you should cut a wildflower meadow in late august/early September (right after the kids go back to school is perfect) wait until a dry week as you want the cuttings to lay in the sun for a couple of days as this allows the seed to drop.
it needs to be cut about 2 to 3 inches tall and then as much raked off as possible, you want little to no nutrients going back into the soil as it encourages grass/nettles/brambles to take root.
I would also add some yellow rattle seed as this is a parasite of grass and will weaken it, allowing the wildflowers to thrive.
you can cut is with a scythe (if you want your back to ache) a strimmer (as long as you don't much up what you cut - as its a nightmare to rake off afterwards)
but the easiest way is a powered allen scythe - maybe the council will hire you one as you've taken over the maintainance of the area? round here its about £85 a day to hire or £120 for a whole weekend. you can even get a small bailer attachment.
