    I would not divide them right now unless you can ensure that they will receive adequate water once replanted. It may be better to wait for spring instead, especially after winter or spring moisture has significantly penetrated the ground. This will also make it easier to dig up the plants. Doing so now in dry, hard soil will be more difficult for both you and the plant roots.

    Cut the Phlox back now and discard of the cuttings, don't compost these clippings.

    I then like to spray the area with a fungicide and again in the spring.

    It looks as if it might be garden phlox (Phlox paniculata).

    If you haven't been clipping the flower stems after the flowers fade, they could be dropping seeds. The seedlings generally won't look like the parent plant if the parent plant is a hybrid (which most garden varieties are). Here's an article that may help you: https://www.gardeningknowhow.com/ornamental/flowers/phlox/growing-garden-phlox.htm

    If the edges (or any other part) of the leaves aren't turning brown, it's probably nothing to worry about, but if the leaves are turning brown or have a white powdery substance on them, they may be suffering from not enough water or powdery mildew. Phlox also needs plenty of air circulation in order to thrive, so if the plant is overcrowded, that could be stressing it out and causing the leaves to react.

    There are a few possibilities. First, make sure you are watering regularly, but not during the heat of the day. Check whether the soil they are growing in is fertile enough; compost or other fertilizers could help if they haven't been added for a year or two. Also check whether any insects are present on the plants or if visible insect damage exists.
