As summer transitions into autumn, gardeners and cooking enthusiasts alike often wonder about the optimal time for harvesting rhubarb. Rhubarb, a versatile and tart ingredient, is commonly used in pies, tarts, and jams. However, its harvesting period is crucial for maintaining the plant’s health and ensuring a bountiful yield the following year. The question of whether one can still pull rhubarb in September is multifaceted, involving considerations of climate, plant care, and the specifics of rhubarb cultivation. This article delves into the world of rhubarb, exploring the best practices for its care and the feasibility of a September harvest.
Understanding Rhubarb Basics
Before diving into the specifics of September harvesting, it’s essential to understand the basics of rhubarb. Rhubarb is a perennial plant that thrives in cooler climates. It is known for its edible stalks, which are often paired with sweet ingredients like strawberries to balance out their tartness. The leaves of the rhubarb plant, however, are toxic due to their high oxalic acid content and should never be consumed.
Climatic Considerations
Rhubarb grows best in areas with cold winters and cool, moist summers. The plant requires a period of frost to break dormancy, which is why it is typically planted in the fall or early spring. In regions with mild winters, rhubarb may not receive the necessary chill hours to produce a healthy crop, potentially affecting its growth cycle and, by extension, its harvesting period.
Regional Variations
The feasibility of pulling rhubarb in September largely depends on your geographical location. In areas with an early fall, such as the Northeastern United States or parts of Northern Europe, the first frosts may occur as early as late August or September. This could potentially damage the rhubarb plant, signaling the end of the harvesting season. Conversely, in regions with a later fall, such as the Western United States or parts of Southern Europe, the harvesting period may extend well into September or even October.
The Harvesting Season
The traditional harvesting season for rhubarb is from late spring to early summer, typically starting in April or May and ending by June or July, depending on the climate and variety. During this period, the stalks are tender and less likely to be bitter. It is crucial not to over-harvest rhubarb, as this can weaken the plant, reducing its yield and potentially killing it. The general rule of thumb is to harvest stalks when they are between 10 to 15 inches long, leaving the smaller stalks to continue growing.
September Harvest Considerations
While the primary harvesting season for rhubarb is in the spring, there are instances where pulling rhubarb in September might be possible. This could occur in regions with a late-summer or early-fall resurgence of growth, prompted by cooler temperatures and increased moisture. However, any stalks harvested in September should be carefully selected, choosing only those that are still tender and avoiding any that may be woody or bitter.
Forcing Rhubarb
Another approach to consider for a September harvest is forcing rhubarb. This involves covering the crowns of the plant with a layer of straw or a forcing pot in late winter to early spring, which tricks the plant into believing it is time to grow. Forcing can result in an earlier-than-usual harvest, but it also means that the plant may be exhausted by the time September arrives, making a late harvest less viable.
Caring for Rhubarb Plants
To ensure a healthy rhubarb plant capable of producing well into the season and potentially even offering a September harvest, proper care is essential. This includes adequate watering, especially during dry spells, and fertilizing the soil around the plant annually. Additionally, dividing and replanting the rhubarb every 5 to 10 years can help maintain its vigor and productivity.
Maintenance Tasks
Regular maintenance tasks are vital for the health and longevity of the rhubarb plant. This includes removing any dead or dying stalks and not allowing the plant to seed, as this can divert energy away from stalk production. Furthermore, monitoring for pests and diseases and taking prompt action if any issues are spotted can prevent damage to the plant.
Preparation for Winter
As September progresses and the weather cools, it’s essential to prepare the rhubarb plant for the winter ahead. This involves cutting back the stalks after the first frost and applying a layer of mulch or compost to protect the crown and retain moisture in the soil. These steps help the plant survive the cold months and emerge healthy and ready to produce in the spring.
Conclusion
While the primary rhubarb harvesting season is in the spring, pulling rhubarb in September is not entirely out of the question. It depends on various factors, including your location, the specific variety of rhubarb, and how well the plant has been cared for throughout the growing season. By understanding the needs of the rhubarb plant and following best practices for its care, gardeners can potentially enjoy a longer harvesting period. Remember, the key to successful rhubarb cultivation is patience, proper care, and a deep understanding of the plant’s unique requirements and growth patterns.

Can I Still Pull Rhubarb in September?
Rhubarb is typically considered a spring crop, with the peak harvest season occurring between late March and early July, depending on the variety and climate. However, some gardeners may be able to continue harvesting rhubarb into the summer and even early fall months, including September, if the plants are well-cared for and the weather conditions are favorable. It’s essential to note that the quality and flavor of the rhubarb may decline as the season progresses, and the stalks may become tougher and more fibrous.
To determine if your rhubarb is still suitable for harvesting in September, inspect the plants for any signs of decline, such as yellowing leaves or soft, mushy stalks. If the rhubarb appears healthy and vigorous, you can continue to harvest it, but be sure to only pull the tallest, most tender stalks, and avoid damaging the crown or disturbing the roots. It’s also crucial to maintain a consistent watering schedule and provide the plants with adequate nutrients to support continued growth and productivity. By doing so, you may be able to extend the rhubarb harvest season and enjoy this delicious and versatile vegetable for a longer period.
How Often Can I Pull Rhubarb Stalks?
The frequency of pulling rhubarb stalks depends on various factors, including the age and health of the plants, as well as the desired yield and quality. As a general rule, it’s recommended to pull no more than one-third to one-half of the stalks from each plant at any given time, allowing the remaining stalks to continue growing and replenishing the plant’s energy reserves. This approach helps to prevent exhausting the plants and ensures a consistent supply of fresh, tender rhubarb throughout the harvest season.
It’s also important to consider the stage of growth and development when pulling rhubarb stalks. For example, during the peak harvest season, you may be able to pull stalks every 1-2 weeks, as the plants are producing new growth rapidly. However, as the season progresses and the plants begin to slow down, you may need to reduce the frequency of pulling to every 3-4 weeks, or even less often, to avoid depleting the plants’ resources. By monitoring the plants’ growth and adjusting your harvesting schedule accordingly, you can enjoy a bountiful and prolonged rhubarb harvest.
Will Pulling Rhubarb Stalks Hurt the Plant?
Pulling rhubarb stalks is a common harvesting method, and when done correctly, it should not harm the plant. In fact, regular harvesting can help to promote healthy growth and encourage the plant to produce new stalks. However, it’s essential to pull the stalks gently and carefully, avoiding any sudden or excessive force that could damage the crown or disturb the roots. It’s also important to only pull the stalks that are ready for harvest, leaving any immature or soft stalks to continue growing and developing.
To pull rhubarb stalks without harming the plant, grasp the stalk near the base, where it meets the crown, and gently twist it while pulling it away from the plant. This helps to break the stalk free from the crown without causing damage to the roots or surrounding tissue. It’s also crucial to avoid pulling too many stalks from a single plant, as this can weaken the plant and reduce its ability to produce new growth. By pulling rhubarb stalks carefully and selectively, you can enjoy a bountiful harvest while also preserving the health and productivity of your rhubarb plants.
How Do I Know When Rhubarb is Ready to Harvest?
Rhubarb is typically ready to harvest when the stalks have reached a length of 10-12 inches and are about 1 inch in diameter. The stalks should be firm, crisp, and have a deep red or green color, depending on the variety. Avoid pulling stalks that are too small or immature, as they may be too tart or fibrous. It’s also important to inspect the stalks for any signs of damage or disease, such as soft spots, mold, or insect infestations, and to discard any affected stalks to prevent the spread of disease.
In addition to checking the size and appearance of the stalks, you can also monitor the plants’ growth cycle to determine when they are ready for harvest. Rhubarb plants typically emerge from dormancy in early spring, and the stalks begin to grow rapidly as the weather warms up. As the plants reach their peak growth, the stalks will begin to mature and become ready for harvest. By observing the plants’ growth cycle and checking the stalks regularly, you can determine the optimal time for harvesting and enjoy a bountiful and flavorful crop of rhubarb.
Can I Grow Rhubarb in Containers?
Yes, rhubarb can be grown in containers, provided that the containers are large enough to accommodate the plants’ extensive root system and deep taproots. A minimum container size of 12-18 inches deep and 24-36 inches wide is recommended, with good drainage holes to prevent waterlogged soil. It’s also essential to use a well-draining potting mix and to maintain a consistent watering schedule to support healthy growth and productivity.
When growing rhubarb in containers, it’s crucial to provide the plants with full sun to partial shade and to fertilize them regularly to promote healthy growth. You can also prune the plants regularly to maintain a compact shape and encourage bushy growth. Keep in mind that container-grown rhubarb may require more frequent watering and fertilization than plants grown in the ground, as the soil can dry out quickly and may not provide the same level of nutrients. By providing the right conditions and care, you can enjoy a thriving and productive container-grown rhubarb plant.
How Do I Store Fresh Rhubarb?
Fresh rhubarb can be stored in the refrigerator to keep it fresh for several days. To store rhubarb, trim the stalks to remove any leaves or damaged areas, and place them in a sealed plastic bag or airtight container. Keep the rhubarb away from direct sunlight and moisture, and maintain a consistent refrigerator temperature between 32°F and 40°F. You can also wrap the rhubarb stalks in damp paper towels or cloth to help maintain humidity and keep them fresh for a longer period.
For longer-term storage, you can also consider freezing or canning rhubarb. To freeze rhubarb, chop the stalks into small pieces and blanch them in boiling water for 1-2 minutes to inactivate the enzymes. Then, package the blanched rhubarb in airtight containers or freezer bags and store it in the freezer at 0°F or below. Canning rhubarb involves cooking the stalks in a sugar syrup and then sealing them in sterilized jars. By following safe canning practices, you can enjoy your homegrown rhubarb year-round and preserve its flavor and nutritional value.
