1、 Fallen leaves

Rhododendron leaves in winter, which is a normal phenomenon, but generally the old leaves will fall, and there will be no large-scale defoliation. If a large area of leaves of the plant are found to fall, it is likely to be caused by improper maintenance. However, there are many varieties of Rhododendron, and some varieties will not shed leaves

2、 Winter curing

When cultivating Rhododendron in winter, we should pay attention to cold protection, especially in the northern area. Don't spend the winter in the open air. After the beginning of winter, it should be kept indoors, and the temperature should be controlled at 8-10 ℃. It should also be exposed to more sun. In winter, the sun is not strong, so it can see light all day. At this time, it needs less water, so it should be watered sparingly. If the soil is not dry, don't water it. Don't fertilize it. Just apply base fertilizer once in January next year, which can promote its spring flowering

3、 How does the leaf turn white

When the Rhododendron leaves turn white, it is likely to be infected with the disease. When the plant is infected with powdery mildew, the leaves will turn white. You should buy medicine immediately, or spray it with green onion liquid or rice vinegar, which can also play a therapeutic role. In addition, the maintenance environment is airtight and the temperature is too high, so the maintenance methods should be changed. In addition, if it is caused by Starscream, insecticide should be used to kill it
