OF PLANTING WORK. MAKE MINOR ADJUSTMENTS AS MAY BE REQUESTED. FINE GRADE LAWN AREAS TO
A SMOOTH, EVEN SURFACE WITH LOOSE, UNIFORMLY FINE TEXTURE. ROLL, RAKE AND DRAG LAWN
AREAS, REMOVE RIDGES AND FILL DEPRESSIONS, AS REQUIRED TO MEET FINAL GRADE. LJMIT FINE
GRADING TO AREAS THAT CAN BE PLANTED IMMEDIATELY AFTER GRADING.
EXCAVATION FOR TREES AND SHRUBS:
EXCAVATE PITS, BEDS AND TRENCHES WITH VERTICAL SIDES AND WITH BOTTOM OF EXCAVATION SLIGHTLY
RAISED AT CENTER TO PROVIDE PROPER DRAINAGE. LOOSEN HARD SUBSOIL IN BOTTOM OF EXCAVATION.
FOR BALLED AND BURLAPPED, AND POTTED (B&B TREES AND SHRUBS), MAKE EXCAVATIONS AT LEAST HALF
AGAIN AS WIDE AS THE ROOT BALL DIAMETER AND EQUAL TO THE ROOT BALL DEPTH, PLUS ALLOWING FOR
SETTING OF ROOT BALL ON A LAYER OF COMPACTED BACKFILL.
PLANTING:
PLANTING TREES AND SHRUBS:
SET BALLED AND BURLAPPED AND POTTED STOCK ON LAYER OF COMPACTED PLANTING SOIL MIXTURE,
PLUMB AND IN THE CENTER OF THE PIT OR TRENCH, WITH THE TOP OF THE ROOT BALL AT THE SAME
ELEVATION AS ADJACENT FINISHED LANDSCAPE GRADES. WHEN SET, PLACE ADDITIONAL BACKFILL AROUND
BASE AND SIDES OF ROOT BALL, AND WORK EACH LAYER TO ELIMINATE VOIDS AND AIR POCKETS. WHEN
EXCAVATION IS APPROXIMATELY 2/3 FULL, WATER THOROUGHLY BEFORE PLACING REMAINDER OF BACKFILL.
WATER AGAIN AFTER PLACING FINAL LAYER OF BACKFILL. MULCH PITS, TRENCHES AND PLANTED AREAS.
PROVIDE NOT LESS THAN 3" THICKNESS OF MULCH AND FINISH LEVEL WITH ADJACENT GRADE.
