How to grow Platycodon grandiflorum well

Platycodon grandiflorum growth conditions

Platycodon prefers warm and sunny environment, and is also tolerant to semi-shade. It can withstand temperatures as low as -20°C in winter. Platycodon is not very demanding on the soil and can adapt to most soil without causing poor growth. If the soil is deep and sandy and fertile, such conditions are most suitable for the growth of Platycodon.

How to grow Platycodon grandiflorum

In the process of growing Platycodon grandiflorum, sufficient base fertilizer should be applied before potting, and small amounts of fertilizer should be applied multiple times in the later stage. Fertilization should be combined with watering. Watering should be appropriate in spring and autumn, and can be watered every 4 to 5 days. Control watering in winter. In spring and autumn, it can be exposed to more sunlight, and shade is needed in summer.

Watering the Platycodon grandiflorum

Platycodon requires different amounts of watering in different seasons. In spring and autumn, watering should be appropriate, and you can water it every 4 to 5 days. In summer, water evaporates quickly, so you can water it every day. In winter, you can water it by observing the dryness and wetness of the soil. Generally, water it after the soil is completely dry.

Fertilization of Platycodon grandiflorum

Platycodon is mostly used for large-scale field planting, so fertilization is extremely critical. Sufficient base fertilizer should be applied in the early stage of planting, and urea or decomposed manure can be used for topdressing in the later stage. If the concentration of fertilizer is too high, the seedlings should be sprayed with clean water in time after topdressing. After each fertilization, the soil should be loosened in combination with watering.

Platycodon grandiflorum disease and insect pest control

Disease prevention is the most important thing in Platycodon care. Platycodon has delicate leaves and flowers and is most afraid of root rot, which is manifested by the appearance of black spots on the roots. As the disease spreads, large areas of black spots and death will eventually appear. You can use 1000 times diluted carbendazim to irrigate the diseased areas, and do not spray the medicine after rain.

How to grow Platycodon grandiflorum at home

During the maintenance of potted Platycodon grandiflorum, it is necessary to control the application of water and fertilizer to prevent the branches and leaves from growing too long and reduce the ornamental value. Apply 1-2 superphosphate before flowering. After flowering, provide shade to prolong the flowering period. After the flowers are finished, trim the remaining flowers and flower stems, and apply decomposed bean cake liquid fertilizer in time. Water once every 3-4 days in spring and autumn, water once in the evening in summer, and generally do not water in winter.

Platycodon grandiflorum maintenance precautions

Platycodon has a relatively high requirement for water. Too much water will cause problems with its root system, while too little water will lead to unfavorable growth of stems and leaves. It is best to water it by dripping, and it is best to water it thoroughly each time. Platycodon does not need to be watered within 3 days before repotting, so it is easier to remove from the pot.
