Growing Water Chestnut
Water chestnuts are an aquatic plant that grows in ponds, marshes, and shallow areas of slow-moving streams and rivers. They are grown for food, with their tasty corms used as vegetables in salads and stir-fries, and their shoots and leaves eaten as a vegetable. They are a great source of fiber, proteins, and minerals and are also used to make medicinal oil, flour, and a sweet drink.

Growing Water Chestnut: A Unique Addition to Your Backyard
Ever thought about adding something exotic to your garden? Consider growing water chestnuts! It's easier than you think, even in a small backyard.
What You'll Need
- Large containers or shallow ponds
- Muck soil or potting mix
- Water chestnut corms
You can find corms at Asian markets or online. I got mine online and they were surprisingly robust by the time they arrived.
Setting Up Your Container
Choose a broad, shallow container. Water chestnuts prefer about 4-6 inches of water above the soil surface.
Fill the bottom with a layer of mucky soil. This can be pond soil or a mix of 1 part clay and 1 part sand.
Water chestnuts thrive best in shallow, stagnant water, making them perfect for home gardeners with minimal space!
Once your container is filled, simply add water. Keep it at a consistent level to avoid stressing the plants.
Planting the Corms
Push the corms about 4 inches deep into the muck. Space them about a foot apart to give them room to grow.
In my experience, it's best to plant water chestnut corms in late spring when the water temperatures are warmer. This promotes faster growth.
Caring for Your Water Chestnuts
Water chestnuts are fairly low-maintenance. They need at least six hours of sunlight daily for optimal growth.
Maintain the water level. You'll find this easy with a larger container as it holds more water and evaporates slower.
Studies show that mature corms provide an impressive yield of up to 7 corms per plant!
Every few weeks, check for pests. I've spotted aphids occasionally, but a gentle water spray usually keeps them in check.
Harvesting the Bounty
Water chestnuts reach maturity in 7-8 months. When the leaves turn yellow, it's harvest time!
Drain the water and gently dig around each plant. Lift the corms, wash them under running water, and they're ready to use.
From stir-fries to salads, fresh water chestnuts offer a crunchy, nutty flavor you won't get from canned ones. Trust me, the taste difference is enormous.
