If the grass is growing well, it's probably too rich.
I converted my front grass, which has never been fed by me in 25+ years.
The first year I cleared small patches and sowed wildflower seeds. None of them came up. I let the grass grow and just mowed a path through. The marguerites, selfheal and other sturdy wild plants as well as a variety of grasses looked very nice. I bought a few perennial wildflowers and planted a patch of Greater Knapweed, another patch of Night Scented Catchfly and another of Sneezewort. Also individual plugs of yellow rattle here and there.
This year I added annuals again but more carefully! Along one side there was a shady patch which had had bits and pieces dumped on it. Took away the rubbish and had bare soil with no grass growing. The annual seeds I put there gave a lovely show this year. Cornflower, corn cockle, corn marigold and poppies. I had to weed around them when they were coming up otherwise the more vigorous established wildflowers would have taken over.
