When it comes to harvesting rhubarb, one of the most critical factors to consider is the color of the stalks. The color can signify the readiness, taste, and nutritional value of the rhubarb. In this article, we will delve into the world of rhubarb, exploring the ideal color for picking, the reasons behind the color change, and how to care for your rhubarb plant to achieve the perfect hue.
Introduction to Rhubarb
Rhubarb is a perennial vegetable that is often used in pies, tarts, and jams. It is known for its tart flavor and is usually paired with sweet ingredients like sugar and strawberries. The plant has large, leafy greens and long, stalky stems that are the edible part of the plant. Rhubarb is a cool-season crop, which means it thrives in cooler temperatures and can tolerate light frosts.
Reasons for Color Change
The color of rhubarb changes as it matures. The stalks start as a deep red or green color and gradually turn to a lighter shade of green or even a pale yellow. The color change is due to the breakdown of anthocyanins, which are the pigments responsible for the red, purple, and blue colors of fruits and vegetables. As the rhubarb matures, the anthocyanins break down, revealing the yellow and green pigments underneath. The color change is a natural process and does not affect the taste or nutritional value of the rhubarb.
What Color Should Rhubarb Be When You Pick It?
The ideal color of rhubarb when picking it is a topic of debate among gardeners and chefs. Some prefer the deep red color, while others like the lighter green or pale yellow hue. The color you choose depends on your personal preference and the intended use of the rhubarb. If you prefer a sweeter taste, pick the rhubarb when it is a lighter green or pale yellow color. If you prefer a tangier taste, pick the rhubarb when it is a deeper red color.
Caring for Your Rhubarb Plant
To achieve the perfect color and flavor, you need to care for your rhubarb plant properly. Here are some tips to help you grow healthy and delicious rhubarb:
The rhubarb plant requires full sun to partial shade and well-drained soil. It prefers a slightly acidic to neutral soil pH, ranging from 5.5 to 6.5. The plant needs consistent moisture, especially during the first year after planting. Mulch around the base of the plant to retain moisture and suppress weeds.
Fertilization and Pruning
Fertilize your rhubarb plant in early spring with a balanced fertilizer. Avoid over-fertilizing, as this can lead to weak and leggy stalks. Prune the plant in late winter or early spring, removing any dead or damaged stalks. This will help promote healthy growth and encourage the plant to produce new stalks.
Pest and Disease Management
Rhubarb plants are susceptible to pests and diseases, such as aphids, slugs, and powdery mildew. Keep an eye out for these pests and diseases, and take action promptly if you notice any issues. Use organic or chemical controls as needed, and practice good garden hygiene to prevent the spread of disease.
Harvesting Rhubarb
Harvesting rhubarb is a straightforward process. Simply grasp the stalk at the base and pull it away from the plant. Avoid cutting the stalks, as this can damage the plant and reduce future yields. Harvest the stalks when they are between 10 and 15 inches long, and be sure to leave at least two inches of the stalk attached to the plant.
Timing of Harvest
The timing of harvest depends on the variety of rhubarb and the climate. In general, rhubarb is ready to harvest in late spring to early summer, about 6 to 8 weeks after the plant emerges from dormancy. Harvest the rhubarb when the stalks are tender and have reached the desired color.
Post-Harvest Care
After harvesting, remove any leaves from the stalks, as they contain high levels of oxalic acid and can be toxic. Store the stalks in the refrigerator to keep them fresh. Rhubarb can be frozen or canned for later use, and it can be used in a variety of dishes, from pies and tarts to jams and sauces.
Storing Rhubarb
To store rhubarb, wrap the stalks in plastic wrap or aluminum foil and place them in the refrigerator. The rhubarb will keep for several weeks when stored properly. You can also freeze the rhubarb by chopping it into small pieces and placing it in an airtight container or freezer bag.
Conclusion
In conclusion, the color of rhubarb when picking it is a matter of personal preference. Whether you prefer the deep red color or the lighter green or pale yellow hue, the most important thing is to harvest the rhubarb when it is tender and has reached the desired flavor and texture. By caring for your rhubarb plant properly and harvesting it at the right time, you can enjoy delicious and nutritious rhubarb all season long. Remember to store the rhubarb properly to keep it fresh, and experiment with different recipes to find your favorite way to use this versatile vegetable.

What color should rhubarb be when it is ready to be picked?
Rhubarb is a unique vegetable that is often used in pies, tarts, and other sweet dishes, despite being a tart and savory ingredient. When it comes to determining the perfect time to pick rhubarb, color plays a crucial role. The ideal color for rhubarb is a deep red or pink hue, which indicates that it is ripe and ready to be harvested. However, it’s essential to note that some rhubarb varieties may have a more greenish tint, but they should still have a slight reddish or pinkish coloration.
As the rhubarb plant matures, the stalks will begin to turn from a pale green to a deeper red or pink color. This color change is a sign that the stalks are becoming sweeter and less tart, making them perfect for cooking and eating. It’s also important to check the texture of the rhubarb, as ripe stalks should be slightly tender but still crisp. Avoid picking rhubarb that is too green or too old, as it may be too bitter or fibrous. By choosing rhubarb with the right color and texture, you can ensure that your dishes turn out delicious and flavorful.
How does the color of rhubarb affect its taste and texture?
The color of rhubarb is not just a visual indicator of its ripeness; it also affects its taste and texture. Rhubarb that is more red or pink in color tends to be sweeter and less tart than greener stalks. This is because the red pigment, anthocyanin, is also responsible for the fruit’s sweetness and flavor. On the other hand, greener rhubarb may be more tart and bitter, which can be overwhelming in some recipes. In terms of texture, red or pink rhubarb is generally more tender and less fibrous than green rhubarb.
As rhubarb ripens and turns from green to red, the cell walls begin to break down, making the stalks more tender and easier to cook. This process also helps to reduce the amount of oxalic acid, a naturally occurring compound that can give rhubarb its tart flavor. By choosing rhubarb with the right color, you can achieve the perfect balance of sweet and tart flavors in your recipes. Additionally, the texture of the rhubarb will be more appealing, making it a great addition to a variety of dishes, from pies and tarts to salads and savory sauces.
Can you pick rhubarb when it is still green, and will it still be edible?
While it’s technically possible to pick rhubarb when it’s still green, it’s not necessarily the best option. Green rhubarb is typically more tart and bitter than red or pink rhubarb, which can make it less palatable in some recipes. However, if you do pick green rhubarb, it’s essential to use it in dishes where its tartness will be balanced by other ingredients, such as sugar or sweet fruits. Green rhubarb can also be used in savory dishes, where its tart flavor can add depth and complexity.
It’s worth noting that green rhubarb may not be as tender as red or pink rhubarb, which can make it more difficult to cook and prepare. Additionally, green rhubarb may contain higher levels of oxalic acid, which can be a concern for people with certain health conditions. If you do choose to pick green rhubarb, make sure to cook it thoroughly to break down the cell walls and reduce the amount of oxalic acid. You can also try mixing it with other ingredients to balance out its flavor and texture. With a little creativity, green rhubarb can still be a delicious and edible addition to your recipes.
How does the variety of rhubarb affect its color and edibility?
There are several varieties of rhubarb, each with its unique characteristics, including color, taste, and texture. Some popular varieties, such as ‘Canada Red’ and ‘Valentine’, have a deep red or pink color, while others, like ‘Green Petite’ and ‘Rheinlander’, have a more greenish tint. The variety of rhubarb can affect its edibility, as some types may be more suitable for certain recipes or cooking methods. For example, red or pink rhubarb is often preferred for sweet dishes, while green rhubarb may be better suited for savory recipes.
Regardless of the variety, rhubarb is generally edible and can be used in a wide range of dishes. However, some varieties may be more prone to bolting, which can make them less desirable. Bolting occurs when the rhubarb plant produces seeds, which can cause the stalks to become bitter and fibrous. To prevent bolting, it’s essential to remove any flower stalks that appear and to harvest the rhubarb regularly. By choosing the right variety of rhubarb and following proper harvesting and cooking techniques, you can enjoy delicious and flavorful rhubarb dishes all season long.
Can you force rhubarb to change color by exposing it to sunlight or other environmental factors?
While sunlight and other environmental factors can affect the color of rhubarb, it’s not possible to force it to change color significantly. Rhubarb that is naturally green will not turn red or pink simply by exposing it to sunlight, although it may develop a slight reddish tint. The color of rhubarb is determined by the variety and the stage of ripeness, and it’s influenced by a combination of genetic and environmental factors. However, providing rhubarb with the right growing conditions, including adequate sunlight, water, and nutrients, can help to promote healthy growth and development.
It’s worth noting that some gardeners use a technique called “forcing” to encourage rhubarb to grow and ripen more quickly. Forcing involves covering the rhubarb plant with a container or bag to exclude light and promote etiolation, which can cause the stalks to grow more rapidly and develop a more intense color. However, this technique is typically used to encourage earlier growth, rather than to change the color of the rhubarb. By providing rhubarb with the right care and attention, you can help it to grow and thrive, and enjoy a bountiful harvest of delicious and flavorful stalks.
How does the color of rhubarb affect its nutritional value and health benefits?
The color of rhubarb can affect its nutritional value and health benefits, as different pigments are associated with various vitamins, minerals, and antioxidants. Red or pink rhubarb, for example, contains high levels of anthocyanins, which are powerful antioxidants that have been linked to several health benefits, including reducing inflammation and improving cardiovascular health. Green rhubarb, on the other hand, may contain higher levels of chlorophyll and other green pigments, which can provide additional nutritional benefits.
Regardless of the color, rhubarb is a nutrient-rich food that is high in fiber, vitamins, and minerals. It’s a good source of vitamin C, potassium, and manganese, and it contains a range of phytochemicals that have been linked to several health benefits. Rhubarb has been shown to have anti-inflammatory properties, and it may help to support digestive health and reduce the risk of certain diseases. By incorporating rhubarb into your diet, you can enjoy a range of nutritional and health benefits, and the color of the rhubarb can provide an additional boost to its overall nutritional value.
Can you use rhubarb that has been frozen or stored for a long time, and will it still retain its color and flavor?
Rhubarb can be frozen or stored for a long time, but its color and flavor may be affected by the storage method and duration. Frozen rhubarb can retain its color and flavor relatively well, especially if it’s frozen soon after harvesting and stored at a consistent freezer temperature. However, frozen rhubarb may become slightly softer and more prone to browning, which can affect its texture and appearance. Stored rhubarb, on the other hand, may lose some of its color and flavor over time, especially if it’s not stored properly.
To maintain the color and flavor of stored rhubarb, it’s essential to store it in a cool, dry place, away from direct sunlight and moisture. You can also try storing rhubarb in airtight containers or bags to prevent moisture and other contaminants from affecting its quality. When using frozen or stored rhubarb, it’s best to use it in cooked dishes, where the heat can help to break down the cell walls and restore some of the natural flavor and texture. By following proper storage and handling techniques, you can enjoy delicious and flavorful rhubarb dishes all year round, even when the fresh rhubarb season is over.
