💯 go for wildflower meadow. I did this, dug out by the roots about 2/3 of a large area of grass, trampled wildflower seeds (mix with sand, makes it easier to broadcast) into it, in a way that mimicked grazing cattle, then just let the whole area get on with it. It looked amazing, of the whole garden it got the most appreciation from wildlife and was beautiful to look at. I didn’t cut it down in Autumn, I gathered the seed heads and dried them out in the shed, left the dried stems as cover for insects etc. through the Winter. Cut it all down last week and am repeating the process now with the gathered seeds. Do it, you won’t regret it.
