"Azaleas" are not easy to raise
As one of the top ten famous traditional flowers in China, rhododendrons are deeply loved by flower lovers for their colorful colors, but many people often encounter falling leaves and not blooming during the maintenance process. In fact, as long as you master key maintenance skills, you can make this "beauty in flowers" undefeated. Core maintenance four elements acidic soil ratio Rhododendron root system is extremely sensitive to the soil environment, and an acidic substrate with a pH value of 5.5-6.5 needs to be prepared. Recommended formula: 5 parts of leaf soil +3 parts of pine needles +2 parts of perlite, supplemented with ferrous sulfate solution every six months. Pay attention to avoid using calcareous materials and regularly check the soil pH. Precise moisture management adopts the dual water supply method of "dipping basin + spraying": dipping basin twice a week in spring and autumn (the water level reaches 1/3 of the basin height), and spraying the leaves every morning and evening in summer. Control the watering frequency in winter and keep the substrate moist. Special reminder: Use soft water that has been dried for more than 3 days and avoid using tap water directly. Scientific lighting controls full sunshine in spring, builds a 50% sunshade net in summer, and moves it to the southward sill in autumn and winter. During the flower bud differentiation period (September to October), direct light needs to be guaranteed for 6 hours a day. Appropriate scattering of light during the flowering period can prolong the flowering period. Pay attention to rotating the flowerpot regularly to ensure uniform light reception.

Shape trimming: Shape immediately after flowering, retain 3-5 main branches, and remove crossing branches. Pest and pest control: Alternate monthly spraying of carbendazim and imidacloprid, focusing on preventing red spider and leaf spot diseases. Temperature management: It is best to keep it at 15-25℃, no lower than 5℃ in winter, and cool down through water curtain in summer.
Through systematic maintenance and management, rhododendrons can achieve evergreen seasons and annual flowering. It is recommended to establish a maintenance log to record each watering and fertilization data, and dynamically adjust the plan based on the plant growth status. When new leaves appear yellowed in the plant, iron chelate fertilizer should be supplemented in time; potassium dihydrogen phosphate should be added during the bud formation period.
