Families raise azaleas well.

Rhododendron is a perennial woody plant, like cool and humid climate, like semi-shady sun exposure, like fat avoid thick fertilizer, suitable for growing in permeable slightly acidic sealed soil. So azaleas grow most vigorously at about 20 ℃; stop growing at more than 30 ℃ and stay dormant; if they are on the job, they will not freeze to death. But I am afraid of a sudden attack by the cold wind. Therefore, azaleas should be kept away from the heating and stove indoors, receive plenty of sunshine in winter, shade in summer, and be placed on a well-ventilated north balcony (or outside the north window). Watering is the same as other flowers, wet and dry, often lack of water will affect growth, watering too much will rot roots, resulting in death. Water twice a day in summer, once a day at other times, and only once a few days in winter. Water for watering flowers should be reused after a few days, and 0.2% ferrous sulfate should be watered every 10-15 days, or a few drops of edible vinegar can be dropped in the water. Fertilization is carried out in accordance with the principle of "thin fertilizer and frequent application", the finished flower fertilizer is prepared and used according to the regulations, and the self-retting fertilizer should be lightly added to the water and used during watering, and there is no fertilization during flowering. Spray to the foliar fountain 2-3 times a day to increase humidity. The flower soil should use the special soil prepared by larch. Azaleas can blossom all the year round, and the flowering period is longer. As long as the cultivation conditions are right, it can last more than three months from the first flower to the full bloom. According to the need, it is generally mainly allowed to blossom before the Spring Festival, at this time, nature has lost its green, flowers are also gone, and during the festive festival, buy a few pots of azaleas, whether you enjoy them or give them to relatives and friends, it is the best choice.
