New seeded lawn

stuarta99 · May 2020

So I've seeded my lawn after renovating the ground and it's been 4 weeks today. I applied starter fertiliser and it seems to have done well. As you can see from the pics there are some patches, mainly around the edges which I'll need to top up but I'm thinking it might need a trim first?

I've seen some people say 5cms and some say 7cm. It's currently averaging 10cm although some newer bits still possibly coming up. As much as I want to trim it to reseed the patches and worried it is getting long, obviously don't wanna screw it up.

Just cut on the highest setting, and then do that a couple of times before lowering it, and if it's very hot/dry by that time where you are, keep it longer again.

Always better to do little and often with grass. It's only just getting going, so don't cut it short whatever you do.

Ok thanks, I normally cut on highest anyway and I think my mower is 60 which I presume is 60mm.

So safe to do it now then before I patch?

I'd give it a light trim, based on your pic, then leave it to see how it goes re weather etc

Ok thanks, will go over at the 60 and then patch the bare bits. I'm pleased how it's grown, just hope it makes it through the winter but hopefully being lined with plastic bags didn't help

It's grass - winter doesn't kill it

I take it there aren't any plastic bags now though, and there's proper drainage? If not then, it mightnot survive winter!

Nope all the bags out and removed lots of leatherjackets. Spoke to grass people who treated it and said how their 'experimental' treatment didn't work because apparently the normal has been banned. They did say they'd had mix results but have a better one now. I'm going to apply more nematodes in Sept as a precaution.

As I water with the hose it puddles slightly but goes away, I've done the best I can for now.

Trimmed it and it's a bit flat from where I walked on it but I'm pleased for just 4 weeks. Feels more luscious as well and is supposed to be hard wearing so hopefully that will help as well.

That's the only problem with cutting quite early on, but it should toughen up over time.

Give it another cut in a week or two [just depending on your weather and the amount of growth ] and then it should settle a bit, and you can probably cut it a little shorter. if you have long dry spells though, it's always better to keep it on the longer side though.
In the meantime you can resow the little bare sections

Yeah I've reseeded patches and the edges which I didn't do well. I did dress most the patches with the same multi-purpose compost I had but ran out so had to do some with Ericaceous, I couldn't remember if it was ok to use that but thought it's only a light dressing.

Is it ok to cut again before the new seed that I've planted grows?

Fairygirl · May 2020

I think it would be ok @stuarta99 - try and avoid trampling too much on the re seeded bits if you can.
You could wait, but you'd either have to wait until autumn to resow, when growth slows a bit, or not cut for ages.

If you tread carefully when cutting, it will actually just ensure the seed is in good contact with the soil, which is what you want anyway

The compost you've used won't really matter either .

Ok great thanks. I guess cutting it at 60mm it's got to grow a bit anyway until the mower blades will touch it. The main bits I've seeded is all the edges so can keep away then just the odd patch in the middle.

Looking better stood up today
