The reproduction and management of Crabonia

C. jasminensis is native to Brazil and is a perennial herb of the family Cactaceae. Its stems are flat and many branches, the appearance of crab claws, bright and shiny flowers, is one of the fine flowers of indoor potted plants. 1. Propagation of C. davidianus uses cuttings or grafting methods, but the growth of cuttings is slow and the shape of the plants is not beautiful. Therefore, grafting methods are often used. Can be grafted all year round, with the best of spring and autumn. Grafting method: Take cactus as rootstock, cut a slit about 3 centimeters deep from the top, use 4 to 5 knots as the cuttings, cut the base of the cutting into a wedge to insert the root into the top of the rootstock, use a pin or Cactus thorns can be fixed, the temperature is maintained at 20 ° C - 25 ° C easy to heal, then 3 days after the watering, about 10 days scion is not wilting is to survive. Second, cultivation and pruning of C. argentinalis can be followed by flowering in the year or the second year, and 1 year - 2 years of young plants to adjust the direction and plasticity. It can be reshaped in two ways: one is supported by various forms of stents, and the other is to make it droop naturally, which can grow to more than 50 cm after 4 years. In order to ensure strong growth and more flowering, crab claws need to be changed once every two years. When changing basins, apply base fertilizer and replace some nutritious soil. The best time is in March. Perennials should be pruned regularly, or too dense branches affect the amount of flowering. Pruning takes place after the flowering in March. The principle of pruning is: strong branch light shearing, weak branch heavy shearing, sparse shearing too dense, retracting long branches. Third, watering and light management Crabgrass like warm and humid climate conditions and humus-rich soil, winter requirements of sunny, summer should be shaded. To keep the basin moist, but not to sink water, irrigate once a week in June-August, and pour it once every 2 days in 3 days in September. Apply fertilizer once every two weeks and control watering after flowering. C. jasminoides is a short-day flower, when flower buds are formed in September, the daily sunshine time should not exceed 10 hours, otherwise it will affect the formation of flower buds. The optimum temperature for growth is 15°C--25°C, but it must not be lower than 8°C. The optimal temperature for flowering is 9°C--12°C and the flowering period can reach two months. Artificially control the flowering period as needed.
