Water requirement of Rhododendron
1、 Watering frequency
Rhododendron is relatively fond of water in the growing period, so it is necessary to keep sufficient water in the period of more water demand. Under normal circumstances, that is, in the spring and autumn growth period, 2-3 times of water supply can be guaranteed every week. In summer, water evaporation is very strong, watering should be timely, you can water every day. In winter, the temperature gradually decreases, the growth rate slows down, and the watering should also be reduced. Water should be given every ten days and a half months to keep it dry.
2、 Water spray for moisturizing
In addition to normal watering to maintain growth, spray water mist around the plant in summer to reduce temperature and increase humidity.
3、 Watering time
Watering time should be well controlled, which is also very important. If the watering time is not well controlled, it may affect the normal growth of plants. In summer, water supply should be avoided in the morning and at night. In winter, the temperature is too low. Watering sooner or later will cause frostbite to the plant, so it can be watered at noon.
4、 Water quality selection
Rhododendron is a kind of acid loving flower. It is difficult to grow normally in alkaline environment, which may lead to growth problems. The best choice of water quality is acid water, rain water can be selected, or evaporated tap water can be used. In order to increase the acidity, vinegar can be added appropriately.
