When will the seedlings of water spinach start growing

Water spinach usually starts seedling cultivation from March to April in spring, and the specific time needs to be adjusted according to local temperature, soil moisture, and variety characteristics.

Water spinach prefers warm and humid environments, and can be sown when the temperature stabilizes above 15 degrees Celsius. The climate in the southern region warms up earlier, and seedling cultivation can be carried out in early March, using greenhouses or small arch sheds to cultivate seedlings in advance. The northern region needs to postpone sowing until mid to late April, until the risk of frost is completely eliminated. Before seedling cultivation, it is necessary to select plump and disease-free seeds, soak them in warm water for 6 hours to promote germination, cover them with thin soil and keep the soil moist after sowing, and the seedlings can emerge in about 7 to 10 days. Facility agriculture techniques can be used in high-altitude regions or off-season cultivation to advance seedling cultivation through methods such as plastic film covering and greenhouse insulation. During the high temperature period in summer, it is important to pay attention to shading and cooling the seedlings, and avoid direct exposure to strong light that can cause burns to the seedlings. Cold resistant varieties can be selected for autumn planting, and seedlings should be raised from August to September, but sufficient accumulated temperature should be ensured during the growth period. During the seedling cultivation period of water spinach, it is necessary to keep the soil loose and breathable, regularly check the seedling condition, and if excessive growth is found, control the water and refine the seedlings appropriately. Gradually increase ventilation one week before transplanting to allow the seedlings to adapt to the external environment. Reasonably controlling the seedling cultivation time can effectively extend the harvesting period, achieve batch planting and continuous supply.
