40 ORANGE CULTURE IN CALIFORNIA. 



work than a skilled workman would do in a whole year. Do 

 not, under any circumstances, postpone from week to week the 

 cultivation of your orchard. Commence early in the spring, 

 running the cultivator almost continuously till late in the fall ; 

 then finish, as already stated, with a turning plow. 



After the rains are over, in the spring, use a turning plow 

 again, turning the soil from the trees, leaving the ground level. 



There is not a unanimity of opinion among horticulturists as 

 to the depth to which an orange orchard should be plowed. 

 Some favor shallow plowing; some, deep plowing. I approve 

 of and advise plowing not to exceed two or three inches in depth 

 adjoining the trunk of the tree, and within a radius of four feet 

 from it, increasing the depth gradually from this point to the 

 center of the spaces, the greatest depth not to exceed six inches 

 Two annual plowings are ample one in the fall, as herein 

 stated, finishing in December, and commencing again in Feb- 

 ruary or March. Thereafter during the year a cultivation not 

 exceeding three or four inches in depth will be all that will be 

 required.
