How to grow water spinach for high yield

1. Plot selection

When planting water spinach, you should choose loam plots with fertile soil, deep soil layer and good air permeability. It does not grow well in clay and sandy soil. In addition, water spinach needs an environment with sufficient light to grow. It is easy to grow poorly if the light is not good. Therefore, water spinach is rarely planted in the corners in front of and behind houses.

2. Planting time

Water spinach likes a warm and humid environment. It is usually sown when the minimum temperature is stable at above 15 degrees from late April to early May. The seed coat of water spinach seeds is very thick. In order to promote germination, they can be soaked in clean water to germinate. Water spinach is usually planted in holes, with a row spacing of 40cm and a plant spacing of 30cm. 4-5 seeds are sown in each hole.

3. Suitable for watering

Water spinach likes a humid environment. In some areas in the south, it is planted directly in water. The soil should be kept moist during the growth period. It should be watered every three or four days in summer, and every five or six days in spring and autumn. The amount of water used each time should not be too large. Drip irrigation, micro-spraying and other equipment can be used for irrigation.

4. Appropriate fertilization

Water spinach is harvested many times, and its need for nutrients is relatively large. It is necessary to choose a plot with fertile soil for planting and apply sufficient base fertilizer. In addition, appropriate amount of topdressing is required during the growth process. Topdressing should be done three or four days after the wound of water spinach has healed. Topdressing should be mainly nitrogen fertilizer, combined with phosphorus and potassium fertilizers.
