The invention relates to a natural dyeing auxiliary agent for dyeing middle and light color systems and a dyeing method of the natural dyeing auxiliary agent. The natural dyeing auxiliary agent consists of, by weight, 90-60 parts of apple pomace liquid fermentation aqueous solution, 0.5-3 parts of B vitamins, 3-0.5 parts of sodium polyaspartate, 0-2 parts of light rare earth EU<3+> or La<3+> and 6.5-34.5 parts of purified water. A composite dyeing mode of one-bath dyeing promotion and after-bath mordant dyeing is adopted. Compared with the prior art, the natural dyeing auxiliary agent has thebeneficial effects that the color systems formed by plant dyeing, such as gray, purple, yellow green and brown, are firm in color fastness after subjected to soaping, dry-wet friction, light resistance and the like, the color fastness is improved by 1-2 levels, and the actual requirement of industrial mass production is met.
