Young shoots of a plant are covered to exclude light to prevent photosynthesis and the production of chlorophyll, and thus remain pale in color. Different methods used include covering with soil (hilling or earthing up) or with solid materials such as board or terracotta pots, or growing the crop indoors in darkened conditions. Refer to — blanch a plant. I have used the leaves such as on cauliflower or dirt or paper from a shopping bag to cover the area.
