Newly laid turf 6 weeks down - what next?

Folks, I had previously posted on here about drainage issues in a new build garden. Long story short, builder got a landscaper to come out and put rolls of turf down 6 weeks ago. They also inserted a new pipe under the lawn, added some rocks and then a layer of sand before putting the rolls of turf on top. No new topsoil was used.

6 weeks down now, and after 3 weeks I cut it and have cut it at the highest setting on the mower which is 2.4 inches in height weekly since.

Noticed a few bare patches where the turf either didn’t join together or presumably something else at play. Also noticed a bit of moss already in these patches - I am based in Ireland so it is a damp climate tbf.

I reached out to the company where the landscaper bought the turf and I was able to buy the same grass seed off them. There has been very few weeds so far, and I asked them what has they sprayed on the turf rolls and they mentioned something called Pastor Trio.

Having had a weed, clover, moss and creeping buttercup lawn in the same garden before they addressed the drainage, I am happy that I don’t want that garden again and I can see from my neighbours that there garden has been completely taken over by all of the aforementioned. I’m not looking for a bowling green either but would like to keep the lawn along the lines of how it is now - weed free and a somewhat decent layer of grass.

So my questions now are after 6 weeks in:
1. Where there are patches should I put some seed down? If so, what should I be using as a layer for seed to germinate in? Topsoil, compost or something else? As the garden is small I will end up buying whatever is suggested from a generic gardening/DIY store so not sure how good or screened the quality will be.

2. Should I be putting something else down first - like a lawn feed, weed and moss killer? If so any recommended brands?

3. Is there anything else I should be doing or looking to do in the next 6 weeks.

Thank you

 

It looks to be a satisfactory turfing. PasTor trio is a selective weedkiller for pasture which kills broadleaf plants. it is for qualified use only. It should not need retreatment unless/until new weeds are introduced.
If it were mine I would:
keep off it when its wet.
mow lightly but regularly.
water in deficit ,if permitted
review in early Spring after second mowing
(construct a path to shed from right to left ...)

 

Thanks @infradig
I had never heard of PasTor Trio before but was wondering what they had used due to the fact the turf was relatively weed free.
I have been keeping off the lawn when wet and in general tbh
I have been mowing once a week or maybe even every 6 days
Watered during the hot spell we had last week

So you think there is no need to add any summer fertiliser type to the lawn at this stage purely from a feed perspective?
Good point on a path from right to left to the shed, something I will look into.
For the area to the right side of the shed, well halfway down the shed to the back fence I plan to put in a flowerbed/plants of some sort.

 

It seems to be green (enough) and its growing (because you find cause to mow it ). If it loses either characteristic , which it won't yet if your landscaper has done his job, then review it. Presuming your cattle are fed elsewhere, then what more will you achieve ?
Because grass self sustains, its only the effect of removing the cuttings from the site that will need assistance in due course.
Grazing animals would recycle ;its the carbon cycle.
However you can do their job (so to speak !) by top dressing with a natural alternative in the future.I would personally avoid proprietary product and use organic material.
A substitute might be small quantities Vitax q4 or chicken pellets ; you only need to maintain fertility as it is an amenity not a production space. Consider other users(dogs/kids ?) if applying anything, especially if chemical based.
