As the summer months come to a close, many gardeners are left wondering if they can still enjoy their rhubarb plants in September. Rhubarb is typically associated with springtime, when its tart stalks are at their peak flavor and texture. However, with proper care and attention, it is possible to harvest and eat rhubarb in September.
Understanding Rhubarb’s Growth Cycle
To determine if you can harvest rhubarb in September, it’s essential to understand the plant’s growth cycle. Rhubarb is a perennial vegetable that grows from crowns, which are underground stems that produce new growth each year. In the spring, rhubarb plants produce new stalks, which are the edible part of the plant. These stalks grow rapidly, and by early summer, they begin to fade and die back.
During the summer months, rhubarb plants focus their energy on producing flowers and seeds. This process, called bolting, can weaken the plant and reduce its productivity. To encourage healthy growth and prevent bolting, it’s crucial to remove any flower stalks that appear during the summer.
Forcing a Second Crop
While rhubarb plants typically produce one main crop in the spring, it is possible to force a second crop in the fall. This process, called “forcing,” involves covering the plant with a container or mulch to simulate winter conditions. By doing so, you can trick the plant into producing new growth, which can be harvested in the fall.
To force a second crop, start by removing any dead or dying stalks from the plant. Then, cover the plant with a container or a thick layer of mulch. This will help to simulate winter conditions and encourage the plant to produce new growth. Leave the container or mulch in place for 4-6 weeks, or until you see new stalks emerging.
Harvesting Rhubarb in September
If you’ve forced a second crop or have a variety of rhubarb that is known to produce a fall crop, you can harvest the stalks in September. When harvesting rhubarb, it’s essential to follow a few simple guidelines to ensure the plant remains healthy and productive.
- Only harvest stalks that are at least 12-18 inches long. This will help to prevent damaging the plant and ensure that you get the best flavor and texture.
- Use a sharp knife or pair of scissors to cut the stalks. This will help to prevent bruising the plant and make it easier to harvest.
- Harvest stalks in the morning, when they are at their most tender. This will help to ensure that you get the best flavor and texture.
Using Rhubarb in Fall Recipes
Rhubarb is a versatile ingredient that can be used in a variety of fall recipes. From pies and tarts to soups and stews, rhubarb adds a unique flavor and texture that is perfect for the season. Here are a few ideas for using rhubarb in your fall cooking:
- Rhubarb Apple Crisp: Combine fresh rhubarb and apples with sugar, flour, and spices, and top with a crunchy oat topping.
- Rhubarb and Ginger Soup: Simmer fresh rhubarb and ginger in a flavorful broth, then puree until smooth.
- Rhubarb and Pear Tart: Arrange fresh rhubarb and pears in a tart shell, then top with a crumbly pastry crust.
Common Challenges When Harvesting Rhubarb in September
While harvesting rhubarb in September can be a rewarding experience, there are a few common challenges to be aware of. Here are a few things to keep in mind:
- Reduced flavor and texture: Rhubarb harvested in September may not have the same flavor and texture as stalks harvested in the spring. This is because the plant’s energy is focused on producing flowers and seeds, rather than edible stalks.
- Increased risk of disease: Rhubarb plants are more susceptible to disease in the fall, when the weather is cooler and wetter. To minimize the risk of disease, make sure to remove any dead or dying stalks, and avoid harvesting stalks that are damaged or diseased.
- Shorter harvest season: The harvest season for fall rhubarb is typically shorter than the spring harvest season. This means that you’ll need to be prepared to harvest the stalks quickly, before they fade and die back.
Tips for a Successful Fall Harvest
To ensure a successful fall harvest, follow these tips:
- Choose a variety of rhubarb that is known to produce a fall crop. Some popular varieties include ‘Canada Red’ and ‘Valentine’.
- Provide the plant with plenty of moisture and nutrients. This will help to encourage healthy growth and prevent disease.
- Monitor the plant regularly for signs of disease or pests. This will help to minimize the risk of damage and ensure a healthy harvest.

Can I Harvest Rhubarb in September?
You can harvest rhubarb in September, but it depends on the specific variety and growing conditions. Some rhubarb varieties are bred for a fall harvest, while others are best picked in the spring. If you’re unsure, check the specific growing instructions for your rhubarb plant.
In general, rhubarb is ready to harvest when the stalks are around 12-18 inches long and about 1 inch thick. You can also check for readiness by gently tugging on a stalk. If it comes off the plant easily, it’s ready to harvest. Be sure to only harvest the stalks, as the leaves contain high levels of oxalic acid and are toxic.
How Do I Harvest Rhubarb in the Fall?
To harvest rhubarb in the fall, simply grasp the stalk at the base and twist it gently. This will help to loosen the stalk from the plant, making it easier to remove. You can also use a sharp knife or pruning shears to cut the stalk at the base, but be careful not to damage the crown of the plant.
It’s also important to only harvest a few stalks at a time, as over-harvesting can weaken the plant. Leave at least 2-3 stalks on the plant to allow it to continue growing and storing energy for next year’s harvest. You can also consider dividing and replanting your rhubarb in the fall to encourage new growth.
What Are the Benefits of a Fall Rhubarb Harvest?
A fall rhubarb harvest can be beneficial for several reasons. For one, it allows you to enjoy fresh rhubarb later in the year, when other fruits and vegetables may be scarce. It also gives you the opportunity to use up any remaining stalks before the plant goes dormant for the winter.
Additionally, a fall harvest can help to encourage new growth and promote the health of the plant. By removing some of the older stalks, you’re allowing the plant to focus its energy on producing new growth, which can lead to a more bountiful harvest in the spring.
How Do I Store Rhubarb After Harvesting?
After harvesting your rhubarb, you can store it in the refrigerator to keep it fresh for several days. Simply wrap the stalks in plastic wrap or aluminum foil and place them in the crisper drawer. You can also store rhubarb in the freezer by chopping it into smaller pieces and placing it in an airtight container or freezer bag.
Frozen rhubarb is perfect for using in pies, jams, and other recipes. Simply thaw the frozen rhubarb and use it as you would fresh rhubarb. You can also can or pickle rhubarb to enjoy it throughout the year.
Can I Grow Rhubarb in Containers?
Yes, you can grow rhubarb in containers, but it requires careful consideration and planning. Rhubarb plants need a lot of space to grow, so you’ll need a large container with good drainage. You’ll also need to provide the plant with plenty of sunlight and water.
In addition, rhubarb plants need a period of cold temperatures to induce dormancy, so you may need to move the container to a cooler location during the winter months. With proper care and attention, you can successfully grow rhubarb in a container and enjoy a bountiful harvest.
How Do I Prepare Rhubarb for Eating?
To prepare rhubarb for eating, you’ll need to remove the leaves and trim the ends of the stalks. You can then chop or slice the rhubarb into smaller pieces, depending on your desired use. If you’re using rhubarb in a recipe, you may also need to add sugar or other sweeteners to balance out the tart flavor.
Rhubarb can be used in a variety of dishes, from pies and tarts to jams and sauces. You can also enjoy it raw, either on its own or paired with other fruits and cheeses. Be sure to only eat the stalks, as the leaves contain high levels of oxalic acid and are toxic.
Are There Any Pests or Diseases I Should Be Aware of When Growing Rhubarb?
Yes, there are several pests and diseases that can affect rhubarb plants. Some common pests include aphids, slugs, and snails, which can be controlled with insecticides or other organic methods. Rhubarb is also susceptible to diseases such as crown rot and leaf spot, which can be caused by fungal or bacterial infections.
To prevent pests and diseases, be sure to provide your rhubarb plant with good air circulation and plenty of sunlight. You should also water the plant carefully, avoiding overhead watering which can lead to fungal diseases. Regularly inspect your plant for signs of pests or diseases, and take action promptly if you notice any problems.
