If that's anything other than something being poured or flushed from the other side of the fence then I'd eat my hat.

Could be accidental, have the neighbours been cleaning their patio recently?
^^
This.
I would wager that is Jeyes Fluid which your neighbour has used to clean his shed roof. Nothing will grow there and the only cure will be to replace the soil.

okay gents, the turf experts emailed me saying it is indeed, bad news "RED THREAD" frown

I've been recommonded to use some fungicide, and than I will dig the whole area and put a new roll turf..
Who told you that?

Now that I’ve seen more pictures, I’m even more convinced it’s not red thread. Red thread isn’t as devastating as that!

One of your pictures clearly shows a grass seedling with a pink colour to its top growth. That’s not red thread.

No chance. That's definitely not red thread.

The red/purple is typical of ryegrass basal leaf stems but yours are freakishly elongated. The pattern of affected grass and the mutant seedling development both scream contamination from something leaking onto your lawn from the corner, although I have no idea what it might be.
ooid, I’d wager that jagnet is more of an expert than whoever told you this is red thread. You’d do well to listen to his diagnosis instead of theirs.

My local turf specialists (rolawn) gave me the recommendation and diagnosis. I've sent them the same pictures.

I have another area now started to appear quite yellow-ish and similar look in the last 2 days? :/

We're gearing up for having a new lawn laid at the moment.

It did look like this:



Very uneven (where the dog had dug in the past), full of weeds but the robomower was keeping it looking very green. I had noticed a lot of brown spots appearing in a few places (urine related I think).

However it currently looks like:



The plan is to have all new turf laid as part of a bigger garden project.

What do I need to make sure the landscapers do? Obviously remove any rubble and ensure that there is a good amount of topsoil there (we're in quite a sandy area).

What should I do once it's laid? Water every day? Worth feeding it?

Do not, under any circumstances, let the idiots do what they did to mine, which is dump a load of sand (inches deep) over the rotovated clay for drainage. It means the grass needs constant care to look good - lots of watering, lots of fertilising, else it is stunted and weak.

Literally idiotic and back then I did not know to stop them. My grass is laid over pure sand. To remedy, I would have to start again.

I suspect that soil prep will be specific to what you have in your garden, but at least don't do the above.

Again that looks suspiciously like contamination running through from your neighbour.

What's on the other side of the fence? Some sort of patio cleaner maybe which has then been hosed off and spread under the fence?

After all the rain yesterday these have sprouted out of the lawn. It looks like a beetle shell on the end of the stalk. Never seen them before. Any idea what they are?

Something has been digging up my lawn, but I think it may be doing me a favour as I discovered one of these in one of the holes. Chafer grub?

A freshly laid green turf on the otherside. Again, I'm constantly checking 2-3 times a day my garden, so any contamination would have been noted by us easily. I gave it a mow tomorrow, it has been quite wet during the weekend. than will fertilize, and water twice. for the fukedup area, I'll just cut-out, aearate, put new top soil and lay a new rolled turf before september, that would be the ideal i guess.

I spread a box of Aftercut 3 day greenerama or something. It rained a lot afterwards which helped, but blimey the lawn has gone nuts and very green.

I suspect the Lawnsmith fertilised from a 3 weeks back also got properly digested.

If it's new turf nextdoor, is it possible that they have fertilized and it's running off into your garden causing fert burn as it's added to yours?

Ordered a 2 tons of fine topsoil and in the process of making a lawn level tool out of bits I have lying around.

Just want to fill in some undulations from when I laid the lawn last year, it has sunk in places where I added 18 inches of topsoil compared to other areas where I added barely any. It's also a couple of inches below the path which is annoying when mowing.

Anyone used a trommel or 'Rotary Sieve' to screen top-dressing?

Either a diy/cement mixer based system, or one of the Scheppach machines? Hired/made/whatever.

I have got about 5ton of nice loamy free-draining top soil which would be idea for dressing, but is currently 'as it came' from digging over an area of abandoned garden, so plenty of roots and rocks in it.

Hired a Scheppach. Very good and quick to get through a lot of soil.

A bit improvement, so to speak...





Scarified the dead turf and re-seeded with Fertilizer. Also used Provanto Lawn Disease Control.

Hi all, long time lurker on this thread. Lawn was seeded about a year ago, with a few inches of topsoil over very heavy clay. It was somewhat left to its own devices for the first year, and left far too long over the winter (probably 5 inches or so) before cutting in the spring.





Since then, it's pretty much looked like this every time I cut it. The grass that grows, grows strongly but there's a lot of dead grass in amongst, and it's very patchy. We're on the south coast so it's been very warm for a couple of months now, but I've been giving it a deep water each week if there's been no rain.

My thought is that it needs a really good rake / scarify and over seeding once it cools down a bit to pull out the dead grass. Does this seem about right?

A good rake might be all it wants, you can also top-dress to remove thatch if thats what you think it is.

Have you taken a core-sample of a bad bit, basically cut a square out with a spade to look at a cross section, actually quick and easy and basically non damaging.

One core sample (can you tell I'm not busy today?)



Doesn't really look like a layer of thatch so much as just some dead grass mixed in with green stuff to me.

Yes. Borrowed one from a neighbour. Does what it says on the tin.
