Not sure I should really be giving advice on this - as I have been trying to create a flower meadow (with not much success) for the last 5 years. However, the one thing I have learnt during my efforts is the importance of yellow rattle - its a plant that's parasitic on grass so keeps the grass down and gives the flowers a chance to grow. In the patches where I have got YR going I am having much more success.
I bought my YR seed last autumn and sowed in patches straight into the ground. It needs to get good and cold before it germinates, so needs a winter exposure.
Good luck with it
