Pumpkins are one of the most iconic symbols of autumn, and their vibrant orange color is a significant part of their appeal. Whether they’re used for carving jack-o’-lanterns, baking pies, or simply as a decorative element, pumpkins are a staple of the season. But have you ever wondered what happens to pumpkins after they’re picked? Specifically, will they continue to turn orange, or does the ripening process come to a halt once they’re removed from the vine? In this article, we’ll delve into the world of pumpkins and explore the fascinating process of how they change color, as well as what happens to them after they’re picked.
Understanding Pumpkin Color Change
Pumpkins, like other types of squash, undergo a process called “ripening” as they mature. This process is triggered by a combination of factors, including the production of ethylene gas, a natural plant hormone that promotes fruit ripening. As pumpkins ripen, the chlorophyll, which gives them their green color, begins to break down, allowing the hidden pigments of carotenoids and lycopene to become visible. Carotenoids are responsible for the yellow, orange, and red colors of many fruits and vegetables, while lycopene is the pigment that gives tomatoes their characteristic red color. In the case of pumpkins, the combination of these pigments results in the distinctive orange hue that we associate with them.
The Role of Ethylene Gas in Ripening
Ethylene gas plays a crucial role in the ripening process of pumpkins. As the fruit matures, it begins to produce more ethylene gas, which in turn stimulates the production of enzymes that break down the cell walls and soften the tissue. This process, known as ” Senescence,” is a natural part of the aging process in plants. As the cell walls break down, the pumpkin becomes more susceptible to disease and decay, which is why it’s essential to handle them carefully and store them properly after picking.
Factors That Influence Color Change
Several factors can influence the color change of pumpkins, including:
The variety of pumpkin: Different types of pumpkins have varying levels of carotenoids and lycopene, which can affect their final color.
Temperature: Pumpkins ripen more quickly in warmer temperatures, while cooler temperatures can slow down the process.
Light: Pumpkins that are exposed to direct sunlight will typically ripen more quickly than those that are shaded.
Water: Consistent moisture levels can promote healthy growth and ripening, while drought stress can slow down the process.
What Happens to Pumpkins After Picking?
Once pumpkins are picked, the ripening process doesn’t come to a complete halt. While they will no longer produce ethylene gas at the same rate as they did on the vine, they can still continue to ripen and change color to some extent. The key factor that determines how much a pumpkin will continue to ripen after picking is the stage of maturity at which it was harvested. Pumpkins that are picked when they’re fully mature will typically not change color much, if at all, while those that are picked when they’re slightly immature may continue to ripen and turn orange.
Handling and Storage of Pumpkins
To keep pumpkins fresh and prevent them from decaying, it’s essential to handle them carefully and store them properly. This includes:
Curing: Allowing the pumpkin to dry and harden in a warm, dry place for 7-10 days can help to extend its shelf life.
Storage: Pumpkins should be stored in a cool, dry place, away from direct sunlight and moisture.
Handling: Pumpkins should be handled carefully to avoid bruising or scratching, which can create entry points for disease.
Extending the Shelf Life of Pumpkins
By following proper handling and storage procedures, it’s possible to extend the shelf life of pumpkins for several months. In fact, some types of pumpkins, such as the ‘Jack Be Little’ variety, can be stored for up to 6 months if they’re cured and stored properly. However, it’s worth noting that the quality and flavor of pumpkins will degrade over time, so they’re best used within a few weeks of picking for optimal flavor and texture.
Conclusion
In conclusion, pumpkins can continue to turn orange after picking, but the extent to which they do so depends on the stage of maturity at which they were harvested. By understanding the process of ripening and the factors that influence color change, growers and consumers can better appreciate the complex and fascinating world of pumpkins. Whether you’re a seasoned gardener or simply a fan of these iconic autumnal fruits, there’s no denying the magic and wonder of watching a pumpkin transform from a green, immature gourd into a vibrant, orange masterpiece.
- To promote healthy growth and ripening, pumpkins should be provided with consistent moisture levels and full sun.

By following these tips and continuing to learn about the fascinating world of pumpkins, you can enjoy these incredible fruits for months to come. Whether you’re using them for cooking, decorating, or simply as a centerpiece for your autumnal celebrations, pumpkins are sure to bring a touch of warmth and magic to your life.
Will Pumpkins Continue to Turn Orange After Picking?
Pumpkins will generally continue to ripen and turn orange after they have been picked, but this process is limited. The ripening process is influenced by the production of ethylene gas, which is a natural process in many fruits and vegetables, including pumpkins. Once a pumpkin is picked, it will continue to produce ethylene gas, which helps to break down the chlorophyll and develop the orange color. However, the rate of ripening will depend on factors such as the variety of pumpkin, the stage of maturity when it was picked, and the storage conditions.
The key to allowing a picked pumpkin to continue turning orange is to store it in a warm, dry place with good air circulation. A temperature range of 50-60°F (10-15°C) is ideal for ripening pumpkins. It’s also important to avoid exposing the pumpkin to direct sunlight, as this can cause it to become over-ripe and develop soft spots. If the pumpkin is stored properly, it can continue to ripen and develop its orange color over the course of several days or weeks. However, if the pumpkin is not yet fully mature when it is picked, it may not turn orange at all, or it may only develop a partial orange color.
How Do I Know If My Pumpkin Is Ripe and Ready to Pick?
To determine if your pumpkin is ripe and ready to pick, you should check its color, texture, and stem. A ripe pumpkin will typically have a uniform orange color, although some varieties may retain some green or yellow stripes. The rind should be hard and dry, and the stem should be dry and brittle. You can also check the pumpkin’s maturity by thumping it gently; a ripe pumpkin will have a deep, hollow sound. If the pumpkin is not yet fully ripe, it can be left on the vine for a few more days to allow it to mature further.
It’s also important to handle the pumpkin carefully when checking for ripeness, as the skin can be easily damaged. Avoid squeezing or pinching the pumpkin, as this can cause bruising or soft spots to develop. Instead, gently lift the pumpkin and check its underside for any signs of yellowing or softening, which can indicate that it is over-ripe. If you are unsure whether your pumpkin is ripe and ready to pick, it’s always best to err on the side of caution and leave it on the vine for a few more days to allow it to mature further.
Can I Speed Up the Ripening Process of a Picked Pumpkin?
While it’s not possible to significantly speed up the ripening process of a picked pumpkin, you can take steps to encourage it to continue ripening. One way to do this is to store the pumpkin in a warm, dry place with good air circulation, as mentioned earlier. You can also try placing the pumpkin in a paper bag with an apple or banana, as these fruits produce ethylene gas, which can help to stimulate the ripening process. However, it’s worth noting that this method is not always effective, and the pumpkin may not ripen significantly faster as a result.
It’s also important to avoid trying to speed up the ripening process by exposing the pumpkin to direct sunlight or high temperatures. This can cause the pumpkin to become over-ripe and develop soft spots, which can reduce its quality and shelf life. Instead, focus on providing the pumpkin with a stable, warm environment that allows it to ripen naturally. With proper storage and care, a picked pumpkin can continue to ripen and develop its orange color over the course of several days or weeks, allowing you to enjoy it at its best.
How Long Will a Picked Pumpkin Last?
The shelf life of a picked pumpkin will depend on a number of factors, including the variety, storage conditions, and handling. In general, a well-cared-for pumpkin can last for several weeks to several months after it is picked. If stored in a cool, dry place with good air circulation, a pumpkin can last for 2-3 months or more. However, if the pumpkin is exposed to heat, moisture, or direct sunlight, its shelf life will be significantly shorter.
To maximize the shelf life of a picked pumpkin, it’s essential to store it properly. This means keeping it away from direct sunlight, heat sources, and moisture. You should also avoid stacking or piling pumpkins on top of each other, as this can cause them to become bruised or damaged. Instead, store the pumpkin in a single layer, with plenty of space around it for air to circulate. With proper storage and care, a picked pumpkin can remain fresh and intact for a long time, allowing you to enjoy it throughout the fall season.
Can I Use a Green Pumpkin If It Doesn’t Turn Orange?
While a green pumpkin may not be as visually appealing as an orange one, it can still be used for cooking and other purposes. In fact, many varieties of pumpkin are harvested when they are green and unripe, and then allowed to ripen and cure before being used. Green pumpkins can be used in a variety of dishes, including soups, stews, and baked goods. However, keep in mind that a green pumpkin may not be as sweet or flavorful as a ripe, orange one.
If you plan to use a green pumpkin, you should first allow it to cure and ripen for a few days or weeks. This will help to break down the cell walls and develop the flavor and texture of the pumpkin. You can also try roasting or baking the pumpkin to bring out its natural sweetness and flavor. However, if the pumpkin is not yet fully mature, it may not be suitable for eating, and it’s best to wait until it has fully ripened before using it. With a little patience and care, even a green pumpkin can become a delicious and versatile ingredient.
Do All Varieties of Pumpkin Turn Orange?
Not all varieties of pumpkin turn orange, although many do. Some varieties, such as the ‘Lumina’ or ‘Ghost Rider’, have a white or pale yellow skin that remains unchanged even when the pumpkin is fully ripe. Other varieties, such as the ‘Jarrahdale’ or ‘Australian Blue’, have a bluish-gray skin that may develop a yellow or orange tint, but will not turn fully orange. The color of a pumpkin is determined by its genetic makeup, and some varieties are bred specifically for their unique skin color and pattern.
If you’re looking for a pumpkin that will turn orange, you should choose a variety that is known for its orange color, such as the ‘Jack Be Little’ or ‘Sugar Pie’. These varieties will typically develop a deep orange color as they ripen, and will have a sweet, flavorful flesh. However, if you’re looking for a pumpkin with a unique skin color or pattern, you may want to consider a variety that doesn’t turn orange. With so many different varieties of pumpkin available, you’re sure to find one that meets your needs and preferences.
