    Has the sunlight changed in this area? This can cause rolling of leaves. I really suspect a pH imbalance, though. This can be dealt with by adding dolomitic lime to the area. And if you suspect a fungal infection at all, then you will want to add wettable sulfur to the area as well. This will kill, and prevent any infection from starting.

    Yes, Phlox can do well in containers. They will need dividing in 2 to 3 years.

    Dead-heading phlox down to the basal leaves once all the bloom buds have opened. This will keep it from self-sowing everywhere but is a matter of personal preference, not plant health. Snapdragons often continue to make new flower buds on old flower stems so don't be eager to cut them down. Watch and maybe trim back that one cluster that is done blooming but only back to where it meets the flower stem. In fall let snapdragons go to seed and you will have more next year although flower color may change over time. Snapdragons are half-hardy which means they may live through winter. In the north, this is more likely if there is good snow cover. More on snapdragon care here: https://www.gardeningknowhow.com/ornamental/flowers/snapdragon/growing-snapdragon.htm

    Cut off spent flower clusters as soon as the flowers begin to wither with a pair of small shears. ...
    Cut off the entire flower spike once all the buds have bloomed and there are no new buds forming along the stem. ...this goes for both flowers!

    After a little research about the climate of that area of your country, it seems that your years are quite mild. You will be safe to plant now, and you can deadhead as the flowers die off. Phlox will tend to be quite invasive in mild climates, so make sure that whatever is nearby is at no risk of being taken over. As long as what is nearby is taller and more vigorous then there should be no problem.

    Your plant is phlox subulata, a creeping phlox that blooms in spring. Here is an article on growing it: https://www.gardeningknowhow.com/ornamental/groundcover/creeping-phlox/creeping-phlox-planting.htm

    When most of the leaves have fallen, cut the stalks down to 2-3 inches. If there was powdery mildew, remove fallen leaves as well. If you are asking about creeping phlox that has gotten too large or starting to be leafless in the center, wait until early spring. Cut an inch off the entire green portion or cut the green portion back by half.

    Thanks for your answer drtreelove, and yes silly me it was a typo, I mean Starfire Phlox! I agree with you, all the photos I can search for look exactly like the colour I’m looking for, yet all the descriptions say definitely red. So I just wondered if anyone has it growing in their garden so I can get a first hand idea of the colour!

    Stafford must be a typo, I don't find any variety of that name. But here are some more photos of Starfire:

    You be the judge, looks like somewhere between deep pink and cherry red to me. I haven't grown it to offer first hand positive color ID.
