1、 Soil
Rhododendron is suitable to grow in acidic soil with good drainage. A small amount of peat soil needs to be added to the alkaline soil in the north. For potting, you can prepare basin soil by yourself, mainly rotten leaf soil, and add a small amount of sand to strengthen the drainage capacity. In addition, certain cake fertilizer can be added to provide nutrients for its growth p>
2、 Illumination
Rhododendron prefers a semi shady environment with good ventilation. The light should not be too strong. It can be placed in a place with scattered light for a long time. In summer, we should pay attention to shade and avoid strong light exposure, otherwise the leaves will be sunburned and the plant will die p>
3、 Temperature
Rhododendron can grow normally in the environment of 12-25 ℃. If the temperature is higher than 35 ℃ in summer, its growth rate will slow down and enter a semi dormant state. Proper cold prevention measures shall be taken in winter to avoid plant frostbite. The temperature shall not be lower than 5 ℃. When the temperature in the north is too low, put it in a warm place indoors, or wrap the plant in a bag to keep warm p>
4、 Watering
Rhododendron has a high demand for water. It can't wait until the soil is dry before watering. It is necessary to keep the substrate moist at any time. Generally, water once every 2-3 days and every day in summer. Don't use tap water directly. It's best to let it stand for a few days before watering. In addition, the water temperature should also be well controlled. Too cold water will affect the water absorption function of the root p>
5、 Fertilization
Fertilization of Rhododendron is generally in spring and autumn. Summer and winter enter the dormancy period, and fertilization is easy to accumulate, resulting in too thick fertilizer. During the growth period, apply cake fertilizer and water every 10 days. Topdressing once every 15 days after flowering to supplement the nutrients consumed by flowering. Apply more phosphorus and potassium fertilizer before winter to help the plant survive the winter p>
