Moss Control in lawns and beds

The moss problem has been worse than usual this year because of the continuous rainy weather. Moss loves shade and wet areas. Moss Control products for plants contain a natural iron compound which not only kills moss but turns grass and leaves dark green. Many fertilizers contain iron. A minimum of 5% iron is necessary for moss control. I use Ferrous (Iron) Sulfate which is available from some full service nurseries.

Moss Out for Roofs and Structures contains a natural zinc compound which is non-staining and non-corrosive to wood, concrete, asphalt and metal.

Moss does come back and requires repeat treatments at least once a year. I treat twice a year in problem areas. Iron compounds will cause rust stains on concrete. Brush granules off concrete before they become wet. Surface and sub-surface drainage will also reduce moss.
