How to Kill Moss in Lawns

How to Control Moss

Iron-based moss control products, such as Scotts® MossEX™ or Scotts® Turf Builder® with Moss Control which also feeds the lawn, are very effective at controlling moss. As with most moss controls, these products are most effective when applied while moss is actively growing, which is usually during the cool, wet spring and fall. Before applying, mow the area short and remove the clippings to expose the moss. Shortly after treatment, the moss will turn black and die.

How to Prevent Moss from Returning

Control of moss requires more than just killing off the existing moss in the lawn. The best way to prevent moss from returning is to correct the underlying reason the moss began growing in the first place.

If areas of the lawn are receiving less than 3 hours of sunlight per day, trim tree branches to allow more sunlight to reach the lawn. For areas of the lawn that only receive 6 to 8 hours of filtered sunlight or 3 to 4 hours of direct sunlight, plant a shade-tolerant grass.

Good lawn practices will help your lawn grow thick and keep moss at bay. Feed regularly and mow at the highest recommended height for your grass type to encourage deep rooting.

Moss grows better than grass in wet, poorly drained soils. Aerate compacted soils and incorporate rich, composted material, like Scotts® Turf Builder® Lawn Soil™, to help improve drainage. Only water the lawn when necessary — just one inch of water per week is all most lawns need.
