Deals with moss without damaging the lawn. It's also allowed the lawn to recover before I began to tackle the weeds! I reckon the stronger the grass, the weeds don't get too much of a toe hold. And no ugly blackened moss to deal with. Plenty of scarifying and raking involved though - never fear!

I feel two applications advisable when there’s a serious infestation. But good results otherwise.

Used as a mosskiller in a sprayer this time.
The only complaint is it was difficult to dissolve even using warm water as suggested.
In the end took the filter out of the spay pipe and it worked well after that

Eradicating moss in lawn which is what it is for.
Easy to use and does kill the most but requires repeat use if there is a lot of moss.

Have used the multipurpose Mossoff,in the past and found that it worked well.So I thought I would try the Mossoff formulated for grass as products used in the past have caused staining.

I ordered fertiliser that did not contain ferrous sulphate as I do not want to mark my paths and patio. Excellent coloured granules which are easy to see where you have been. Brilliant.

It cleared a lot of the weeds but not all. That was after giving the lawn a strong dose of product. Will need another dose before all he moss has been killed.
