What type of wild flowers are you trying to grow?
Sowing seed into such a weed-ridden area is not going to be very successful, I'd pot grow and transplant when they're big enough to compete but annuals are usually best direct sown. Not and easy choice.
Annual weeds are best hand pulled or hoed before they seed. Deep rooted perennials, glyphosated. Don't cover glyphosated weeds.
