(6 ") inches of compost and till into a depth of six (6 ") inches
of the topsoil. Apply organic fertilizer such as Sustane or

limits of steel curbing and obtain Owners approval prior to
installation.
2. All steel curbing shall be free of kinks and abrupt bends.

sides of the hole should be rough and jagged, never slick or debris shall be removed from the site as work progresses. Keep
glazed. paved areas clean by sweeping or hosing them at end of each
work day.
H. Percolation Test: Fill the hole with water. If the water level does
not percolate within 24 hours, the tree needs to move to another END OF SECTION
