

 trees again become crowded. Fillers 1 and 2 should be planted with 

 quick fruiting varieties, as they will certainly require to be removed. 

 Fillers 3 and 4 should be planted with varieties permanently desired, as 

 they may not require to be removed.

A variation of this order of removal would be to take out the fourth 

 fiJlers, 4 in diagram, before the third fillers are removed, leaving the rows 

 60 feet apart and the trees 30 feet apart in the rows. If the trees then 

 should not grow so large as to require further thinning, this will give 

 an orchard arranged on a plan similar to some of the best lemon groves — 

 a plan favored by some good growers. In this case the trees will come 

 close together in the rows, and if the rows are run in opposite direction 

 to the prevailing winds, each row will form a windbreak for the next 

 row* Again, this plan leaves a good space between the rows one way to 

 accommodate the hauling of fruit and the distribution of water. 



This plan of planting will give approximately 96 trees per acre when 

 first planted, 48 trees per acre with the first fillers removed, 36 trees per 

 acre with the second fillers removed, 24 trees per acre with the third 

 fillers removed, and 12 trees per acre with the fourth fillers removed.
