Is it ok to cut the grass now? 27 degrees

[Guvner]

Will it damage the grass in any way? It needs a good cut but won't have any other time to get it done so want to do it now.

Side question of how to bring grass back to life that just looks a bit sorry for itself?

Can’t see why not? I made mine better by regularly feeding & putting down grass seed on the patchy bits

In the late afternoon/ early evening, fine but don't cut it too short!

Raise the cutting height to about 2" and it should be fine. Don't cut it again for a couple of weeks though.

My husband cuts it twice a week usually but avoids the hottest part of the day. Should be ok as long as you do that and keep it well watered. He's also scarified and loamed/overseeded it recently and it's definitely greened it up.

The only time not to cut grass is of wet. Not sure how temperature affects it. Mind you I don't have much green left in this heatwave!

I saw a garden designer saying not to cut the grass during a heatwave on instagram yesterday. Something about scalping it and being more likely to burn.

Don't cut it and don't water it. It will recover after the next shower of rain. If you water it you are encouraging the plants not to go looking for their own moisture and become dependent - so in the end they are worse off.

You can't kill grass off. In this weather, leave it be. Overcutting is, naturally, not great for it, and frankly grass being cut too often or watered all the time is a massive waste of resources (kinda like lawns in general, but I digress).

Don't cut it when it's hot and dry, it'll just dry out more. Grass doesn't grow much in these conditions anyway. Please don't water lawns - it's a monumental waste of water and the grass will be fine, it'll re-green as soon as it rains.

Advice is not to cut in very hot weather. I’m just outside London, we’ve had no appreciable rain for weeks, and none looks likely any time soon, so I’m not cutting.

As darlingdodo says, it’s a waste of water (water bill just increased!) to irrigate lawns too. They might look unsightly and brown now, but will green up very quickly once we get rain.

If it’s not too long then just leave it.

As an aside, IMO, it’s an extravagant waste to water a lawn. Grass does all of its “growing” below the soil. With our climate, watering a lawn is a huge waste of water. Sure, if we have a heatwave, the lawn might look rubbish for a few weeks. But, come autumn, it will revive itself without any help.
