Are you growing green beans in South Dakota, but don’t know when the best time to harvest them is?
Harvesting green beans is not as easy as it seems.
- Green Beans 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 green beans in South Dakota:

When Do I Harvest Green Beans in South Dakota?
As you may have already guessed, there are two main factors that determine when you should harvest your green beans: the physical features of the green beans & weather (time).
Harvest Green Beans if They Look Like This!!!
The physical features of green beans 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 green beans if they have the following physical features:
- The entire green beans is a solid red color. If the green beans is a lighter shade of red, it is not ready to be harvested
- The green beans is slightly soft. Too hard means it is not ready. Too soft means it is overripe (but still edible)
- Easily able to be deattached from the the plant. This means it has absorbed all the nutrients it needs and is ready.
Harvest Your Green Beans During THIS Time of Year!!!
In general, you should harvest green beans:
- 65 to 85 days after starting green beans from seed
- 40 to 50 days after planting green beans in your garden
- 20 to 30 days after green beans first appear
And no matter what, you should ALWAYS harvest your green beans before the first frost of the year. Frost will immediately kill your green beans plant and make your green beans inedible.
For your reference, I have created this table for average frost dates for most major cities in South Dakota. If your city is not listed below you can find its Last & First Frost Dates HERE.
South Dakota 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 green beans are in pots, bring them inside
- If green beans are in the ground, cover them in burlap and hope they survive
- Pick all green beans. If they are not ready, place them in a brown paper bag and store them for approximately 1 to 2 weeks to see if they become edible.
