Bonide Mossmax Granules, manufactured by Bonide, is a specially formulated granule that's great for elevating lawns, flowers, and ornamental shrubs from invasive moss infestations and helps to improve a deeper green color in turf. 

This dual-action granule formula not only kills moss but also works to improve grass health by allowing nutrients, water, and air to penetrate the soil, promoting robust lawn growth. The active ingredients in MossMax Granules penetrate moss, disrupting its cell structure and causing it to die.

Bonide Mossmax Granules is a simple and straightforward product that delivers quick results even in larger treatment areas.

Tools Needed

You can apply directly from the container.

How to Use

  • Step 1: Determine how much Bonide Mossmax Granules to use by measuring the square footage of the treatment area. Find the square footage by measuring the treatment area's length and width in feet, then multiply them together (length X width = square footage). For normal infestations of moss, use 4 pounds per 1,000 sq. ft. For heavier moss infestations, apply 4 pounds per 500 sq. ft. 
  • Step 2: Open the lid to the container with a glove-covered hand. 
  • Step 3: Sprinkle the granules over the mossy area. Immediately after application, water-in. Wait several days until the moss turns black and dies, then gently rake it out.

Where to Use

Bonide Mossmax Granules can be used on moss on residential lawns and around flowers and ornamental shrubs.

When to Use

Apply anytime moss is actively growing and the soil is moist.

For best results, apply this product when the lawn is moist. Mow before application, to better expose existing moss and water in to activate the product.

Safety Information

Special Considerations

This product can burn delicate foliage if applied directly to flowers and ornamental shrubs. If contact does occur, use a garden hose to wash the product off of the plants immediately.
