    All of that was planted, but all of that is highly invasive. You will have to scorch that portion of garden plot. Either with fire, or boiling water. Even chemicals can help, but there are less harmful ways. Dig up everything then pour boiling water over it again. It will still try to come back but you will be able to control it easier at that point.

    You may try using a broadleaf herbicide, as these tend to leave grass intact. You can find more information here: https://extension.umd.edu/hgic/faqs-lawns-weed-management-summer

    It depends on the product, but 10 -20 pounds per 1000 sq feet is standard.

    At 20lbs/1000 you would need 880 lbs to cover an acre.

    Oh boy... Even when used properly, the half life of this product is 30 to 60 days. It could be up to two months before the ground is suitable. This is a selective herbicide, that doesn't usually effect grass. Under no circumstances should it kill grass unless it is used way out of proportion to the label.

    Follow all instructions on the packaging when it comes to toxic chemicals such as this, since they are likely to cause issues with runoff in groundwater, and getting into sewer systems.

    In the US, these particles can be found in our water supply on occasion, signaling that it does not get destroyed completely by chemical or filtration systems.

    Please take care in following all instructions on the label when using dangerous chemicals, and hopefully you can reseed in a month or two.

    I'd say that right now is your perfect window for applying pre-emergents! The clay doesn't, necessarily, contribute to weeds, but it doesn't help things out either.

    There are ways to amend the clay soil to help it to be better suited for planting, though. This article will help: https://www.gardeningknowhow.com/garden-how-to/soil-fertilizers/how-to-improve-clay-soil.htm
