9+ Ways to Use and Preserve Rhubarb

Rhubarb Season

Rhubarb is a perennial plant which means it comes back year after year. The season for it is early to mid-spring through early summer. In the US, rhubarb season is usually around April through July. It is however, often grown as an annual in warmer climates (warmer than zone 8). Learn more about growing, caring for, and harvesting rhubarb with our guide!

The season is short, but rhubarb plants are prolific which makes them great for preserving. You can also eat rhubarb fresh as part of your seasonal eating menu.

Where to Buy Rhubarb

You can buy rhubarb at the Farmer’s market if it grows in your area. Rhubarb can also be found in the produce section of some grocery stores.

Don’t be afraid to buy stems with a green tinge to them. Different varieties of rhubarb will have different shades of red. Look for stems that are around 3/4″ in diameter and at least 7″ long.

If you can’t find fresh rhubarb you might be able to find frozen rhubarb in the frozen section of the grocery store.

Eating Raw Rhubarb

Yes, you can even eat rhubarb raw….just remember that it’s quite tart. However, dipped in sugar or another sweetener it makes a tasty snack.

When people talk about eating rhubarb they are talking about eating just the rib or stem of the rhubarb plant. Not the green leaf. The leaves are toxic and can cause all kinds of trouble for you. You can learn about the toxicity of rhubarb leaves in the article from Oregon State University. The leaves can be added to your compost.

How to Prepare Rhubarb for Preserving

Here’s how to prepare rhubarb for eating…

  1. Remove the green leafy part from the stem and discard (do not feed this to chickens or other livestock. Compost instead)
  2. Cut the end of stems off and compost them
  3. Remove any brown spots or tough strings with a vegetable peeler or knife
  4. Rinse the rhubarb stalks in cold water
  5. Slice the stalks crosswise into 1-2″ sections. Rhubarb cooks down quite a bit so usually isn’t cut into super small pieces

Rhubarb Juice

There are a couple methods of making “rhubarb juice.” One is to boil pieces of rhubarb in water with some sugar to extract the flavor and to sweeten it. Another is to simply put it through a juicer in 4 to 5 inch long pieces. Due to its fibrous nature, you’ll have to clean out the juicer blades after four or five stalks. Cutting rhubarb into 1-inch pieces and then freezing it first will give you more yield when you then put it through a juicer. This makes a very tasty lemonade!

  2. Cut the rhubarb stems into bite size pieces
  3. Fill a quart size freezer bag
  4. Squeeze all the air out and close the bag
  5. Label the bag with the contents and date
  6. Put the bag in the freezer

You can also use a vacuum sealer to freeze rhubarb, which will keep it fresher than using Ziplock bags.

Use frozen rhubarb within a year.

This is my third year growing rhubarb,love the plant. I read the information on harvesting it and am wondering how thin can it be to harvest? I have stalks that are 12-14 inches long but only as wide as a drinking straw, should I harvest these or leave them

Are they completely red? For me it would depend on what they’re being used for. Canning, cooking down, sure- you’ll just need more. For pies and such, I prefer to use at least 1” thick stalks.

When using frozen rhubarb should I put it in a strainer or thaw it in a bowl using all the juices? Then when making a pie add extra flour?

If it ends up with a lot of liquid, I would set some of it aside and definitely try adding a bit of flour. Personally, I love adding rhubarb juice to my lemonade!
