Expanded Information:

Water chestnut likes to be born in ponds and swamps or cultivated in the paddy fields, likes warmth, loves wetness and is afraid of freezing, and is suitable for growing in loamy soil with loose tillage and solid subsoil.

The cultivation requires a 20-25 cm layer of tillage, which is conducive to the growth and development of the bulb, but does not lead to deep drilling of the bulb, the individual development of the size of the uniformity and consistency, but also conducive to the digging and harvesting.

Tillage layer too sticky, not conducive to bulb expansion, too much humus, bulb sugar content is reduced, sweet taste is poor. Suitable for growth in shallow water, in terms of nutritional requirements, requires less nitrogen fertilizer, more phosphorus fertilizer. Throughout the growing period, sufficient light is required.
