Potted azaleas are usually raised like this. It's not too late to know.

There are many kinds of azaleas, leaves and beautiful flowers. Suitable for planting and potted plants. It is one of the top ten traditional flowers in China. Legend has it that Rhododendron is made from a bird spitting blood, also known as Yingshanhong. Rhododendron is a neutral flower with a warm, semi-shady, cool, ventilated and humid environment. Plenty of sunshine, avoid basking in the sun, afraid of cold, avoid dense fertilizer, not resistant to stagnant water. Many people die before they blossom. The causes of death are usually as follows:

Not ventilated

The indoor environment is in a relatively closed state, and the air circulation is bad, which is combined with human activities, which leads to the increase of indoor harmful gases. The azaleas are cool and refreshing. If poor ventilation, easy to form high temperature, hot, dry environment, prone to brown spot, red spider and other diseases. Therefore, potted cuckoos should often open windows for ventilation, improve ventilation conditions, and often spray branches and leaves with water to increase humidity and reduce watering.

Insufficient light

Rhododendron is a cool, humid, ventilated semi-cloudy environment. It is afraid of extreme heat and cold. In summer, it should be sunscreen and shade. You should keep warm and cold in winter. Avoid sunlight, suitable for growth under scattered light intensity. The flowering period of rhododendron is longer, a large amount of nutrients in plants are consumed, indoor cultivation compared with natural growth, serious lack of light, photosynthesis is affected, nutrients can not be replenished in time, the plant will become possible. Die of death. In spring, early summer and winter, daylighting should be done in the morning to avoid prolonged exposure to weak light.

Insufficient acidity of soil

Rhododendron has loose soil, strong permeability, good drainage and rich in humic acid. Rhododendron is also a fibrous root plant. It is suitable for soil pH 5.5 ~ 6.5. If it grows in clay or alkaline soil, it can cause small azaleas, dried stems and branches, or even death. When rhododendron is irrigated, a small amount of vinegar or ferrous sulfate is added to effectively increase the pH value of the soil and make the soil more suitable for the growth of rhododendron.

Water and fertilizer are unreasonable

Cuckoos have thin roots, so they are afraid of drying and fetching water. Too much watering will lead to fallen leaves and buds. If they are often in a state of excessive moisture, they can easily lead to the death of rotting roots. The water should be watered moderately. The soil should be dry and moist. Keep the air humidity above 70%. Strictly control moisture and maintain soil microtide in winter. Azaleas are very fat and do not contain rich fertilizers. During the Spring and Autumn period, peppermint fertilizer and liquid water grew for 1 day and 10 days. It can be fermented with boiling water, peel and vegetable leaves. In autumn, you can also add some phosphorus and potassium fertilizer, which can be made from fish, chicken organs, minced meat, rice peel and pericarp. We must apply thin fertilizer and pay attention to fertile fertilizer.

Lack of room for growth

The size of the azaleas is uncomfortable or has not changed in the basin for a long time. There will be a small plant, too long, too dense and insufficient growth space, which leads to nutrient depletion and depleted death. Therefore, azaleas do not need to carry soil every year. Usually 2 to 3 years, minimize the damage to the root, the time should be flower fade or autumn. At the same time, it is necessary to eradicate excessively long fibrous roots and roots, dry roots, replace new soil, and promote root metabolism.
