The Best Lawn Fertilizers for Moss

By Tammy Wood ; Updated September 21, 2017

In any lawn with spots of bare ground, moss can take hold. Another factor is if your lawn is in a damp and shady area--this is a prime place for moss to develop. Determining the reasons why you have moss is the first step in finding the best fertilizers for moss control.

Bare Spots

Find the locations in your yard where moss has grown; if the lawn surrounding the areas is bare ground with thinning grass, your fertilizer should offer substantial nutrition to that area. Use a fertilizer that is a timed release of nitrogen, such as a 10-6-6 fertilizer, to feed your grass and discourage the moss growth.

Damp, Shady Areas

Choosing a moss prevention fertilizer is easiest in a damp, shady area of your lawn. The best type of fertilizer to use in the shady portions of your lawn is one that is based on an iron compound, not nitrogen. Iron fertilizers come in two basic forms--iron sulfate and chelated iron--and each are equally effective in inhibiting moss growth. The iron compound fertilizers are most commonly found in liquid format, and will specify that they are a soluble iron fertilizer (typically 1-3-1).

Excessive Moss Coverage

Extraction of the moss is an option if the moss has overwhelmed a certain area of your yard. The extraction process is more commonly referred to asde-thatching, and it will generally remove 75% of the moss in your yard. After de-thatching the moss infested area apply a balanced multi-purpose fertilizer (such as a 5-10-10) for a healthy, beautiful lawn.
