WATERING:
SPRING AND FALL PLANTED TREES AND SHRUBS SHALL BE THOROUGHLY WATERED THE DAY OF PLANTING AND THEN WILL BE WATERED EVERY 7 DAYS THROUGHOUT THE FIRST GROWING
YEAR. WHEN SIGNIFICANT RAINFALLS MAINTAIN M016TURE IN THE SOIL, WATERING FOR THAT PERIOD CAN BE DELAYED UNTIL THE NEXT 7 DAY CYCLE.
FERTILIZING:
INSTALLER TO AMEND 601L AS REQUIRED BY ON-5ITE CONDITIONS AND THE NEEDS OF THE PLANTED TREES AND SHRUBS,
FERTILIZATION SHOULD BE DONE IN EARLY SPRING OR LATE FALL, AND A WATER INSOLUBLE NITROGEN (WIN) 15 RECOMMENDED AS THE PLANTS WILL USE IT AS NEEDED AND IT WILL
NOT WASH OFF OR LEACH INTO THE GROUND WATER.
