10% Indian grass, 18% Little Bluestem, 10% Canadian Wild rye, 4% Switchgrass 8% Vir-
ginia Wild rye and 18% Wheatgrass.
IMPORTANT!
To prevent damage to the Native Grass box
agitator and its drive components:
Do not transport drill with Native Grass box
loaded with seed.
IMPORTANT!
FOR NATIVE GRASS MIX ONLY
Powdered graphite (PN: 821-042C) must be
mixed with the native grass seed mix for proper
seed flow and metering.
Recommended usage:
Sprinkle 1/3 cup of graphite per 6 ft. of seed
box on top of the native grass seed mix.
For humid planting environments, double or
triple rate as needed.
