Spacing
The planting distance varies according to the variety and the fertility level of the soil. The main consideration in planting trees is planted of sufficient pollinators to ensure effective pollination. Usually one pollinator tree is needed for two to three large trees planted at 10 m distance or one row pollinator for two rows of main cultivar. For high density planting the pollinator tree is planted after every sixth tree in a row.
The most widely used planting system is the square system. In this system, the pollinators are planted after every sixth or ninth tree. The other popular system of planting is the rectangular system. In hilly areas the apple orchards are established by planting the trees on the contours so as to prevent soil erosion and reduce runoff.
