How Do You Harvest Rhubarb: Tips and Methods
How Do You Harvest Rhubarb?
To harvest rhubarb, you should twist and pull the stalk from the bottom of the plant, rather than cutting it off with a knife.
If the stalk doesn’t come away immediately, try twisting and pulling in the other direction or pack the plant more firmly into the soil.
Make sure to remove the leaves as only the stalks are edible.
The color of the stalk does not indicate readiness, but the length should ideally be between 7 and 15 inches.

Did You Know?
1. Rhubarb is not technically a fruit, but a vegetable. Although commonly used in sweet dishes, such as pies and jams, rhubarb is classified as a vegetable because it is the stalk of a plant.
2. The leaves of the rhubarb plant are highly toxic and should never be consumed. They contain a poisonous compound called oxalic acid, which can cause serious health problems if ingested in large quantities.
3. Rhubarb is believed to have originated in China over 5,000 years ago. It was initially cultivated for its medicinal properties before it became popular as a food ingredient.
4. The bright red color of some rhubarb stalks is due to their high concentration of anthocyanins, a type of pigment commonly found in fruits and vegetables. However, not all varieties of rhubarb have red stalks; some can be green or pinkish.
5. Rhubarb is considered a “cool-season” crop and is one of the first plants to be harvested in the spring. It thrives in colder climates and its growth is often stimulated by frost, which helps develop its distinctive tart flavor.
The Best Technique For Harvesting Rhubarb
When it comes to harvesting rhubarb, many people may reach for a knife to cut off the stalks. However, this is not the best way to harvest rhubarb. The most effective technique involves twisting and pulling the stalk from the bottom of the plant. By using this method, you allow for regrowth and ensure the health and longevity of your plant.
How To Properly Harvest Rhubarb Stalks
To harvest rhubarb stalks using the twist and pull method, first, you need to find a ready stalk. Look for stalks that are thick and firm. Then, grasp the stalk near the bottom and gently twist it while pulling upwards. The stalk should come away easily from the plant. If it doesn’t, try twisting and pulling in the other direction or pack the plant more firmly into the soil for better stability.
Once you have successfully harvested the stalks, it’s important to remove the leaves. Rhubarb leaves contain toxic substances and should never be consumed. Only the stalks are edible, so make sure to discard the leaves properly.
Determining The Readiness Of Rhubarb Stalks For Harvest
Contrary to popular belief, the color of the rhubarb stalks does not indicate their readiness for harvest. Instead, the length of the stalks is a better indicator. The ideal length for harvesting rhubarb stalks is between 7 to 15 inches. Stalks within this range are typically mature, tender, and flavorful.
The best time to harvest rhubarb is from May to early July, when the stalks are at their peak. It’s important to avoid harvesting rhubarb too late in the season, as the stalks may become tough and stringy. By harvesting during this optimal period, you can enjoy the best flavor and texture that rhubarb has to offer.
Tips For Extending The Rhubarb Harvest Season
To extend the rhubarb harvest season, there are several techniques that can be utilized:
-
Cutting the flower stalk: By removing the flower stalk before it blooms, the plant’s energy is redirected towards producing more edible stalks. This helps to extend the harvest season significantly.
-
Leaving some stalks behind: Instead of removing all the stalks, it is advisable to leave at least one-third of the plant intact. This allows the plant to regenerate and continue growing, ensuring a sustainable and bountiful harvest in the future.
These two techniques can greatly enhance the rhubarb harvest season, providing a longer and more abundant yield.
- Cutting the flower stalk before it blooms
- Leaving some stalks behind for regeneration
Important Guidelines For Sustainable Rhubarb Harvesting
To ensure the sustainability of your rhubarb plant, follow these guidelines:
-
Practice responsible harvesting: Do not remove more than two-thirds of the plant at one time. This allows for the plant to recover and produce for subsequent seasons.
-
Pay attention to the overall health of your rhubarb plant: Regularly monitor and control pests and diseases that might affect the growth and productivity. By maintaining a healthy environment, you can continue to enjoy its delicious stalks for years to come.
here are some additional tips for harvesting rhubarb:

By employing this method, you minimize the risk of disease and promote the overall health of the plant, ensuring a more productive harvest in the following seasons.
Can you eat rhubarb leaves?
Yes, it is advised to avoid eating rhubarb leaves due to their toxicity. Rhubarb leaves contain harmful chemicals that can be toxic to both humans and animals. Although one would need to consume a significant amount to experience severe illness, it is recommended to exercise caution and refrain from consuming them altogether.
Is green rhubarb safe to eat?
Yes, green rhubarb is safe to eat. In fact, it can be just as delicious as the more common red-stemmed varieties.
