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.

Have used this product but find it isn’t as strong as the chemical moss killer I’ve used before

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.

A very kind to garden and kids and pets alternative, heavy moss will take a couple of applications at it's recommended highest strength (lowest dilution)

This does what it says on the tin and I used it because of the non chemicals aspect especially because of children playing in the area.
