When planting water spinach, it is necessary to raise seedlings on land first, and the time of raising seedlings should be around March of the lunar calendar every year. The soil should be sandy soil and there should be water sources that are easy to irrigate. After the seeds of water spinach are sown, they are cultivated to emerge, and can be transplanted to the water surface after 20 days.

To choose an unpolluted water surface, the most ideal place is Misgurnus anguillicaudatus pond, because most of such ponds will not be polluted, and the feces of Misgurnus anguillicaudatus can also be used as fertilizer for spinach, which is beneficial to the growth of spinach.

Advantages of planting water spinach: it grows fast. Water spinach is fond of water. Water spinach naturally grows very fast in such a watery environment, and its yield will be higher.

Disadvantages of planting water spinach: easy to be polluted. Small-scale planting is ok. If it is planted professionally, the water quality is poor, and many toxic and harmful substances will be adsorbed. It's not easy to pick. It's more troublesome to grow water spinach in water, but it's much simpler in dry land.

Water spinach can be divided into two categories: xerophytic and aquatic. Dry-grown seeds are cultivated in dry land, and there are many flowers and seeds, including safflower and white flower. White-flowered seeds are of good quality and high yield. Ipomoea aquatica is a vine, which is mostly planted in paddy fields. Its quality is better than that of seed, its growth period is long, its yield is high, its flowering is few, and it is more difficult to seed. It is often propagated by vines.
