    I do believe the closed dark purple ones look to be spent blossoms.

    If you look closely you should see the edges appearing drier than say new budding flowers.
    If you leave them to fall off themselves they usually leave the stamen behind. You can then pinch that part off of the plant.
    I like to use a small garden snip and trim them back to the next group of flowers.

    Enjoy!

    We normally recommend using Neem oil for most insect pests in the garden. It is both safe and effective, and as a bonus doubles as a fungicide too. Here is more information: https://www.gardeningknowhow.com/problems/pests/neem-oil-uses.htm

    I'm not sure of the cause, but sometimes our plants need a little help!

    I would clean them up with a quick dead head and see how they act the remainder of the summer.

    Petunias are usually pest free for the most part; however aphids and cutworms occasionally affect these plants. In this case, it sounds like cutworms may be the culprit, as they typically 'cut' the plants as you describe.

    It sounds like it may have a fungus. Trim away any yellow or brown growth and then treat the plant with a fungicide.
