1、 Breeding environment

1. Fertilization: it needs to be fertilized at least three times a year for its growth. After germination for the first time, it can promote colorful flowers and flower bud differentiation. The second time after flowering is used to supplement nutrition and promote seed development. The third time is from September to October, which can promote the growth of underground stems. Potassium fertilizer and phosphorus fertilizer are the main fertilizer for each fertilization. Pay attention to stop fertilizing when it is hot in summer

2. Watering: it likes a humid environment, so it should be watered more. During the peak growing season in spring, increase the amount of water; In summer, the temperature is high and the transpiration is strong. Watering should be sufficient, preferably in the morning or evening. It is better to reduce watering from late autumn to winter and the soil is slightly dry

3. Light: in early spring, we should maintain sufficient light to be more conducive to flowering. The sun is strong in summer, so it is necessary to shade properly and spray more water to avoid leaf burns

2、 Weed control

During the growth of iron chopsticks, we should also pay attention to weeding in time. In general, weeding should be done 5-6 times in a growing season. It is best to wait for the soil to dry a little after each watering or rainfall
