Having created wildflower beds and meadows for clients, I've found the best way so far is clearing the ground in early spring with weed killer. After a week the weeds will have absorbed the weedkiller and I dig it over as preparing for a new lawn. Rake to a fine tilthe and then sow your preferred seed mix. Lightly raking the seed into the soil. A good watering and then let it get on with it.
This was done in a prepared bed and is still in flower now. It has already self seeded and will be cut in a few weeks time.
