Rhubarb is a popular vegetable often used in pies, tarts, and jams, but its unique characteristics and growth patterns have led to confusion about when it can be harvested. While some gardeners swear by pulling rhubarb stalks throughout the year, others claim that this practice can harm the plant. In this article, we will delve into the world of rhubarb cultivation and explore the best practices for harvesting this delicious vegetable.
Understanding Rhubarb’s Growth Cycle
To determine whether rhubarb can be pulled all year, it’s essential to understand its growth cycle. Rhubarb is a perennial plant that typically grows in zones 3-8, where the winters are cold enough to induce dormancy. The plant’s growth cycle can be divided into three stages:
Stage 1: Dormancy (Winter)
During the winter months, rhubarb plants go dormant, and the stalks die back. This period is crucial for the plant’s survival, as it allows the roots to recharge and prepare for the next growing season.
Stage 2: Active Growth (Spring)
As the weather warms up in the spring, rhubarb plants begin to grow new stalks. This is the best time to harvest rhubarb, as the stalks are tender and flavorful. The plant will continue to produce new stalks throughout the spring and early summer.
Stage 3: Seed Production (Summer)
As the summer months approach, rhubarb plants begin to produce seeds. This is a sign that the plant is mature and ready to reproduce. However, seed production can divert energy away from stalk production, making the stalks less tender and flavorful.
Can You Pull Rhubarb All Year?
Now that we understand rhubarb’s growth cycle, let’s address the question of whether it can be pulled all year. The answer is a bit complicated.
While it is technically possible to pull rhubarb stalks throughout the year, it’s not always recommended. Pulling stalks during the dormant season (winter) can damage the plant’s roots and reduce its chances of survival. Similarly, pulling stalks during the seed production stage (summer) can divert energy away from stalk production and reduce the plant’s overall yield.
However, there is a period during the active growth stage (spring) when rhubarb can be pulled without harming the plant. In fact, regular harvesting during this period can encourage the plant to produce more stalks.
The Art of Pulling Rhubarb
Pulling rhubarb is an art that requires some finesse. Here are a few tips to keep in mind:
- Only pull stalks that are at least 12-18 inches long. This will ensure that the stalks are mature and flavorful.
- Grasp the stalk at the base and twist it gently. This will help to avoid damaging the plant’s roots.
- Only pull a few stalks at a time. Over-harvesting can stress the plant and reduce its overall yield.
Rhubarb Varieties and Their Harvesting Periods
Different rhubarb varieties have different harvesting periods. Some popular varieties include:
- ‘Canada Red’: This variety is known for its bright red stalks and can be harvested from late March to early July.
- ‘Valentine’: This variety has bright red stalks with a sweet flavor and can be harvested from late March to early June.
- ‘Victoria’: This variety has green stalks with a tart flavor and can be harvested from late April to early July.

Conclusion
While it is possible to pull rhubarb stalks throughout the year, it’s essential to understand the plant’s growth cycle and harvesting periods to avoid damaging the plant. By following the tips outlined in this article and choosing the right variety for your climate, you can enjoy a bountiful harvest of delicious rhubarb stalks.
Final Tips for Growing Rhubarb
- Plant rhubarb in well-draining soil with a pH between 6.0 and 6.5.
- Water rhubarb regularly, but avoid overwatering.
- Fertilize rhubarb in the spring with a balanced fertilizer.
- Divide and replant rhubarb every 5-7 years to maintain its productivity.
Can You Pull Rhubarb All Year?
You can pull rhubarb during its growing season, but it’s not recommended to do so all year round. Rhubarb is typically ready to harvest in early spring, around late March to early May, depending on your location and climate. During this time, the stalks are tender and sweet, making them perfect for pies, jams, and other desserts.
However, pulling rhubarb outside of its growing season can be detrimental to the plant’s health. Rhubarb needs time to rest and recharge during the winter months, and constant harvesting can weaken the plant. Additionally, pulling rhubarb during the summer months can cause the plant to become stressed, leading to a decrease in its overall productivity.
What Happens If I Pull Rhubarb in the Summer?
Pulling rhubarb in the summer can cause the plant to become stressed, leading to a decrease in its overall productivity. Rhubarb plants need time to focus their energy on growing and developing new stalks, and constant harvesting can disrupt this process. Additionally, summer-pulled rhubarb may be more bitter and fibrous than spring-pulled rhubarb, making it less desirable for cooking and baking.
It’s also worth noting that pulling rhubarb in the summer can make the plant more susceptible to disease and pests. Rhubarb plants are more vulnerable to disease and pests during the summer months, and constant harvesting can weaken the plant’s natural defenses. To avoid these problems, it’s best to limit your rhubarb harvesting to the spring months when the plant is at its peak.
How Often Can I Pull Rhubarb?
The frequency at which you can pull rhubarb depends on the size and health of the plant. As a general rule, you can pull one-third to one-half of the stalks from a mature rhubarb plant at a time. This will give the plant enough time to recover and regrow new stalks. It’s also important to only pull the largest and most tender stalks, leaving the smaller stalks to grow and develop.
It’s also worth noting that you should only pull rhubarb stalks when they are at least 10-12 inches long. Pulling smaller stalks can damage the plant and reduce its overall productivity. Additionally, be sure to pull the stalks gently, twisting them slightly as you pull to avoid damaging the plant’s crown.
Can I Pull Rhubarb in the Fall?
While it’s technically possible to pull rhubarb in the fall, it’s not recommended. Rhubarb plants need time to prepare for the winter months, and constant harvesting can weaken the plant. Additionally, fall-pulled rhubarb may be more bitter and fibrous than spring-pulled rhubarb, making it less desirable for cooking and baking.
It’s also worth noting that pulling rhubarb in the fall can make the plant more susceptible to disease and pests. Rhubarb plants are more vulnerable to disease and pests during the fall months, and constant harvesting can weaken the plant’s natural defenses. To avoid these problems, it’s best to limit your rhubarb harvesting to the spring months when the plant is at its peak.
What Are the Benefits of Pulling Rhubarb in the Spring?
Pulling rhubarb in the spring has several benefits. For one, the stalks are typically sweeter and more tender during this time, making them perfect for pies, jams, and other desserts. Additionally, spring-pulled rhubarb is less likely to be bitter and fibrous, making it more desirable for cooking and baking.
Another benefit of pulling rhubarb in the spring is that it allows the plant to focus its energy on growing and developing new stalks. By limiting your harvesting to the spring months, you can help promote healthy growth and development in your rhubarb plant. This will lead to a more productive plant that will provide you with delicious stalks for years to come.
How Do I Know When Rhubarb Is Ready to Pull?
Rhubarb is typically ready to pull when the stalks are at least 10-12 inches long and about 1 inch in diameter. You can also check for readiness by gently tugging on the stalk. If it comes away from the plant easily, it’s ready to pull. If it resists, it’s not yet ready.
It’s also worth noting that rhubarb is typically ready to pull in the early spring, around late March to early May, depending on your location and climate. During this time, the stalks are tender and sweet, making them perfect for pies, jams, and other desserts. Be sure to check your rhubarb plant regularly during this time to catch the stalks at their peak.
Can I Grow Rhubarb in Containers?
Yes, you can grow rhubarb in containers. In fact, container-grown rhubarb can be a great option for gardeners with limited space. When growing rhubarb in containers, be sure to choose a large enough pot to accommodate the plant’s mature size. Rhubarb plants can grow quite large, so be sure to choose a pot that is at least 12-18 inches deep and 24-36 inches wide.
It’s also worth noting that container-grown rhubarb will require more frequent watering and fertilization than garden-grown rhubarb. Be sure to water your container-grown rhubarb regularly, and fertilize it with a balanced fertilizer in the spring and summer months. With proper care, container-grown rhubarb can thrive and provide you with delicious stalks for years to come.
