Evergreen 4in1 burnt my lawn

tajissangha

Hi everyone, Evergreen 4 in 1 I put this down a little heavy handed a few weeks ago, the smell seems to have gone. However I’m left with large patches of dried out brown/black grass. I have been watering thoroughly for weeks however no joy. I really don’t want to have to lay new turf I’m hoping by taking out the old stuff and over seeding this autumn may bring it back for next year? Any tips/ advice would be much appreciated. Thanks

Over application is very common. Just water thoroughly if you don't have decent rainfall where you are. That means an hour or two each night until the grass responds well enough, not a light sprinkling. 
It'll recover. 
It's very important to use these products correctly - ground should be damp, and it's always better to use less of it rather than too much. It can always be re applied later on if needed.

The black stuff is probably dead moss so the Evergreen is working. Just rake out the dead material - grass rake, not garden rake.

Fairygirl

Yes - @steephill is correct - most likely just the moss you're seeing 
If the grass doesn't 'spread' into those areas by the end of summer, you can re seed them too.

Ye I have read that it’s moss however it’s almost definitely the grass that’s burnt as you can see the pattern in which I’ve spread it. I literally Opened the Box and started pouring it out which in hindsight was a silly thing to do. I got a bit excited as I was planning on doing my garden this year. I will probably buy a sprinkler to ensure that it gets more water. I’ll post a picture now so you can see. Is it okay to overseer in summer then? As opposed to autumn? Sorry for the questions I am a bit of a newbie to all this. But thanks for the advice

Yeah, I've had that before. It was over application in my case and it bounced back after a while.

Divide that into about 3 sections and give each one about an hour each night, unless you have a day of rain.

Rake away all the dead stuff anyway, whether grass or moss or weed as that will leave the soil clear for new grass to grow.   You'll need to wait till September to re-sow as grass needs moist soil and cooler temperatures to germinate well.

For future reference, always read the instructions for any product before using.  Under doing it is ineffective and a waste of time and money and as you have now learned, so, in a different way, is overdoing it.

I have used 4-in-1 twice previously, and was extremely impressed with it.  However, I've had the same experience this year too.  I've been very patient, just thinking, maybe it needs more time, and sure enough, it is slowly responding.  I think it must be working, because now I'm getting a ring of growth around the 'burnt' areas, which is clearly higher than the area, outside this new ring.  Meanwhile, inside the ring area, which was burnt, I now see little shoots of grass coming through.  90% of the weeds are gone, rather than the previous 100%, which I found amazing.  I'm now going to water those areas, after having read a tip above, to stimulate more grass growth.  Thanks GW !

This is all amazing feedback guys. Gives me hope! I’ll keep watering. You have bought a sprinkler today so that should help I’ll post a pic once it’s up and running again. Thanks everyone!
