Hello.

I think I have scorched a patch of grass on my lawn, about a meter square.
(I left a piece of clear polythene there all day in the sunshine a few days
ago.)

Wil it recover alone, or do I need to re-seed it ?

I have been watering it well since I spotted it.


You are doing the right thing. Just keep watering it and it will
recover. As Charlie said reseeding will help if it's badly damaged,
but if the seed is not the same variety you may end up with an odd
patch.
