    I just googled that seed and apparently it is a mix of 3 types of perennial ryegrass, meant for sports pitches. ....
    That would explain why it has a slight resemblance to my son's team's football pitch ... on a good day :/

  • Can I ask how often you’re mowing the lawn when it’s growing at its fastest?  How long are you letting it get between mowings?
    About every 5 days I mow it.  I did take quite a bit off last time, I realise I should only do the top third or so.


  • it needs rolling, or just more foot traffic. Leaving it isn't going solve anything. 
    Your garden , your choice.
    I have a roller on my mower, is that sufficient? I also have a proper roller though, if I need to use that should I have using it heavy or keeping it pretty light? I use water to fill it.

    Maybe the word "Premiership" in the name of the seed should have been the giveaway... I'd suggest that whatever @Headshrinker99 does in the way of feeding, rolling etc, it will always be a lawn of coarse grass, which responds badly to close mowing.

    My other thought about types of turf used for sports pitches is that it is doesn’t ‘tiller’ as much as other types do because of the danger to players when slipping/skidding when wearing studs ... I may have understood this incorrectly but I think it’s how it was explained to me when being shown a newly seeded football pitch a few years ago ... 🤔

    I think the amount of moisture available is important too, I go to Capel Manor regularly and they keep some of their lawns very tightly mown but not all. I asked one of the senior gardeners about the lawn near the lake commenting that if I cut my grass that short at home it would be brown not lush green, his answer was simple "that piece of ground is always damp, if we cut the grass at the front of the old manor house that short (where it is drier) it would be brown too"

    Correction. Sorry, its the Platinum Pro seed that I used. Described as:

    Seed mix:

    20% Chewings Fescue (Musica)
    20% Chewings Fescue (Humboldt)
    20% Slender Creeping Red Fescue (Beudin)
    20% Slender Creeping Red Fescue (Cezanne)
    20% Strong Creeping Red Fescue (Rossinante)

    New and exclusive to A1LAWN. Platinum Pro is quite simply the finest lawn seed mix on the market. Blended using the best of the best in seed cultivars, nothing compares to its level of germination rates, colour, shoot density and disease resistance. If and when a grass seed cultivar achieves FERA certification it is placed in ranking order on the STRI index list and for certain seed strains (such as Perennial Ryegrass) this list can contain over a hundred cultivars. Every cultivar contained in our Platinum Pro mixes are at the very top of their respective categories. This is the first time such a mix has been available in the UK and we are very proud to be able to offer it to our customers.

    well there is nothing wrong with the seed cultivars but for Rossinante strong creeping fescue is a cheap filler variety which isn't great for cutting very short. The rest should be fine cut short easily shorter than what your lawn mower can cut at. 

    I looked at the post earlier today on the phone and I didn't think perennial rye grass was present with the needle like leaf which is fescue grass. New strains of dwarf perennials rye grass are very good and will tolerate mowing down to 4mm, more and more sports golf - tennis ( wimbledon 100% rye grass ) etc are using dwarf perennial rye grass , my own lawn is approx 60% Dwarf rye grass, I looked at the mix my self on ebay you've bought last year before seeding my own lawn but preferred the colour of rye grass and it harder wearing and the strong creeping fescue put me off. 

    Seen as you lawn is mostly fescue grass its very susceptible to red thread especially if the weather is warm and wet, the bottom picture the grass to the right looks like its had red thread,  to ID red thread it has a pinky ting on the tips of the leaf and then turns straw like colour over a few weeks. they no way of combating it other than giving the lawn a High nitrogen feed its getting late to be using nitrogen feeds so be quick . Red thread is a soil borne fungi.

    Another one for fescue grass it prefers Acidic soil , have you checked your PH of the soil. Iron sulphate will lower the PH  and toughen up the grass for winter. 

    How sharp are your blades on the mower ? its not tearing the grass is it ? 
     
    I be tempted to give it a light rake over in a few weeks time,  I wouldn't mulch personally but the left over cutting will feed the grass but possibly increase thatch levels.  

    If it were my lawn feed now  - light rake over in a 2-3weeks time then possible folk / hollow tine over and top dress with sandy top dressing if drainage is a problem or do it anyway it helps take nutrients / air down to the root system and helps with any compaction and other benefits - autumn feed mid october.  Raise the cutting height for now its to late in the season to cut grass very short its need to photosynthesis and take in as much energy as possible. 

    Having a top quality lawns is very hard work and very time consuming, I spend far to many hours and my own lawn and its half the size of yours . General rule shorter you mow more work is involved 

  • Thank you all so much for your advice. 

    I've cut it today, brand new mower and at its highest cut setting. I've also fed it, rolled and watered it. In October, I'll aerate it and feed it again with an autumn fertiliser. I'll keep it at this height until next spring when I'll investigate a shorter cut again. Though I'm liking how it looks now :-)
