  • After the summer showers, pits of 45 cm3 are dug at 1.25 - 2.5 m apart.
  • The pits are left open for weathering and then filled and heaped for planting.
  • At the time of filling, apply 500 g of rock phosphate per pit along with top soil.
  • Planting is done along the contour in slopy areas.
Spacing :

Planting shade trees:
