I would only do that in small sections at most. You can neither walk on a wildflower meadow, especially not barefoot, nor place a lounger there, etc.
Thank you for the objection. The mix will only grow 10-25 cm high. In this respect, it should basically work. We have initially planned this for the part of the property that is rather unused in this regard. So there should be no conflict between the meadow and the users. ;)
