杜鹃花,花形千姿百态,招人喜爱。但杜鹃好看难养,往往花后即亡,或不知不觉死亡。怎样防止杜鹃死亡呢?可采取如下措施:一、要使土壤呈微酸性或中性,保证杜鹃生长旺盛。杜鹃花如果浇上盐水或咸鱼水、菜汤等污水,会造成死亡。发现这种情况后,立即洗根,换土,套上塑料袋挽救,可望成活50%左右。在土壤连续15～20天含水量超过85%～90%,杜鹃要烂根、枝枯、叶落、死亡。一般盆土要保持湿度50%左右或60%。土壤作用大时,更为严重。因此不能让盆土长期干燥。一般干1～2天问题不大,正常管理要经常保持盆土湿润。
Azaleas, flower-shaped mix, recruit. However, Rhododendron looks so hard to raise, often after blooming, or unknowingly dead. How to prevent the death of azalea can take the following measures: First, to make the soil slightly acidic or neutral, to ensure vigorous growth of azaleas.

Found this situation, immediately wash the roots, soil, put on plastic bags to save, is expected to survive about 50%. 15 to 20 days in the soil water content of more than 85% to 90%, rhododendron to rot, root blight, leaf fall, death. General peat soil humidity to maintain about 50% or 60%. When the soil is large, it is more serious. Therefore can not make long-term basin pots dry. Generally dry 1 to 2 days is not a problem, normal management should always keep basin moist.
