You will now need to spread the Disease Ex on the grass as soon as you have filled the spreader. You can disperse the Disease Ex in two stages if you want.

To begin, activate the edge guard and move it around the perimeter of the outside boundary. Next, deactivate the edge guard and then begin spreading the product inside. To completely cover the entire yard, you can walk the rows with the machine spreader following any of these two approaches:

  1. When pushing from one row to the next while utilizing a spreader, the distance between the spreader and the wheel tracks should be approximately five feet. It applies to a broadcast or rotary spreader. Moreover, a broadcast spreader disperses its coverage to a far larger area. 
  2. If, on the other hand, you are operating a drop spreader, you should stride the spreader by creating rows beginning at the place where the last row ended. However, a drop spreader doesn't spread very far.

4. Remove Products Away From Any Hard Surface

It should be no surprise that the Disease Ex will come to the surface edge of the yard in some capacity. So, after you have finished filling the lawn and notice some of the Disease Ex granules, it would be best to sweep them back to the grass.
