How long does it take to eat water spinach

It usually takes 30 to 45 days for water spinach to be sown and consumed, depending on factors such as variety differences, planting environment, and water and fertilizer management.

1. Variety Differences

There are significant differences in the growth cycle of different varieties of water spinach. Early maturing varieties such as white stem water spinach can usually be harvested for tender stems and leaves in about 30 days. These varieties have delicate stems and smaller leaves, making them suitable for quick harvesting. Late maturing varieties such as large leaved water spinach require more than 40 days to reach their optimal edible state, with thick stems and leaves that require longer time to accumulate nutrients.

2. Planting Environment

The fastest growth occurs when the temperature is maintained between 25 and 30 degrees Celsius, and below 15 degrees Celsius, the growth rate will be significantly delayed. Under sufficient light conditions, photosynthesis is sufficient, which can shorten the maturation period by about 5 days. Hydroponic cultivation can be harvested about 7 days earlier than soil cultivation due to its higher nutrient absorption efficiency.

III. Water and Fertilizer Management

Maintaining soil moisture without waterlogging is most beneficial for growth, as water scarcity can lead to stem fibrosis and delayed harvesting. Weekly application of nitrogen fertilizer can promote leaf growth, but excessive application can reduce food safety. Alternating the use of organic fertilizer and compound fertilizer can shorten the maturity period by 3 to 5 days.

IV. Harvesting Criteria

The optimal harvesting period is when the stem length reaches 15 centimeters and has not yet bloomed. Early yields are low, and late stem lignification occurs. Retaining 2 to 3 nodes at the base can promote secondary growth and achieve multiple harvests. Harvesting should be done in advance during high temperatures in summer to prevent a decline in quality.

Fifth, seasonal influence

Spring sowing takes about 50 days, and summer sowing takes 35 days to harvest. The large temperature difference between day and night in autumn may extend to 55 days. Greenhouse cultivation can produce year-round, shortening the cycle by 10 days compared to open field cultivation. Continuous rainy weather can delay growth by 7 to 10 days. When planting water spinach, it is recommended to choose fertile soil with good drainage and maintain at least 6 hours of sunlight per day. Stop fertilizing 3 days before harvesting to ensure food safety, and gently pinch the stem with your fingertips to break it smoothly, which is the sign of maturity. Attention should be paid to supplementing trace elements during multiple harvests to avoid soil nutrient imbalance. Hydroponic cultivation requires regular replacement of nutrient solutions and control of EC values within the range of 1.2 to 1.6 ms/cm. For home planting, the pinching harvesting method can be used to extend the harvest period, and diluted fish protein fertilizer can be applied after each harvest to promote the germination of new shoots.
