Planting Water Chestnut

Water chestnuts grow best in climates with long hot summers. They grow in shallow ponds and are not generally affected by weather extremes. Plant the corms in the spring, after the last frost has passed. Water Chestnuts can be planted in any shallow fresh water environment at 2 to 3 inches deep and 1 foot apart in all directions. Your goal in planting the corms is to insert it into the (underwater) soil, piling soil around it.

You can try using small stones to hold the corm and soil in place. Make sure the corm is covered by a minimum of 4” of dirt and no less than 1” of water. The pH of the soil should be around 7.0. Do not over crowd – the harvest will be reduced.

Harvesting and Storing Water Chestnut

At the end of the season, the stem turns brown and dies back. It's common to harvest during the late fall, for best flavor and the most nutrients. You can harvest in the spring, but since the plant is coming out of dormancy and using it's resources to prepare for growth, you may notice a decrease in flavor and texture. Bring water chestnuts to a boil; drain and peel off shells. Pack water chestnuts in freezer bags, remove air, seal and label; freeze for up to 6 months.
