Soil requirements of Platycodon grandiflorum

Before applying fertilizer, we need to know what requirements they have for nutrients in the soil. This kind of plant needs more fertilizer. Therefore, in the process of its growth, we should not only maintain the integrity of various components, but also ensure that there is more calcium in the soil. In other words, this plant also has requirements for the soil itself. According to the experiment, the soil with pH between 6 and 7 is better for this plant

Key points of using fertilizer

Fertilizer is generally 14-0-14. Fertilizer can be applied only after the leaves of Platycodon grandiflorum stretch out. Watering in the morning can be carried out alternately with fertilization, and the frequency is once or twice a week. It should be noted that it is important to pay attention to its concentration

Precautions for fertilization of Platycodon grandiflorum

1. If there is less base fertilizer at the beginning, it is necessary to topcoat. When topdressing, we must follow the key of "a small amount and many times", and we must not topcoat too much at one time

2. Make up for what you lack. Maintaining balance among nutrients is the key to plant growth and even income increase

3. During the growth of Platycodon grandiflorum, ventilation, dryness and sufficient light must be ensured. But when the temperature is too high, you should still pay attention to shading

4. Although ammonium nitrogen can effectively promote the growth of stems and leaves, if it is applied excessively, it will lead to large and soft leaves, which are not easy to survive, and even make them grow in vain, especially when the temperature is not high

5. As mentioned before, Platycodon grandiflorum also has a great demand for calcium. If the leaves turn yellow or wither during the seed process, it is a manifestation of calcium deficiency

6. If the stem is too fragile and easy to break after the plant is formed, or the stem is longitudinally cracked, it may be caused by the lack of Peng
