We can use lawn moss killer as a standalone treatment to inhibit growth or as part of a moss removal program. If the moss is not too overwhelming we can often keep it at bay or even reduce its spread by regular use of a moss killer.
The traditional product and green keepers favorite moss control product is sulphate of iron; also known as iron or ferrous sulphate. Its chemical formula is FeSO4. It is the moss killing component of moss killers and lawn sand and is commonly sold in the green keeping industry as a fertilizer under the name of Ferrous Sulphate or Soluble Iron. It may also be combined with other elements and can therefore be used as a general fertilizer.
The most common way of applying a ferrous sulphate based kill lawn moss is to spray it in solution a week or two prior to raking out the moss. The moss is partially desiccated and is thus easier to remove. However, there are two other opportunities to use it that may make getting rid of moss easier and more efficient. Moss off is a natural chemical free and works completely differently to ferrous sulphate.
We can also use ithem after removal of the moss in the spring. Treating moss prior to removal will not kill all the moss; perhaps 20% to 50% will remain to re-infest our lawn. Therefore, if we treat what remains after raking we may well achieve upwards of 90% moss control. Ensure at least 4 weeks between applications if we are applying ferrous sulphate before and after raking. If we are over seeding, do this at least 24 hours after applying our moss killer.
Because the products of iron sulphate acidify the soil we must use them uniformly over the whole lawn otherwise we will create pH variations which will affect grass growth and may even increase moss infestations in future years.
