Cockscomb flower doesn't have to be very good, just planted in the soil.
Plant two to four shoots in the spring. When planting Cockscomb flower, it should be slightly deep planting, leaving only cotyledon on the soil, and make pot soil slightly dry, induce inflorescence to appear at an early date. After inflorescence, change to a 16 cm pot. Before turning over the pot, water should be poured. If you want to get large flower heads, you can change the 23cm pot again. At the same time, pay attention to the matching pot. Small potted low - growing species, large potted high - growing species such as phoenix tail and cock crown. For low and much branched varieties, the heart should be picked after colonization to promote branching. Erect, branching varieties do not have to pick the heart.
Cockscomb flower likes warm, don't cold. Get plenty of light during the growing season, at least four hours a day. The suitable growth temperature is 18-28 ℃. When the temperature is low, the growth is slow, and the planting forest dies after winter.
The basin soil for Cockscomb flower should be fertile, with fertile loam and cooked manure mixed in half. During the growth period must be properly watered, but the basin soil should not be too wet, moist and dry is appropriate. Prevent barren or late flowering. Growth later add phosphate fertilizer, and see more sunshine, can promote the growth of robust and large inflorescence. In the mature stage of the Cockscomb flower seed should be watered less fertilizer water, to facilitate the seed mature, and make a longer time to maintain the color of colorful.
Cockscomb flowers are sown and propagated in spring when the temperature is between 20 and 25 degrees Celsius. Before sowing, some cake fertilizer or barnyard manure and compost can be applied in the seedbed. Sowing should be done with some fine soil in the seeds. Because cockscomb flower seeds are small, cover them with 2-3 mm of soil, not deep. Before sowing, the soil in the seedbed should be kept moist. After sowing, a fine eye watering can be used to spray a little water, and then shade the seedbed. Do not water it for two weeks. Generally 7-10 days can emerge seedlings, seedlings to grow 3-4 pieces of true leaves can be thinned once, pull out some weak seedlings, too dense seedlings, seedlings to 5-6 cm high when the root soil should be transplanted and transplanted.
The disease mostly occurs on the leaves of the lower part of the Cockscomb flower. The pathogen is a fungus of the subphylum falcifolia. The mycelia and spores overwinter in the plant residues and soil, and are spread by means of wind and rain, irrigation, and splashing water.
1. At the beginning of the disease spot is a small brown spot, after the expansion of the disease spot is round to oval, dark brown to purplish brown edge, the inside is grayish brown to gray white.
2. In humid weather conditions, pink mildewy matter, i.e. conidia of pathogenic bacteria, appears on the plaque.
3. In the late stage of disease leaf wilting or spots dry warm I fall off, resulting in perforation.
1. Remove diseased leaves of Cockscomb flower in time.
2. At the early stage of the disease (disease spots appear on the lower leaves of the Cockscomb flower), use 0.2 ~ 0.5% potassium permanganate solution; Or 50% methyl tobujin wettable powder 1000 times liquid; Or 50% denonium wettable powder 500 times liquid spray prevention.
3. Avoid continuous cropping in affected areas. It is better to rotate with other plants or crops at intervals of 2-3 years.
Cockscomb flower species can be divided into broomstick comb, face comb, mandarin duck comb, tasseled comb and so on, depending on the morphology of inflorescence.
Harvest the autumn flowers when they are in full bloom and dry them in the sun.

2. The feathery flower: the flower shape is feathery, the corolla is flame like, the color is bright, whether the flower bed cultivation or does the cut flower, is very pleasing.
3. Lance type: the corolla resembles the conical shape of fir tree, the spikelet is short and tight, there are particularly suitable for cutting flowers of the high species and suitable for flower beds of the vigorous species.

Cockscomb flower has good resistance to sulfur dioxide and hydrogen chloride, and can play a multiple role in greening, beautifying and purifying the environment. Cockscomb flower is suitable for plant and mine greening, and can be regarded as a public ornamental flower against pollution of the environment. High stem species can be used for flower border, embellish the outer edge of trees, as cut flowers, dried flowers, etc. Cockscomb flower (C. Kristasta var, Pyramidalis), native to India, with erect, branched stems and spikes.It is also widely used.
