5 water plants.

One is to choose slightly acidic water. Azaleas prefer slightly acidic water and avoid alkaline water. If alkaline water is often used to irrigate the cuckoo, it will not take long for the cuckoo to die. For the choice of water quality, it is generally appropriate to use natural water with a pH value below 7 or drinking tap water. If the water quality does not meet the acidity requirements, 0.1% ferrous sulfate or 0.5% vinegar can be added to the water.

The second is to use "trapped water". Usually, you can be trapped in the water for two or three days. The "trapped water" should be dried at the same temperature of the azaleas, which has the following advantages: first, it can reduce the chlorine element in the water that is harmful to the growth of rhododendrons; second, it can increase the water temperature and eliminate the temperature difference between water and basin soil; third, promote microbial activity and organic matter decomposition, which is conducive to root absorption.

Third, it should be dry or watered. A flower proverb says that it all depends on a pot to grow flowers. It means that it is necessary to master the amount of water for watering flowers. One of the keys to watering azaleas is not to dry or water them. What is dry? This can not only see whether the surface of the basin soil is dry or not, it is more important to knock on the basin and listen to the sound, which is wet when the sound is dull and dry when the sound is crisp. Don't dry too much, the leaves will wilt.

Fourth, it must be watered thoroughly. How can it be thoroughly watered? Planting cuckoos generally leave a nozzle of about 1 inch, and in most cases it can be permeated as long as it is fully watered. But if the soil is flat with the basin mouth or the nozzle is too shallow, it will be difficult to pour it through at one time.

Some large basin soil dry, there is a gap around, easy to run water, looking at the basin leakage, but only wet the upper layer and around, the basin soil is not thoroughly watered, should be watered again at this time. To cultivate azaleas, only by grasping the key point of "no dry, no watering, watering must be thoroughly", can we promote fertilizer with water, regulate air with water, and promote plants with deep roots and luxuriant leaves.

Fifth, the four seasons should be different. In spring and autumn, rhododendron is in its growing period, so it is necessary to ensure sufficient water, especially in spring, when watering times should be relatively increased. At the same time, foliar and ground should be sprayed frequently to maintain environmental humidity and reduce foliar water transpiration. The temperature is high in summer and the water evaporates quickly, so it can be watered once in the morning and in the evening.

In winter, the physiological activity of rhododendron is greatly weakened, and it does not need too much water, as long as the pot soil is kept dry, which is beneficial to overwintering. If the winter watering frequently, basin soil is too wet, easy to rot roots, easy to die in spring, even if not dead, it is difficult to grow exuberant. In addition, the flowering period should not be too much watering, too much water is easy to drop buds or early thanks, at this time, as long as there is no shortage of water.
