How to cultivate potted azaleas?

How to cultivate potted azaleas? What do potted azaleas need to pay attention to? Also ask experienced netizens to help introduce azaleas, also known as Yingshanhong and pomegranate, as evergreen or ordinary green shrubs. According to legend, in ancient times, there were cuckoos, whining day and night and hemoptysis, dyed red flowers all over the mountain, hence the name. The planting network has sorted out the cultivation methods and matters needing attention of potted azaleas, which are listed in detail below for netizens' reference. Rhododendron cultivation soil and plant pot selection: rhododendron is a shallow root acidophilic flower (pH4.5-6.5is suitable), the root is as fine as silk hair, distributed in the upper layer of the basin soil, so the most avoid heavy clay and alkaline soil. Acid culture soil must be used for reproduction or planting. You can use half of peat soil and half of plain sand, add a small amount of rotten leaf soil and barnyard manure for a period of time, and the effect of fertilizer soil is very good. Rhododendron pots should not be too large and too deep, and tile flowerpots with good permeability should be selected according to plant size. Do not break up the pots or change the soil. Management of azaleas: spring, summer and autumn should be maintained in sparse shade. Water should be sprayed frequently before the rainy season to improve air humidity, but water should not be sprinkled on the building to prevent rotten leaves. The basin soil should be wet between the dry and dry, not stagnant water. If it is found that the leaves turn yellow, ferrous sulfate 500 times solution should be irrigated immediately. Do not force the application of heavy fertilizer, let alone chemical fertilizer, it is best to often irrigate the grass instead of fertilizer, which is very beneficial to flowering. Move indoors before winter, keep room temperature about 15 ℃. It blossoms in early spring. Pruning the azaleas: the leaves of the azaleas are whorled at the top of the short branches and blossom in the leaves; after the flowers fade, new branches and new leaves are produced from the terminal buds, the old leaves fall off, and then the flower buds are differentiated from the terminal buds of new technologies, and bloom again next year. Therefore, the branches should not tremble for a short time, but should be allowed to grow naturally. The branches on the plant are evenly distributed and hierarchical, and the plant shape will not be disorganized without pruning. Potted azaleas need to pay attention to: first, azaleas like yin and fear the sun, strong light is easy to burn, but excessive shading will cause poor growth and flower buds are not easy to form. Second, the rhododendron is physiologically deficient in iron, which affects the synthesis of chlorophyll, resulting in smaller leaves and yellowish white. Third, generally can withstand the low temperature of less than 10 ℃, but because the rhododendron root is shallow and thin, close to the topsoil, can not withstand the heat. Fourth, because the rhododendron has a slender root system and poor water absorption and supply capacity, it is afraid of drought and waterlogging, and it can only grow well when the air humidity is 70% to 90%. Fifth, the azaleas should be properly watered. If the surface is wet and dry, the roots will be damaged and the old leaves will fall early; if the roots are rotten with stagnant water, the new leaves will be white and yellow; the flowers will be short of water and the petals will droop; when the leaves are short of water during the leaf expansion period, the heart leaves will curl and the leaves will turn yellow. Sixth, azaleas, such as lack of nitrogen fertilizer, thin leaves, short and thin branches, few and small flowers; rhododendrons lack phosphate fertilizer, some leaves are reddish purple and easy to fall; when azaleas lack potassium fertilizer, old leaves are gray-green, leaf edges are yellow-green, leaves appear spots, and finally turn brown, even scorched fallen leaves. Seventh, if the fertilizer is too thick and sufficient, it will cause reverse osmosis to the azaleas, the whisker root will shrink due to water loss, the leaf tip and leaf edge will lose luster, and gradually zoom and fall off. Eighth, poor ventilation, air blockage, will also cause rhododendron leaves. 9. Cuckoos are afraid of snow and frost, and it is appropriate to overwinter at about 8 ℃. If the room temperature is too high to dormancy, the physiological activities do not decrease, and continue to consume a large amount of nutrients, it will be disadvantageous to the growth and development of the following year.
