How to raise hibiscus
As a traditional flower with both ornamental and medicinal values, hibiscus is deeply loved by gardening enthusiasts for its unique flower appearance that opens in the morning and falls in the evening. But for this summer elf to continue to bloom, we need to master a scientific maintenance system. This paper will systematically analyze the five core elements of hibiscus conservation, from environmental regulation to pest control. The soil matrix ratio of basic conditions for hibiscus maintenance adopts the gold ratio of legus: perlite: vermiculite =5:3:2, and the bottom layer is paved with 3 cm ceramite to enhance water permeability. Supplement organic fertilizers such as bone meal or earthworm cast every quarter to maintain soil pH at 6.0-6.5 in a slightly acidic environment. Before the rainy season, loosen the soil to a depth of 20cm to prevent water accumulation. Light intensity is controlled to receive scattered light for 5 hours in spring and autumn, and 30% sunshade net is used for protection in summer. Special attention should be paid to avoid direct radiation from 11 to 14 noon. You can adjust it by observing the condition of the leaves: curling of the leaves means that the light is too strong, and light needs to be replenished if the leaves are dim. During the collaborative management of water and fertilizer, the "morning watering and late inspection" system is implemented, and the Merlek flower-type nutrient solution (diluted 1000 times) is applied every 10 days. During the winter hibernation period, water is supplied by dipping basin method, and the substrate humidity is maintained at about 40%. Key fertilization nodes include increasing application of phosphorus and potassium fertilizers during the budding period and supplementing balanced fertilizer after flowering. Advanced Hibiscus Cultivation Skills Cutting Breeding Practical Practice How to raise Hibiscus
Select semi-lignified branches, retain 3-4 bud points, cut 45° and obliquely, and soak in rooting powder solution for 2 hours. Using a cuttage substrate made of perlite + peat, maintaining an environment with a humidity of 80% and a temperature of 25℃, and using a regular spraying system, a rooting rate of 90% can be achieved within 15 days. Three-dimensional prevention and control of pests and diseases has established a three-layer protection system focusing on prevention: yellow sticky insect boards are used for physical protection, natural enemies such as ladybugs are introduced for biological control, and imidacloprid (2000 times liquid) is sprayed for half a month for chemical control. Pay special attention to the alternating use of mancozeb and carbendazim before and after the rainy season to prevent (T-J) disease.
Through scientific regulation of light, precise water and fertilizer management, and establishing an early warning mechanism for pests and diseases, hibiscus can achieve ornamental effects of blooming for more than 200 days a year. Regular pruning to maintain ventilation and light transmission, and in conjunction with the maintenance priorities of different seasons, this classical beauty of "picking up flowers in the morning and at night" can be permanently resident in the courtyard.
