My impatiens plants leaves are yellowing. Seems to be dying although there are some small green leaves growing at the base of the plants.

There is a serious impatiens threat from what is called impatiens downy mildew, Plasmopara obducens. Other possibilities are nematodes, botrytis blight and verticillium wilt. All of these require removal of the soil to prevent spread to other plants and do not plant impatiens for the next few years. Here are details on impatiens downy mildew: https://www.extension.umn.edu/garden/yard-garden/flowers/managing-impatiens-downy-mildew-in-landscape/
