1、 Curing method

1. Temperature: 15 to 28 degrees is the most suitable range. In the environment above 35 degrees, its growth rate will be very slow or even stagnant. Under the condition of less than ten degrees, it is possible to be frozen. Therefore, under these two extreme conditions, attention should be paid to regulation

2. Light: watercress has high requirements for sunshine. When it is too dark, its flowering will be very adversely affected. Generally speaking, there is no shade in winter and spring. In summer and autumn with strong sunshine, shade is needed

3. Watering: watercress likes to be wet, but its waterlogging resistance is not very good. In summer, try to moisten the basin every two days and pour it thoroughly twice a month. The spring and autumn seasons are basically the same. Generally, the basin is moistened twice a week and watered thoroughly once a month. Water control is required in winter. Generally, the basin is moistened once a week

4. Fertilization: it doesn't need much fertilizer. Select nutritious soil, and add sufficient fertilizer when planting and changing pots, so there is basically no need for topdressing. Too much fat can cause harm

2、 Breeding skills

1. Reproduction: it can be propagated by ramets. Before breeding, it is necessary to control the water for a period of time. Then there are the specific steps of plant division. When separating, pay attention to that each part must have several pseudobulbs. Then prepare sandy soil as matrix. After planting separately, pour it thoroughly, and then place it in a cool place

2. Changing pots: watercress has high requirements for soil quality, so it's best to change the soil regularly, preferably once a year. In this way, it can not only ensure sufficient nutrients in the soil, but also avoid serious soil caking. However, when changing pots, you should pay attention to slightly pruning the roots and leaves, but don't hurt the taproot

3、 Problem diagnosis and treatment

1. Diseases: some diseases occur more frequently in summer and autumn, such as "anthrax", "leaf spot" and so on. In addition to cutting off the infected leaves and treating them well, it is best to use some drugs to recover quickly

2. Insect pests: mainly "aphids" and "red spiders". Generally, the effect of various chemicals is good, which is easy to control

4、 Other issues

1. Toxicity: watercress is a kind of orchid. It is non-toxic and has strong purification ability

2. Whether it can be raised at home: it is good to put it at home as a potted plant
