How to raise azaleas on the balcony
The growth of rhododendron needs moist, ventilated, cool environment and acid soil with good ventilation and permeability. Among them, temperature, humidity, wind, and light are particularly important for the azaleas in the balcony, because the balcony is hot and stuffy, Drying is the least suitable for growing azaleas. How to eliminate these unfavorable factors is the key to maintaining good azaleas. 1, wet in the balcony to create a relatively high relative humidity environment, referring to the air humidity, must not be mistaken for the basin soil moisture. The specific method is to use slightly larger than the mouth of the flower pot utensils to do the tray, disc depth of about 10 cm, the bottom is not leaking, the first padding 3-5 cm river sand, flat, poured water, the amount of water does not exceed the sand plane It is advisable to place the azalea pots on the sand surface. We often keep the river sand moist, so as to increase the air humidity in the pelvic wall and roots, and depending on the weather condition, spraying water on the leaf surface, we can better adjust the air humidity, so as to achieve the purpose of root protection, escorting roots, and rooting. In order to achieve prosperity. The requirement for air humidity of the blades is more sensitive than the roots. Creating a good air humidity for the blades is the key to raising the rhododendrons on the balcony. Because the moisture in the wetted sand in the flowerpots and trays is limited, especially in the dry season. This moisture is easily evaporated, making it difficult for the leaves to receive moist air. In order not to let moisture run away, a plastic film cover can be used to cover the flowerpots and trays. The ventilation is often used to lift the hood. The relative humidity at night can be large, and the high temperature at night can not cover the hood. Large leaf spray to increase humidity. In winter, when the temperature of the balcony is too low, the trays can be moved into the indoor hood together with the flowers, and then placed in the position of the sun, and the ventilation is removed once a few days so that the air humidity in the hood is suitable for the growth of the azaleas. 2, mild light summer balcony temperature is above 30 degrees, particularly strong light, the growth of azaleas adversely, as the saying goes "long do not look at May, die to see July." If not properly managed during this period, Du Fu is most likely to die Therefore, it is particularly important to take correct and effective cooling and shading measures, and it is reasonable to shave light from 50 to 60%. Shading is mainly in late spring, summer and early autumn. At the same time strengthen the leaf spray management, in order to achieve the purpose of cooling, moisturizing, cold in winter, long-term below zero, azalea will freeze to death, so the winter must take insulation measures, the temperature of 15 degrees or more is the best. 3, the wind in addition to winter, the balcony long hot, this environment is induced by black spot, lobular disease is the main reason, these diseases are the enemy of the growth of azalea often open the balcony window to ease the hot, to achieve ventilation, cool effect . As long as the proper regulation of temperature, humidity, wind, and light can be achieved, it will not be difficult for the balcony to maintain a good azalea.
