As summer begins to fade and the days grow shorter, many gardeners wonder if they can still pick rhubarb in September. Rhubarb, a popular ingredient in pies, tarts, and jams, is typically associated with springtime harvesting. However, with the right conditions and care, it is possible to extend the rhubarb harvesting season into early fall. In this article, we will delve into the world of rhubarb, exploring its growth habits, harvesting techniques, and the factors that influence its availability in September.
Understanding Rhubarb Growth and Development
Rhubarb is a perennial plant that thrives in cool, temperate climates. It belongs to the Polygonaceae family and is native to Asia. Rhubarb plants consist of large, leafy greens and tart, edible stalks that are rich in vitamins and minerals. The plant’s growth cycle is characterized by a period of dormancy during the winter months, followed by a rapid growth spurt in early spring.
Rhubarb Plant Life Cycle
The rhubarb plant life cycle can be divided into several stages:
The plant emerges from dormancy in early spring, typically around late March or early April, and begins to produce new growth.
As the weather warms up, the plant focuses its energy on producing large, leafy greens and stalks.
In late spring and early summer, the plant reaches its peak growth and is ready for harvesting.
After the initial harvest, the plant may produce secondary growth, including smaller stalks and leaves.
In the fall, the plant prepares for dormancy by storing energy in its roots and crowns.
Factors Influencing Rhubarb Availability in September
Several factors can influence the availability of rhubarb in September, including:
- Climate and Weather Conditions: Rhubarb plants thrive in cool, temperate climates with moderate temperatures and adequate moisture. Extreme weather conditions, such as heatwaves or droughts, can impact the plant’s growth and availability.

By understanding the rhubarb plant life cycle, factors that influence its availability, and using the right harvesting techniques, gardeners can enjoy a bountiful harvest of delicious, tart rhubarb stalks well into the fall season. Whether you are a seasoned gardener or just starting out, with the right knowledge and care, you can enjoy the many benefits of growing and harvesting rhubarb, including its unique flavor, nutritional value, and versatility in a variety of recipes.
Can I Still Pick Rhubarb in September?
Picking rhubarb in September is generally not recommended, as the plant is typically ready for a period of dormancy after the summer months. Rhubarb is a cool-season crop that thrives in the spring and early summer, and by September, the stalks may have become tough and less flavorful. Additionally, allowing the plant to go dormant during the fall and winter months is essential for its health and productivity in the following year. During this time, the plant stores energy in its roots, which is necessary for producing new stalks and leaves in the spring.
However, if you live in a region with a mild climate, you may still be able to pick some rhubarb in September, especially if you have a variety that is known to produce stalks later in the season. It’s essential to check the condition of the stalks before harvesting, as they should be tender and have a good flavor. If the stalks are tough or bitter, it’s best to wait until the following spring when the plant is producing new growth. It’s also important to note that over-harvesting in the fall can weaken the plant and reduce its productivity in the following year, so it’s crucial to harvest only what you need and leave some stalks to allow the plant to store energy for the next growing season.
How Do I Know When Rhubarb is Ready to Harvest?
Rhubarb is typically ready to harvest in the spring, about 8 to 10 weeks after the plants emerge from the ground. The stalks should be around 10 to 12 inches long and about 1 inch thick, with a deep red or green color, depending on the variety. The leaves should be fully expanded and have a glossy appearance. It’s essential to check the stalks regularly, as they can quickly become too mature and develop a bitter flavor. You can also check the plant’s crown, which should be firm and compact, with new growth emerging from the center.
When harvesting rhubarb, it’s crucial to avoid pulling on the stalks, as this can damage the plant’s crown and reduce its productivity. Instead, grasp the stalk near the base and twist it gently, which should cause it to come away from the plant easily. You can also use a sharp knife or pair of scissors to cut the stalks at the base, leaving about an inch of stem attached to the plant. This will help to prevent the plant from becoming weakened and will also encourage new growth to emerge. By harvesting rhubarb at the right time and using the correct technique, you can enjoy a bountiful and delicious crop.
Can I Harvest Rhubarb in the Fall?
While it’s technically possible to harvest rhubarb in the fall, it’s not usually recommended. Rhubarb is a cool-season crop that thrives in the spring and early summer, and by the fall, the stalks may have become tough and less flavorful. Additionally, allowing the plant to go dormant during the fall and winter months is essential for its health and productivity in the following year. During this time, the plant stores energy in its roots, which is necessary for producing new stalks and leaves in the spring. Harvesting in the fall can weaken the plant and reduce its productivity in the following year.
However, if you have a variety of rhubarb that is known to produce stalks later in the season, you may be able to harvest some in the fall. It’s essential to check the condition of the stalks before harvesting, as they should be tender and have a good flavor. If the stalks are tough or bitter, it’s best to wait until the following spring when the plant is producing new growth. It’s also important to note that over-harvesting in the fall can weaken the plant and reduce its productivity in the following year, so it’s crucial to harvest only what you need and leave some stalks to allow the plant to store energy for the next growing season.
