Winter Moss , Kill ?

Last year my front lawn got heavily infested with moss . I applied a feed moss-killer , then scarified it 4 weeks later . All was fine . Moss is growing again in the shady areas . I would like to apply sulphate of iron moss kill water mix at 4 gm / metre to keep it down as much as possible. I was thinking of doing this at the end of December . Is the treatment and timing OK ?

TIA

 

Hi Armandii , the front lawn usually never suffers from moss . It is in full sun and drains really well . I used to get a little moss behind a shrub but that was to be expected . But then after the 2013 winter the moss seemed to have spread over 50% of the lawn for some reason . So this year I was hoping to stop it getting a foothold with a winter moss kill treatment.

 

We also have a moss problem for the first time in a shady area. The only thing different is that we removed a large ash tree. Any advice appreciated. Thanks.
