Frequently Asked Questions (FAQs)

1. Does nitrogen get rid of moss?

It can be applied to lawns whenever moss is actively growing and will kill moss in days. The combination of Iron and Nitrogen will also green up and strengthen your lawn.

2. What is the most effective moss killer for lawns?

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.

3. What will kill moss but not grass?

Iron sulfate will start damaging moss in a matter of hours and effectively kill it within two days. This ingredient is commonly found in fertilizers and won't harm your lawn's grass. Glyphosate, on the other hand, is non-selective and will kill both the moss and grass it comes into contact with.
