Weeds and Moss in lawn

MouldyOldDough

We have way too many weeds and moss in our lawn - with ropey grass

The wife bought a large box of grass "improver" granules and plans to cover the lawn with it today - I had said 3 in one (ie Moss killer / fertiliser and weed killer) but she is adamant that the grass will be killed off by the weedkiller and we need to feed the grass first !

Sorry, what's the question?

From what you've said, I think I agree with you, I'm not sure why she thinks putting 'grass improver granules' (fertilizer?) will kill the weeds, unless she's saying to put fertilizer down first (which will likely bolster the weeds) and then weed killer after?

She could be confusing the general advice that fertilizing a lawn can help boost healthy grass, which naturally chokes out weed - but missing the point that if the weeds are already established then it's too late. The idea is to have a densely packed garden of healthy grass, so the seeds of weeds don't have anywhere to take root and grow.

Best thing imo to do would be to apply a weed & moss killer and then 6 weeks after, re-seed any gaps/sparse areas.

You are correct, but my advice for a Happy Easter is just grin & bear it, and try to suppress the "I told you so" in a few weeks time, when you can apply the real broad leaved lawn weedkiller, which you will have to buy yourself as obviously Mrs MoD cannot be let loose in B & Q etc on her own 😁

So what has she actually bought? Just an N -P-K fertiliser? Sounds like she may have paid over the odds if it's labelled 'grass improver' rather than good old Growmore. But it won't do any harm. It's what I do now and then spot weed any big ones. I don't mind a few flowers coming up in a lawn. I think the 3 in one stuff is overpriced and overrated.

I prefer to rake out any moss , as the moss killers turn it black which looks awful ,and you still have to rake it out once its dead.

It's not cheap, but I use Mo Bacter for moss. No raking needed
