Scotts® MossEx™ controls moss without harming your lawn. After you apply MossEx™ it will attack undesirable moss, causing it to turn black and disappear. It also contains nutrients to green your lawn and develop thick grass. Apply Scotts® MossEx™ in the winter or spring when moss is actively growing. It is best applied when the lawn is moist and tall grass has been mowed to expose low growing moss. We recommend using a Scotts® spreader to apply this product. For Scotts® rotary/broadcast spreaders, use a setting of 2 ¼ for the regular rate or 2 ¾ for the heavy rate. For Scotts® drop spreaders, use a setting of 4 for the regular rate or 4 ½ for the heavy rate. For Scotts® Wizz®, use a setting of 3 ¼ for the regular rate and 3 ¾ for the heavy rate. If additional treatments are needed, wait 2 to 4 weeks between applications. Please note, grass blades may turn black temporarily; however, this condition will disappear after mowing. One 18.37 lb. bag of Scotts® MossEx™ treats up to 5,000 sq. ft.

How to Use

  • Check bag for spreader setting
  • When using a Scotts® broadcast or Wizz® spreader, make a perimeter pass of your lawn with EdgeGuard® on to protect non-lawn areas. Then, make parallel internal passes 5 ft. apart to ensure even coverage.
  • When using a Scotts® drop spreader, start 5 feet from the edge of your lawn and walk the outline of your lawn. Then, make internal passes across your lawn, overlapping the wheel marks to ensure uniform coverage.
