Cultivation methods of Celosia
Sharing with everyone the content of growing Celosia at home, the cultivation methods of Celosia. If there are any mistakes, please feel free to correct them!
Celosia is named after its flower shape resembling a rooster's comb. Its growth habits include preference for warm and dry climates, fear of drought, love for sunlight, intolerance to waterlogging, but not strict soil requirements, generally suitable for planting in any soil in the garden.
Propagation and cultivation: Seed propagation method. Choose a good plot of land during Qingming, apply sufficient base fertilizer, till and level the soil, make ridges, and evenly sprinkle seeds on the ridge surface, slightly covering the seeds, pressing them down and watering thoroughly. Generally, at a temperature of 15-20°C, seeds can sprout in 10-15 days. Sow in summer after the Grain in Ear festival, taking advantage of dry weather to eliminate weeds, and it can also be intercropped with Bai Shao,牡丹 or other crops, using one jin of seeds per mu. When seedlings are 2 inches tall, thin them with a row spacing of 1 foot and a plant spacing of 8 inches. The thinned seedlings can be transplanted to other fields, and watering is essential after transplantation. It is important to weed and loosen the soil during the seedling stage, and water less when not too dry. When seedlings are about 1 foot tall, apply a top dressing once. After ridging, remove some old leaves appropriately. When flowering and heading, if the weather is dry, water appropriately, and prevent waterlogging in low-lying areas during the rainy season. After heading, remove the flower buds at the base of the lower leaves to allow nutrients to concentrate on the main spike growth.
Disease and pest control: If root rot occurs during the seedling stage, broadcast lime in the field. During the growing period, it is prone to small bridge bugs, which can be controlled by spraying carbaryl or pyrethroid pesticides on the leaves.
Harvesting and processing: Generally, before and after the White Dew festival, the seeds gradually turn black and mature, and the flower stems can be cut off in time and dried in a ventilated place to remove the seeds. Flowers and seeds should be managed separately and used as medicine separately. Generally, the yield is about 300 jin of seeds and 1000 jin of flowers per mu. When drying flowers, they should be taken out early and brought back late to avoid night dew, which may reduce the efficacy. Seeds should be cleaned and stored in bags to prevent mildew and insect infestation.
The above is a specific introduction to the cultivation methods of Celosia, hoping to bring some knowledge of flowers to flower enthusiasts.
