Hey Guys,

Need some help to see what to do with this grass I'm devastated.

A few weeks ago some patches started to go yellow I I brought some hose on insecticide,wetting agent and fertilizer it's was a 3 in 1 hose on pack.

Now about a week and a half later this is how it looks. I check the product I used and it doesn't say anywhere it's not safe for the grass I have.

Any help would be much appreciated.

Cheers Ben

What was your soil prep like before you laid the turf, not straight over the top of what the builder left behind I hope? How often have you been watering it?

Such grass looks dry, there is definitely no water. The preparation intended for nutrition shouldnt corrode drying, I think there were other destructive factors.

If you've watered it and it's still on coming good than its likely you got grubs mate.

I cooied and pasted this advice from my response in another forum...

Hit your lawn with a bag of Scott's - lawn builder, grub and insect (red bag) from Bunnings.

It's got Bifenthrin as the active ingredient which will knock out the active grubs and fertilise your lawn. I don't suggest using it regularly as it's fatal for bees and a little nasty.

After 3 months i suggest buying a bag of Acelepryn and applying it every 3-6 months. It has Chlorantraniliprole which is more selective and will not harm bees etc. It is effective on grubs bit more so the grub eggs.

With water and the fertiliser it should keep your yard looking good

Hmm, as another option - it could be the damage from the product. If your lawn wasn't watered enough, then it could burn from the sun.You can install oscillating sprinkler, for instance, and use it in the morning/evening when watering applies best. My neighbors and me use Rainbird since it's quite easy to install. Plus they have good controllers and good pop ups (not affiliated with them, just talking from my experience). Others will do just the same (but my personal recommendation would be copper or at least aluminium ones, plastic ones are not reliable).

But I agree with Rhetti, if it turns yellow, then dies so quickly, it could be grubs. They destroy the root system underneath, then the grass turns yellow and dies. Quite easy to check - dead grass will lift up like a carpet because the root system is gone. From experience you will need to treat at least twice for a bad infestation.

(if the "texture" looks like this, then it's certainly grubs)
Hope you'll be able to revive it. Good luck!
