Hello, 

 

I've joined this forum to ask this question, as we have made a huge mistake. We bought some evergreen 4 in 1, but were very naive and put too much on the lawn, leaving lots of black marks and holes. Considering the lawn was pretty much all weeds, it's a wonder it doesn't look worse. 

 

Here is a picture of the lawn as it stands now: 


 

Pretty bad huh? Just wondering what we can do to fix this, and hoping the blackness will not be permanent. I know grass can grow under the worst conditions, so we're hoping in time it will go back to normal colour.

 

Any advise in the meantime would be very helpful. 

 

Thanks!

Hi, the lawn will eventually grow back green but it might take a while as its been scorched.  Only thing I can suggest is loads and loads of watering to try and dilute the feed through the soil a bit.  Give it a good rake during autumn to remove dead grass and weeds etc, reseed it and top dress it with some top soil and hope for a damp warm autumn.  Might take a while but you'll get there with it eventually.  Think you'll find you're not the only one who has made this mistake - I know I have in the past.

Grass is very resilient and grows from the base.  It can survive intense grazing, wildfires and drought.  I wouldn't worry about it at all.

Don't panic - the black bits are probably weeds - they will die off - the fertiliser will help the grass to grow and spread and replace the weeds - as others have said give it plenty of water and try not to worry - it'll be fine in a month or two 

Phew, I think you've all put my mind at rest a bit! Would over seeding be overkill, or do you think this might help?

Leave it for a bit Matt, just water it loads.  Seed it in the autumn if it needs it.

how long after using evergreen complete can you put down grass seed as i have black patches please help someone

Brenda, those black patches are prob areas of dying moss.  I would wait a couple of weeks yet to see if grass grows there.

the black patches is dead moss/weeds, you need to rake the dead stuff up to allow for the grass to grow

I've just had this problem.  The newer grass from turf last year seems fine, but the thicker bladed grass which has been there ages has scorched and died in massive unsightly patches.  I had no problem with that grass.  There was really no moss that I could see, and even if there had been it didn't worry me.

I just wanted something thick for the kids to play on and it was a bit patchy in places.  I was really after fertilising rather than killing any weeds.  I don't even mind dandelions.  But now this product has really messed up my lawn with no warning, and just before visitors arrive.

I wish I'd left it alone.  At least it wasn't black before.  There was no warning this could happen.  I certainly won't ever buy this product again, or any Evergreen product.

States it clearly on the packet.

Biggy, I know what you mean.Thisn happened to us last year when OH treated the lawn to try and get it a bit lusher.

Overnight it turned black! We didn't have any weeds in it as OH had previously done the treatment for weeding and feeding. We were mortified despite the package warning, as we knew we didn't have any moss.

We think OH put too much on but oh dear, it was quite upsetting at the time! Crikey!

However, we kept off it and watered it well and eventually, after a month or so, it started greening up and the gaps began filling over and it turned out okay in the end.

So, dont  give up, it will come right. Give it time.

Thanks plant pauper, but I'm not seeing moss blackening.  The blades of grass have shrivelled and died as far as I can tell.  As Hazel suggests, I can only assume I applied too much and too unevenly, but it's weird how it only affected the older more established area of the lawn.  It had happened within a few hours of application.

And if it was too strong a dose, I feel the box should say something like "Apply sparingly as over-applying can lead to areas of healthy lawn becoming scorched and blackened", because that's what happened.  I thought at worst I would be wasting some expensive product rather than burning my lawn away with caustic chemicals.

Thanks for the benefit of your experience Hazel.  It's probably obvious I'm pretty new to gardening generally.  Patience is something I'm having to learn!

It's important to apply these products when the ground is damp. If the ground's very dry it can be an issue as it just scorches a lot of growth - the stuff you want as well as the stuff you don't. Over application is the main reason for it happening though. 

I'd get a hose on it and see if you can revive it a bit. Grass is tough and even dead looking bits will often revive after some moisture.  If any areas don't come away, you can reseed them after scratching the surface up and putting a little fresh soil/compost down with the seed.

Oh dear, we did that once, the lawn recovered ok, just water it regularly and sow some seed in autumn.
