Advice? 6 wks after lawn burnt using 4 in 1

I posted a while ago that I applied evergreen 4 in 1 but unfortunately it’s burnt the grass - a common mishap. It’s 6 weeks since and while there is growth in parts the burnt area is showing no signs of recovery. Any advice on next steps?

My thought was to mow now on a high setting to keep the long grass under control, and then to reseed in 2 weeks time - giving it the full 8 weeks before doing so as evergreen recommends. This would mean reseeding in mid June. Or am I now better leaving it and doing this all in late summer, say mid sept early Oct?

 

I wouldn't reseed in the middle of the summer better to wait till Autumn also I would scarifie the lawn first.

I bought one of these a few years ago and it is great for getting all the thatch and dead stuff off the lawn.

Hi

Yes wait till later in the year is best , still looks like too much was used as you can see the lines as it was applied

 

Yep, I scarified after 2 weeks so hence looking a bit bare. I’ll mow the longer stuff as and when but will leave the reseeding till later in the summer/autumn. I’m presuming mid sept to mid Oct is the window I’m looking at for this, when there is a greater chance of rainfall helping things along?

 

And is there anything else I should be doing now to help the grass recover?

 

Just keep mowing for as long as it keeps growing, little but often which encourages it to branch and helps to discourage it from making flowering stalks (a stressed plant's natural reaction is often to run to seed). Wet weather will help it but can't be guaranteed.

If weeds start to appear, either hand-weed or spot-treat them with a lawn weedkiller spray. No more feed & weed (or feed of any sort) until the grass is recovered - maybe an autumn lawn food later in the year if you can find one without weed/mosskiller in it, and if you can time it to fit in with the reseeding. Otherwise leave off feeding until next spring.

 

You can certainly reseed at this time of year if you're in a reliably damper part of the country. The new lawn I created about 10 years ago was done in mid June.
However, if you don't get decent rainfall where you are over the summer, [which will help enormously] you may have to wait until early autumn for any reseeding, because otherwise it would mean good, persistent watering, and IMO, it's a serious waste of resources, especially in those areas which have water shortages through summer.
It will recover though, and cutting as @JennyJB describes, will also help. Avoid going on the bare bits too often if you can. It can be difficult to avoid over application sometimes, but the grass will gradually come back once conditions suit it.
It looks like quite a shady site too, so if you reseed [and you can do the whole area later] it might be worth looking at a type of seed that will suit a shadier site. What you do also depends on how fussy you are about a perfect lawn or just having something reasonably green.

 

Thanks everyone for your advice, really helpful!
