Celosia cultivation and flowering control
Celosia is also known as red cockscomb, chicken cockroach, etc. It is named because its inflorescence is twisted and folded like a cock-crown. Annual herb, plant height 30-50 cm. Stems erect, flat above stem, green or red. Leaves alternate, ovate, ovate-lanceolate or lanceolate, apically fading, entire, stalked. The spikes are topped with a flat, fleshy, fleshy, chicken-like, yellow, white or reddish-purple flower with velvet sheen. Flowering from July to October. Oviform ovate, covered, containing 4 seeds. The seeds are black and shiny, with a grain weight of 0.85 grams. For flower beds, flower mirrors, and potted plants, cut flowers are also good, flowering time up to 10 days. There are four types of cockscombs, namely the hen's hen's crown, the common hen's hen, the broiler's crown and the phoenix's hen's crown. In addition, there are many varieties, divided by plant height, with dwarf species (20-30 cm), middle stem species (40-60 cm) and high stem species (above 60 cm); with flowering points, early flowers The difference between late flowers. The color is very pale yellow (near white) to golden brown, yellow, red, rose red, orange red to purple, and yellow and erythroid inclusions such as Sprinkle gold, two Joe and other complex colors. Celosia native to India. Hot and dry climate, afraid of earthworms, grows well in sunny, fertile sandy soils, avoids sticky soils, grows poorly in thin, airtight soils, and inflorescences become smaller. Can reproduce itself. Seeding and breeding, spring sowing in March and March in open field seedbed, sowing should not be covered with soil, cover grass after watering, keep the soil moist. After sprouting, remove the grass cover. It is transplanted when there are 2 leaves. Seedlings grow to 5-10 cm, ie, they are planted or on pots. It is not necessary to apply fertilizer at seedling stage. Otherwise, the growth of lateral branches will be strong and affect the development of the main branch. After the formation of the cockscomb, thin fertilizer can be applied to promote its growth. Seeds are easy to mutate and should be carefully selected each year. Celosia can adjust the flowering period by controlling the sowing date. Generally, sowing can be carried out from March to June. Sowing according to the needs of flowers can meet the needs of festival flowers.
