recommendations for lawn fertilizer please

ryan 3ryan 3 Posts: 9

hi guys, i recently laid a turf lawn with my brother around 8 weeks ago, around 4 weeks ago the grass has started to become yellow and dead in areas. i'm looking a good fertilizer i can put down to maybe help its colour and growth, i cant understand why the lawn has started to get like this. Maybe it has a disease? 

All the usual b&q and home base products (evergreen 4 in 1 and after cut etc) state NOT to use on a lawn under six months old. 

Thank you for all you help guys

    Sounds like a lack of nitrogen.

    Don't know what to recommend exactly,

    Maybe a liquid fert at half or a quarter strength.

    Something with NPK.

    Hi ryan. They're right - new lawns shouldn't have feed on them for a while. The problem is more likely to be the conditions below the turf. What was the ground like when you laid the turf on it? Poor drainage leading to waterlogging will cause grass to die off. Another reason is the turf not coming into contact properly with the soil below so the roots will die in those areas. Can you give us all a bit more detail so that we can offer a few more ideas? image

    I agree with Fairygirl, no feed on new lawns and the problem is more likely the lawn not taking for X reasons, normally it has got too dry for whatever reason. Check out the reasons why it has not taken and try to sort that.

    I'm inclined to agree with you Edd. March is rarely a good time for turf laying. image

  • I think it may be lack of water. We had a long dry spell here, before our recent rains. I did some small repairs about 8 weeks ago and they struggled too.

    hi folks, thanks for the replies. very much appreciated. We rotavated  all the area and took away around the top two inches of the soil. we then leveled all the remaining soil in the garden. i didn't use any fertilzer before we laid the turf, as i had laid my front garden last year and never had any problems. 

    i've never had a problem with drainage in my garden. I have a two year old and a 4 year old that sometimes would be out running around on the grass, could to much traffic be doing this to my lawn?

  • Hi all

    you can fertilise new turf, if you want. just make sure it gets watered in unless it is a liquid feed of course.Look for a high nitrogen feed on the pack it will state something like 15-5- 5 or whatever,the first number is nitrogen.If you can find it get it with humic acid  (potassium humate) apply and watch it green up.Be carfull to follow directions don't overapply.

    There has been a lot of fusarium about,but it is probably dry conditions that has caused the die out.Prick the patches with a fork leeving lots of little holes and sow seed into the holes.This way you can still cut and not disturb the emerging grass shoots.

  • I agree with Edd re less nitrogen use, your lawn needs more P and K.  You said you initially took away the top 2" of the soil ...  which is the top soil.  It seems what you were left with was sub soil and grass will never green up in inferior soil, no matter how much NPK you apply in future ... in one area of my garden the grass seeds were sown in sub soil and grass growth is poor ... 19 years later!
