Platycodon grandiflorus Fuji White Seeds - Ballon flower

Sow Platycodon grandiflorius Fuji White from February to June, in a seed tray. Use good quality soil that you will sift on the surface in order to bind the seed to the growing medium. Before sowing, lightly tamp the soil down with a small board of wood. Broadcast your seeds. Cover the seeds by sprinkling soil or vermiculite over them. Tamp down lightly and water generously with a fine spray. Place your seed tray in a bright location without direct sunlight, at a temperature of 18 °C to 20°c. Lower the temperature at night to 16° creating a temperature variation beneficial for germination.

Germination will take 14 to 30 days. As soon as the seedlings can be handled, transplant them into 7 cm pots. Keep the soil moist, but not wet during growth. Then, 15 days before planting them out in their final position, start to acclimatize them gradually to a temperature of 15 °C.

At the end of May, beginning of June, temperatures in the garden will be warm enough to plant out your young plants. Choose a site with plenty of sunshine. Add a good shovelful of compost to each planting hole. Space your plants 30 cm apart.

Regularly remove faded flowers to keep the plant tidy-looking and encourage flower renewal.
