The principle of fertilization is to apply the fertilizer with high nitrogen content at the seedling stage of Corydalis Africana. As it grows up, the fertilizer with balanced nitrogen, phosphorus and potassium should be applied. It should be noted that the smaller the seedling, the lighter the fertilizer.
