How to plant RhododendronToday, the editor will explain how to plant Rhododendron and introduce the planting techniques of Rhododendron in the aspect of green plants and flowers. Here is the detailed introduction.Rhododendron comes in many varieties with beautiful and colorful flowers, making it highly ornamental. According to flower color, blooming period, and shape, Rhododendron can be divided into many types. Its leaves are ovate or elliptical, 1.5-5 centimeters long and 0.5-3 centimeters wide, with fine teeth on the edges. The upper surface is dark green with sparse rough pubescence, while the lower surface is light white and densely covered with brown rough pubescence.The flowers cluster at the top of the branches, with a broad funnellike corolla that is pink or dark red, 3 centimeters long and 2 centimeters wide. The blooming period is from April to May, and the fruiting period is from June to August.Rhododendron growth environmentRhododendron prefers shade and is not cold or drought resistant. The optimal growth temperature is between 12°C and 25°C, suitable for a cool, humid, and well-ventilated environment. High temperatures will cause the new leaves to grow slowly. In addition, Rhododendron prefers acidic soil.Rhododendron cultivation methodsRhododendron is commonly propagated by播种(sowing), cutting, and grafting, and can also be propagated by layering and dividing plants.Cultivation precautions1. Light and temperature: Based on the growth environment of Rhododendron, we need to pay attention to maintaining the soil's ventilation during cultivation and choose well-draining acidic soil. Provide moderate sunlight and avoid direct strong sunlight.Excessive light can burn the tender leaves, cause the edges of new and old leaves to become crispy, and in severe cases, lead to plant death. The optimal growth temperature is between 15°C and 25°C. Therefore, in winter, it should be moved indoors and placed in a sunny location for warmth. In summer, it should be shaded.2. Fertilization and water management: Rhododendron prefers moist soil, so it should be kept slightly moist, with watering once a week in winter. Do not water when the soil is not dry, and if watering is necessary, make sure to water thoroughly, preferably with acidic water. Rhododendron requires more water during the growing season, and the amount of water can be reduced before and after flowering. Additionally, Rhododendron prefers light fertilizer. Adjust the amount of fertilizer based on different growth stages. Fertilize once a week during the growing season, and avoid fertilizing in summer. From September, apply a 20%-30% phosphorus-containing liquid fertilizer every 10 days to promote the growth of Rhododendron flower buds. After October, growth essentially stops, and fertilizing should cease. It is best to use acidic and low-alkaline fertilizers, choosing fertilizers with moderate nutrient release, long-lasting effects, and high nitrogen, phosphorus, and potassium content.3. Pest control: Strengthen cultivation management and pay attention to the growth of Rhododendron. If pests are found, they should be dealt with promptly. Common diseases and pests of Rhododendron include root rot, red spider mites, and gray mold.Rhododendron root rot: Promptly dispose of dead plants and potting soil. Increase sunlight in the morning and evening, apply potassium fertilizer, and enhance the disease resistance of Rhododendron.Rhododendron red spider mites: Use a 10%天皇星 emulsion diluted 1000 times or a 7051 insecticide (灭虫灵) diluted 3000 times to spray and kill.Rhododendron gray mold: Use a 50% chlorothalonil solution diluted 1000 times or a 50% carbendazim wettable powder solution diluted 1000 times to spray and control.This article shares all the content about how to plant Rhododendron and its cultivation techniques.
