When is the best time to sow Platycodon grandiflorum?

Platycodon grandiflorum sowing time

Platycodon is a perennial plant of the Campanulaceae family. It mainly reproduces and spreads through seeds. It usually blooms about three months after sowing. The flowering season is from July to September, and seeds will be produced at the end of the flowering season.

Platycodon is suitable for sowing in spring, and the best sowing time is in mid-to-late April. At this time, the temperature has risen to around 20 degrees Celsius and precipitation has begun to increase, which is very suitable for the growth of young shoots after seed germination. After a few months, they can grow into mature plants.

Platycodon grandiflorum sowing method

1. Soak

After the Platycodon grandiflorum seeds are harvested, in order to preserve the internal activity for a long time, they will begin to enter a dormant state. At this time, it is necessary to soak them for a period of time to wake up the seeds.

2. Planting

The next step is to bury the processed seeds in the soil, and then pour in a certain amount of clean water to make the soil moist, which will facilitate the germination of the seeds and the growth of the young shoots.

Key points and techniques for planting Platycodon grandiflorum

1. Lighting

The amount of light that Platycodon requires during its early growth period is moderate, but care must be taken to block strong light, which can easily burn the branches and leaves of new plants and cause damage.

2. Moisture

During the growth process of Platycodon, daily rainfall can meet its water needs and does not require additional watering. Excessive watering will cause the soil to be too wet and the roots of the plant to rot.
