To determine the soil texture for your Peach-leaved bellflower, you can perform a simple soil texture test. Take a small sample of soil, moisten it slightly, and try to form a ball. If the soil crumbles easily, it's sandy. If it holds its shape but feels gritty, it's loamy. If it feels sticky and forms a ribbon when pressed, it's clay. Adjusting the composition by adding sand, silt, or clay can help achieve the ideal loamy texture.
