How to cultivate Platycodon grandiflorum

Platycodon grandiflorum growing conditions

Platycodon should be planted on a slope with partial shade and partial sun, but it is best planted in neutral sandy loam rich in phosphorus and potassium. Platycodon likes sunlight, and the growing environment should have enough sunlight. It is drought-resistant and waterlogged, and attention should be paid to timely drainage.

How to grow Platycodon grandiflorum

Before and after Platycodon grandiflorum blooms, it should be properly shaded to prolong its flowering period. After the flowers fade, trim off the above-ground parts before winter to reduce nutrient consumption. Place it in a sunny and slightly warm place, and try not to frostbite the roots of Platycodon grandiflorum. The old roots will continue to sprout new branches next year.

Platycodon watering

In order to keep the planting environment of Platycodon grandiflorum moist, you can spray water through the air. Its daily growing environment should not be too dry. If the air is dry, its leaves will easily turn yellow and wither, affecting the healthy growth of the entire plant. If you water it too much, it will affect its flowering, and in severe cases it will cause its roots to rot.

Fertilization of Platycodon grandiflorum

Platycodon does not require too much fertilizer. It only needs to be top-dressed once every spring. When fertilizing, dig a small hole around the plant and bury the fertilizer. Keep the fertilizer away from the roots of the plant as much as possible. After the flowers fade, cut off the flower stems in time and apply bean cake liquid fertilizer to promote root growth.

Platycodon pest control

The common pest of Platycodon grandiflorum is root-knot nematode. If root-knot nematode is found, cake fertilizer can be buried in the soil to increase soil fertility, which can reduce the damage to a certain extent. If the pest is serious, it is recommended to remove the pot outdoors and replace it with new soil.

The main disease of Platycodon grandiflorum is anthracnose, which should be prevented in the seedling stage by spraying with a solution of fungicide every month. In the early stage of the disease, Bordeaux mixture can be sprayed once every 10 days, and sprayed continuously for 3 to 4 times.

How to grow Platycodon grandiflorum at home

1. Platycodon grandiflorum is suitable for growing in acidic soil. The soil for home cultivation can be mixed with sandy loam, leaf mold and garden soil. Bean cake powder can be added as base fertilizer to make the plant grow better.

2. Light is very important for Platycodon grandiflorum. Adequate light is conducive to its better growth. The suitable temperature for its growth is between 5℃-25℃.

3. Platycodon can be watered more often, but special attention should be paid to avoid water accumulation. It does not require much fertilizer, so a small amount of liquid fertilizer can be applied before flowering.

Platycodon grandiflorum care precautions

If you need to repot the Platycodon grandiflorum during its cultivation, stop watering 2 or 3 days before repotting. This will help the soil to separate from the pot. You can also cut off the part of the plant above the ground before winter to control the consumption of nutrients.
