Here is the BEST Time to Harvest Asparagus in Ohio (2023 Guide)

Are you growing asparagus in Ohio, but don’t know when the best time to harvest them is?

Harvesting asparagus is not as easy as it seems.

Here’s why:

  • Asparagus 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 flower and taste sour or become inedible.

Today, I’m going to teach you the ideal time to harvest asparagus in Ohio:

When Do I Harvest Asparagus in Ohio?

As you may have already guessed, there are two main factors that determine when you should harvest your asparagus: the physical features of the asparagus & weather (time).

Harvest Asparagus if They Look Like This!!!


The physical features of asparagus 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 asparagus if they have the following physical features:

  • The height of the asparagus is between 6 – 12 inches. If it is less than 6 inches it isn’t ready and if it is more than 12 inches it won’t taste good.
  • The asparagus is tender to the touch. If it is tough to the touch is means it is overripe and will not taste good or is inedible.
  • Depending on the asparagus plant you grow the asparagus will be green, purple, or white.

Harvest Your Asparagus During THIS Time of Year!!!

In general, you should harvest asparagus:

  • 85 to 100 days after starting asparagus from seed
  • 40 to 50 days after planting asparagus in your garden

And no matter what, you should ALWAYS harvest your asparagus before the first frost of the year. Frost will immediately kill your asparagus plant and make your asparagus 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.

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 asparagus are in pots, bring them inside
  • If asparagus are in the ground, cover them in burlap and hope they survive
  • Pick all asparagus. Asparagus are perennial vegetables, so they will always come back and you don’t have to worry about the plant dying.
