Hello, I have just bought and potted two Bredon Springs Tree Mallows to keep on my patio. One is doing very well and seems happy with lots of healthy flowers. The other however, although covered in buds when I bought it does not seem very happy, flowers seem like they are trying to open but appear to be dying before they even get the chance. The rest of the plant looks healthy otherwise. I'm a pretty novice gardener so any suggestions as to why this plant in particular is so unwell would be greatly appreciated.
