Grass all of a sudden yellow

[purpleme12]

Can this happen by pouring weedkiller on the grass??
It's just today is gone yellow

What weedkiller did you use, did you pour it all over the lawn.

It's ok I know what's happened
Same thing happened last year
Only this time they've decided to ruin almost the whole of the grass rather than a few patches 😓

Oh dear, whats happened.

Neighbour damaging our garden amongst many other things they've done/doing

Thats awful, have you got any evidence, have they poured too strong weedkiller on and burnt it.

Yes it's on purpose they've done it before but this it's almost the whole lawn
But no I've no proof
But I know it's them cos of all the things they've done/doing
I'm so sad

You need a camera.

Yes you need a camera and anything else to gather evidence of whatever they are doing, are the police involved.

Yes I keep getting let down by people about fitting it
I guess I'll have call a handyman
However I've seen how he does it to his driveway
He has this spray so he might not have been in our garden to do it. If that's the case he wouldn't be caught on camera ☹️

Yes police are involved
Although it doesn't stop them

Is it the front lawn, ask for a local handyman to help you put up a security camera, a ring doorbell and you can get cameras for inside the house linked to your computer and phone. Have the police given you any advise.

Yes the front garden where everyone can see it
I've put the biggest fence I can up in the back garden (losing some of my garden in the process but it's worth it) although he could still spray over if he wanted
The only advice is cameras and evidence
And we don't have enough evidence 😓

I'm not a garden person
But it was absolutely fine I've got pictures there weren't overgrown weeds
And now it's completely ruined

I am no expert, someone else here will come along with good advice but it might grow back, can you hose it down with water to dilute the weedkiller. Do try and get cameras put up front and back if he is causing problems. Would any other neighbours have seen what happened.

Unfortunately the patches he decided to do last summer have completely died now. Worse than yellow, just no grass.
So I doubt it will grow back 😓

Is it true that you have to dig up the actual soil where it's died and then plant grass seed?

I'm just so sad now
It's completely ruined 😓

I wonder if anyone at the council or environmental health can advise you, if you think the grass has been contaminated with something and smells very toxic they might be able to do soil samples and find out what killed it. It may have caused damage to the insects, birds, animals that walk across it. Is it a big lawn, would you be better having the grass taken up and replaced with some nice gravel.

Something that kills grass over the longer term may not be a weedkiller. It may be a soil contaminant. I use turf chemicals reasonably regularly and don't know of any that have a longer effect than 3-5 months.
If there is nothing growing in the areas killed last year, I'd suggest diesel or something similar was used. This will need to be dug out, disposed of correctly, and replaced. There are some products which will degrade oils safely (using microbes basically eat the hydrocarbons) but I'm not sure of price I'm afraid.

😓
If all the things they've done I'm most sad about this
I'm not a garden person, I don't know what to do about these things and don't have confidence to do these things
The grass was fine before 😓

Ok, you need help sorting this out. Look on your local community fb page and see if there is a gardener who can come and take a look. If it happened that suddenly then theres no point in planting new grass if the soil is contaminated you need to find out if it was chemicals or diesel like pp said. I would also call environmental health for their advice qnd let the police know as you have had problems before.
