1, if the water spinach is planted in the greenhouse, it is usually planted around10-1February every year, and it can be harvested and marketed after 2-3 months.

2. Because water spinach is a kind of vegetable with fast growth speed and strong branching ability, it needs enough water and fertilizer, so as not to affect its growth.

3. It is the key to prevent freezing and heat preservation in greenhouse planting in winter, because the temperature is too low and the air humidity is too high, which is very unfavorable for the growth of spinach, so we should choose the weather with good light and little temperature difference. In cold weather, the temperature in the shed should be kept above 10 degrees Celsius, otherwise it will freeze; In hot weather, the temperature in the shed should not exceed 35 degrees Celsius, and ventilation and dehumidification should be maintained; If the air humidity is too high in rainy days, the plastic film around the greenhouse should also be uncovered.

4. Generally, after harvesting the water spinach once (it should be harvested in time when it is about 35cm long), new leaves will be produced after a while, and it can be harvested again. Therefore, while ensuring soil base fertilizer, top dressing must be done on time. After harvesting and topdressing, water the soil in time to keep it moist.

5. Water spinach planted in greenhouse is prone to stem rot and damping-off under the condition of low temperature and high humidity. The main pests and diseases are red spiders and mites, so it is necessary to do preventive work in advance.
