Advice on creating a wildflower border

I wonder if anyone could give me the benefit of their wisdom with regard to the pics attached. A children's nursery have asked me to do various bits of work in their garden that I’m fine with, but have also asked if I can create a wildflower mini-meadow around the border of their site.

It’s South and East facing but quite heavily shaded by the trees in the corner.

My main concern (apart from the shade) is the nettles and cleavers and what-not coming back through and strangling things.

Do you think the following would be ok?


Strim everything back
Dig the ground over
Obtain a mix of shade-tolerant wildflower seed with a good mix of yellow rattle and spread liberally

Or would should I be looking to put membrane down after strimming back, and planting in fresh soil on top of that? Or using weedkiller and covering the ground first for a few months to kill things off (I try to avoid using glyphosate/other weedkillers wherever possible)? Maybe bulbs would be better than wildflower seed?

Any thoughts and advice massively appreciated. And you can add a couple of extra pints to the tab of what I already owe you!


Thanks,

Andy
