Are you growing rhubarb in Utah, but don’t know when the best time to harvest them is?
Harvesting rhubarb is not as easy as it seems.
- Rhubarb 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 rhubarb in Utah:

When Do I Harvest Rhubarb in Utah?
As you may have already guessed, there are two main factors that determine when you should harvest your rhubarb: the physical features of the rhubarb & weather (time).
Harvest Rhubarb if They Look Like This!!!
The physical features of rhubarb 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 rhubarb if they have the following physical features:
- The entire rhubarb is a solid red color. If the rhubarb is a lighter shade of red, it is not ready to be harvested
- The rhubarb 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 Rhubarb During THIS Time of Year!!!
In general, you should harvest rhubarb:
- 65 to 85 days after starting rhubarb from seed
- 40 to 50 days after planting rhubarb in your garden
- 20 to 30 days after rhubarb first appear
And no matter what, you should ALWAYS harvest your rhubarb before the first frost of the year. Frost will immediately kill your rhubarb plant and make your rhubarb inedible.
For your reference, I have created this table for average frost dates for most major cities in Utah. If your city is not listed below you can find its Last & First Frost Dates HERE.
Utah 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 rhubarb are in pots, bring them inside
- If rhubarb are in the ground, cover them in burlap and hope they survive
- Pick all rhubarb. 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.
