There are two types of spreaders: broadcast and drop. A broadcast spreader will get the job
done more quickly, but is less accurate than a drop spreader, which "drops" the
application directly on the lawn. More passes will need to be made with the drop
All spreaders have a hopper (where you put the fertilizer), wheels, handle, on/off switch and a calibrator. The back of the lawn food package will give you the setting for your spreader.
Open the bag and fill the hopper on the spreader. Once you have the proper setting on the calibrator, it is time to start feeding the lawn.
Feeding the lawn is as simple as mowing it. First, make a header strip around the perimeter areas of the lawn. Watch the swath (the area where the application is broadcast) and make sure the granules fall on the lawn, and avoid getting it in gardening beds, driveways and sidewalks.
Turn the spreader to "on" and start walking, and turn it "off" when you
reach the area of your header strips. Don't worry if it looks like you are applying the same
area again, just be sure to turn if off as close as you can to where you already applied the
product. Continue going back and forth across the entire lawn.
For broadcast spreaders, the swatch should overlap a previous pass by a few inches. For a drop spreader, follow the wheel marks from a previous pass.
Once you reach the end of the lawn, turn the spreader off and return any remaining product to the bag.
