Four reasons for the failure of Phalaenopsis family cultivation
1, watering frequency: cultivation of Phalaenopsis friends, always worried about water shortage, regardless of whether the cultivation medium is dry, watering every day, causing serious rotten roots.
2, the temperature is too low: usually Phalaenopsis flowering plants listed in the early spring, and buy home are generally placed in the living room and other places to enjoy, although the day temperature in these places is enough, but the night temperature is a little too low. Professional orchids, on the other hand, are mostly grown in well-equipped greenhouses, compared with homes where the temperature and humidity are slightly inadequate, making the plants tend to grow weaker and weaker. Therefore, orchids sometimes fail to bloom, no matter how well they are maintained.
3, excessive fertilization: there is fertilizer on the application, and do not pay attention to the concentration, feel that the fertilizer will grow fast. Phalaenopsis should be thin fertilizer, should be a small number of times. Remember that "tonic" can not be excessive, otherwise counterproductive.
4, small plant planting large pot: I think with a large pot, you can give Phalaenopsis a loose environment, the materials are sufficient. After its practical big basin, aquatic is not easy to dry, notice phalaenopsis likes aerate, gas general rule is comfortable.

The occurrence of the disease can be controlled by uniform spraying with 800 times of Prike solution, once every 5 days, for 3 consecutive times. The symptoms of soft rot are leaf base rot, corm rot and mildew bacterial smell. Methods of prevention and treatment: agricultural streptomycin sulfate was sprayed at the initial stage of the disease, once every 7 days, for a total of 2 times.
