Do you want to grow Water Chestnuts in Hardiness Zone 3, but don’t know when to plant them?
Planting Water Chestnuts is not as easy as it seems.
Here’s why:
- Water Chestnuts are not able to survive frost or cold weather under 50 degrees Fahrenheit.
So if you plant them outside too early in the spring they will die. And if you plant them too late, your Water Chestnuts won’t produce a harvest before the first frost arrives in the fall.
Today, I’m going to teach you the ideal time to plant Water Chestnuts in Hardiness Zone 3.

When to Plant Water Chestnuts in Hardiness Zone 3
As you may have already guessed, you need to pay very close attention to your local weather in the spring. Specifically, you are going to need to watch when the last frost occurs.
In general, when there hasn’t been a frost for two weeks, you are SAFE to plant your Water Chestnuts outside in Hardiness Zone 3!
Unfortunately, Mother Nature plays cruel tricks on us every year.
There are years when the last frost comes MUCH later. Sometimes, the last frost happens much earlier and you can get your Water Chestnuts planted outside in Hardiness Zone 3 much quicker.
Like I said before, you need to be very diligent in checking your local weather.
So what happens if a frost comes AFTER you plant your Water Chestnuts?
When you know a frost is coming you need to take action.
- If Water Chestnuts are in pots, bring them inside
- If Water Chestnuts are in the ground, cover them in burlap and hope they survive
Also, make sure not to plant your Water Chestnuts in your garden too late.
- Planting Water Chestnuts too late will cause small Water Chestnuts or even worse, no Water Chestnuts.
When Should You Start Your Water Chestnut Seeds Indoors?
Depending on the type of Water Chestnut, it takes roughly 210-240 days to grow Water Chestnuts from seed indoors and then transplant them to your garden.
For a specific date that you should start Water Chestnut seeds indoors you should:
- Find the last average frost date HERE
- And then subtract 240 days from it
Not only this, but I recommend again paying close attention to your local weather report.
It should also be noted that the best technique for bringing your Water Chestnut plants outside is to introduce them (in their pots) outside for an hour. And then increase the amount of time they spend outside each day by an hour until they have been outside for 8 hours.
This will “hardened” your Water Chestnut plant, increasing its chances of fighting off diseases, insects, droughts, and wet conditions.
