First, the breeding method. Celosia seed breeding, can be long-term seeding multi-season flowers. Spring mid-April to early June can be broadcast on the open field seedbed at any time, such as in order to ensure the “51” flowering or late summer flowering, can be sowed in mid-November until before the Spring Festival greenhouse, germination appropriate temperature is about 21 ℃. Sowing requires careful preparation, mixed sand planting, overlying thin soil. Seedlings grow to 2 to 3 true leaves, 5 cm high when the seedlings, plant spacing are 5 cm, seedlings grow to about 8 cm when transplanting, plant spacing of not less than 15 cm, spacing 20 cm, for dwarf varieties , After removing the pinch to make it more
