What are the methods and precautions for raising hibiscus flowers
As an ornamental flower native to the tropics, hibiscus flowers are deeply loved by gardening enthusiasts for their unique flower appearance that opens in the morning and closes in the evening. If hibiscus flowers want to continue to bloom pink-purple flowers, it is particularly important to master scientific maintenance methods. This article will systematically explain the key points of hibiscus flower cultivation from environmental regulation to pest and disease control. Light control and temperature management are the four core elements of hibiscus flower cultivation. Hibiscus flowers require 6-8 hours of sufficient light every day, and can be maintained under full sunshine in spring and autumn. In summer, sunshade nets need to be erected between 11 and 15 o'clock to avoid leaf burns and forming brown spots. Keep the wintering temperature above 10℃ in winter, and it is recommended to move it into indoor window sills for maintenance in northern areas. Soil configuration and nutrient supplement use a mixed substrate of legus soil + garden soil + coarse sand (5:3:2), and bone meal is added as base fertilizer when changing pots every two years in spring. Phosphorus and potassium liquid fertilizer diluted 1000 times is applied every half of the month during the growth period, and potassium dihydrogen phosphate is added during the bud appearing period to promote flower bud differentiation. Scientific watering techniques adopt the principle of "seeing the dry, seeing the wet". Pour water thoroughly in 3-5 days in spring and autumn, and spray in the morning and evening to increase moisture in summer. Determine the moisture status by observing the state of the leaves: water needs to be replenished when the leaves droop, and water is reduced when the leaf tips are black. In the rainy season, drainage needs to be carried out in time to avoid accumulation of water in the basin soil for more than 24 hours. Three major precautions for hibiscus flower management pest control plan Red spiders are common in dry environments, and you can use 40% dimethoate EC to spray the back of the leaves at 1500 times liquid. When larvae bite young leaves, it is recommended to hang yellow sticky boards for physical control, and alternately use cypermethrin and emamectin salt in severe cases. Brown dots appear in the early stage of leaf blight in the disease warning system. The diseased leaves need to be removed immediately and sprayed with 50% carbendazim 800 times solution. Spray Bordeaux mixture at 1:1:200 before the rainy season to prevent brown spot disease, and maintain plant spacing to enhance ventilation and light transmission. Pruning and shaping strategy Carry out retraction pruning after flowering, and retain 30-40cm of the main stem to promote the germination of new branches. Cut cross branches and overdense branches to improve plant type. After pruning in winter, apply healing agents to wounds to prevent the invasion of bacteria.
By accurately controlling the four major elements of light, warm water and fertilizer, and combining with comprehensive pest control, hibiscus flowers can continue to bloom all year round. Regularly observing the status of the plants and adjusting maintenance strategies in a timely manner will surely make this beautiful flower that is "picked up in the morning and at night" a highlight in the courtyard.
