What are the characteristics of azaleas? Please give an introduction to Rhododendron species, habits vary greatly, but most species produced in high-altitude areas, like cool, humid climate, heat and dryness. Humus rich, loose, moist and acidic soil with pH between 5.5 and 6.5 is required. Some species and horticultural varieties have strong adaptability, drought tolerance, barren, soil pH value between 7~8 can also grow. However, growth is poor in heavy or poorly permeable soils. Azaleas have certain requirements for light, but they are not resistant to insolation. In summer and autumn, deciduous trees or shade sheds should be used to block the sun, and water is often sprayed on the ground. Azalea shoot generally in spring and autumn two seasons, mainly spring shoots. The most suitable growth temperature is 15~20 degrees Celsius, and the temperature exceeds 30 degrees Celsius or below 5 degrees Celsius, the growth stagnates. Winter has a short dormancy period, after the temperature rises, flower buds gradually expand, generally open field cultivation in March to May flowering, high altitude areas late to July to August flowering. North is cultivated in greenhouses. They can bloom in January or February. Rhododendron pruning tolerance, hidden buds easily stimulated germination, can be used to control tree shape, rejuvenation tree body. Generally pruned before May, the new shoots can form flower buds in the same year, too late to affect flowering. Generally, new shoots germinated around the beginning of autumn can still be lignified. If new shoots are formed too late, they are vulnerable to freezing injury in winter.
