While there's plenty of options to create your own fertilizer, keep the N-P-K ratio in mind. Nitrogen, phosphorous, and potassium are involved in healthy plant growth. Nitrogen helps the growth of stems and foliage, phosphorous maintains a healthy root system and flower production while potassium helps the plant's hardiness against insects and disease.
