1. Plant introduction

Platycodon grandiflorum is a perennial herb of the genus Platycodon in the family Campanulaceae. Its height ranges from 20 to 120 cm, with a hairless surface and almost no branches, except for a few at the top. The leaves are arranged in whorls or alternately, with very short petioles or even no petioles, and are oval in shape. The flowers are generally terminal, with several flowers arranged in racemes, and are mostly blue, purple or white. It blooms from July to September every year and then produces spherical capsules.

2. Growth habits

Platycodon grandiflorum likes a cool climate, has strong cold resistance, and likes light. It is more common in hills below 1,100 meters above sea level. Its seed lifespan is about 1 year, and can be further extended if the temperature is low. Moreover, low temperature helps to increase its germination rate, which is generally around 70%. If the temperature is suitable, seedlings will emerge in about 15 days.

3. Maintenance methods

1. Soil: Platycodon grandiflorum grows well in sandy soil. Good drainage can prevent the roots from being flooded. Adding a certain amount of phosphorus and potassium fertilizers to the soil as base fertilizer will help the development of the plant.

2. Light: Platycodon grandiflorum likes light, so it should be planted in a sunny place. Indoor potted plants should be placed on the balcony to allow them to receive sufficient light. If the environment is dark, the plant will easily grow too tall, affecting its flowering.

3. Watering: Platycodon is very afraid of waterlogging, so do not water it too much. Generally, in spring and autumn, watering once every 3-4 days is sufficient, and in summer you can water it once every 1-2 days. Keep dry in winter. If it is rainy, drainage should be done well.

4. Fertilization: During the flowering period of Platycodon, appropriate fertilizer is needed. Because its flowering period is very long, it needs to be replenished with nutrients in time, otherwise it will easily wither prematurely, affecting its ornamental value. In addition, adequate fertilization also helps the development of fruits.
