During the growing period, according to the weather conditions and soil moisture, supplement water, apply thin cake fertilizer or compound liquid fertilizer every 10-15 days, and plough and weed in time after watering and fertilizing each time. Fertilization should be stopped after pedicel sprouting to avoid bud and flower falling. After ten days of flowering, the remnant flower stems should be cut off in time to concentrate nutrients on the roots. The liquid fertilizer mentioned above should be applied again after flower withering and at the end of August to promote the growth and enrichment of rhizome, so as to facilitate the differentiation of flower bud and the growth of dormant bud.
