Are you growing watercress in Ohio, but don’t know when the best time to harvest them is?
Harvesting watercress is not as easy as it seems.
- Watercress have a very short window when they can be harvested and still taste great.
So if you harvest them too early they may not be ready and taste bad. And if you harvest them too late they may become infected with mold, fungus, insects, etc., and become inedible.
Today, I’m going to teach you the ideal time to harvest watercress in Ohio:

When Do I Harvest Watercress in Ohio?
As you may have already guessed, there are two main factors that determine when you should harvest your Watercress: the physical features of the watercress & weather (time).
Harvest Watercress if They Look Like This!!!
The physical features of watercress are what most gardeners commonly rely on to determine if they are ready to be picked off the plant or not.
In general, you should harvest watercress if they have the following physical features:
- The leaves of the watercress are small, short, and light green in color.
- The watercress leaves are soft to the touch and are close together.
Harvest Your Watercress During THIS Time of Year!!!
In general, you should harvest watercress:
- 21 days after starting watercress from seed
- 5 days after planting watercress in your garden
And no matter what, you should ALWAYS harvest your watercress before the first frost of the year. Frost will immediately kill your scallion plant and make your watercress inedible.
For your reference, I have created this table for average frost dates for most major cities in Ohio. If your city is not listed below you can find its Last & First Frost Dates HERE.
Ohio Last & First Frost Dates
It should be noted that you should not overly rely on the first frost of the year. The average first frost of the year is only correct 30% of the time.
Instead, pay close attention to your local weather.
When you know a frost is coming you need to take action.
- If watercress are in pots, bring them inside
- If watercress are in the ground, cover them in burlap and hope they survive
- Pick all watercress.
