Pumpkins are a popular fall crop that is often associated with Halloween and Thanksgiving. They are known for their large size, bright orange color, and sweet flavor.
But have you ever wondered why pumpkins continue to grow even after they turn orange?
The answer lies in the fact that pumpkins are indeterminate plants. This means that they do not have a predetermined size or shape, and they will continue to grow until they are killed by frost or other environmental factors.
In this article, we will take a closer look at the science behind indeterminate growth in pumpkins. We will also discuss the factors that affect pumpkin growth and how to harvest pumpkins at the right time.
Key Facts
Pumpkins continue to grow even after turning orange due to two distinct phases of development. The first phase is rapid growth, which occurs after the flower drops off. During this phase, the fruit is generally unripe, and the main growth happens. The second phase is characterized by slower growth, ripening of the seeds, hardening of the exterior, and changes in the flesh. This phase is focused on maturing rather than volume increase.
During the second phase, you may observe color change early on, while other changes occur later. The green stem of the pumpkin indicates that the plant is still supplying water and nutrients to the fruit. The choice of when to harvest the pumpkin depends on its intended use. For optimal storage capabilities, it is recommended to wait until the stem starts drying up. However, if you plan to use the pumpkin sooner, you can harvest it slightly earlier.
It is worth noting that pumpkins are edible at all stages of growth, so you can consume them even before they turn fully orange.
The pumpkin growth process
The process of growing pumpkins is a fascinating and complex one that takes place over several months. From planting the seeds to harvesting the pumpkins, there are many factors that can affect the growth and development of these plants.
The first step in the pumpkin growing process is planting the seeds. Pumpkin seeds are typically planted in the spring after the danger of frost has passed. The seeds are planted about an inch deep in soil that has been amended with compost or other organic matter.
Once the seeds are planted, they will begin to germinate and sprout. As the plants grow, they will develop a system of roots, stems, and leaves. The leaves play an important role in the growth process by using sunlight to produce energy through photosynthesis.
As the pumpkin plants mature, they will begin to produce flowers. These flowers are critical to the growth process as they are the means by which the plants are pollinated. Without pollination, the plants will not produce fruit.
Once the flowers have been pollinated, the plants will begin to produce fruit, which is the pumpkin itself. The pumpkins start out small and green and gradually grow larger over time. As they grow, they change color and develop a hard outer skin.
Throughout the growing process, pumpkins need regular watering and fertilizing to ensure they get the nutrients they need to grow and develop properly. They also need plenty of sunlight to allow the plants to produce energy through photosynthesis.
In addition to these factors, there are many other variables that can affect the growth and development of pumpkins. These include soil quality, temperature, and pest and disease control. By carefully managing these factors, farmers and gardeners can help ensure that their pumpkins grow and develop to their full potential.
Debunking the myth
Contrary to popular belief, pumpkins do not stop growing when they turn orange. In fact, pumpkins continue to grow and ripen even after they reach their full size and turn orange. This is because the pumpkins are still alive and growing as long as they remain attached to the vine. As the pumpkin ripens, it will continue to draw nutrients and water from the vine, allowing it to continue to grow and ripen.
However, it is important to note that pumpkins will eventually reach a point where they stop growing and begin to deteriorate. This can happen for a number of reasons, including disease or damage to the pumpkin. In addition, pumpkins left on the vine too long can become overripe and lose their flavor and texture.
Pumpkin harvesting tips
If you are growing pumpkins in your garden and want to harvest them at the right time, there are a few things to keep in mind. First, look for signs that the pumpkin is ripe, such as a hard skin and a hollow sound when tapped. Second, be sure to cut the pumpkin from the vine with a sharp knife or pruning shears, taking care not to damage the stem or the pumpkin itself. Finally, store the pumpkin in a cool, dry place to help it last longer.
- Check the color: When a squash is fully ripe, it has a rich, deep orange color. If your squash is still green or has a patchy color, it may not be fully ripe.
- Look at the stem: The stem of a ripe squash should be hard and dry. If it is still green and pliable, the pumpkin may not be ready to harvest.
- Knock the pumpkin: When you tap a ripe squash, it should sound hollow. If it sounds dull or solid, the squash may not be fully ripe.
- Check the skin: The skin of a ripe squash should be hard and resistant to puncture or scratching. If the skin is soft or easily damaged, the squash may not be ready to be harvested.
- Leave some stem: When you cut the squash from the vine, be sure to leave a few inches of stem attached. This will help prevent the pumpkin from rotting and make it easier to handle.
By following these tips, you can ensure that your pumpkins are fully ripe and ready to harvest. Once you have harvested your pumpkins, you can use them for a variety of purposes, such as carving jack-o-lanterns, making pumpkin pie, or roasting pumpkin seeds. So go ahead and enjoy the fruits of your labor, knowing that you picked your pumpkins at the right time for the best flavor and texture.
The bottom line
The myth that pumpkins stop growing when they turn orange is just that – a myth. Pumpkins will continue to grow and ripen as long as they remain attached to the vine, drawing nutrients and water from the plant. However, it is important to harvest pumpkins at the right time to ensure that they are fully ripe and have the best flavor and texture. So go ahead and enjoy your squash, knowing that they will continue to grow and develop even after they turn orange.
FAQs
Do pumpkins stop growing when they turn orange?
Pumpkins do not stop growing when they turn orange. If there is no frost and the vine and leaves are healthy, they will continue to grow through the ripening process. However, once they turn orange, they are usually ready for harvest.
Why did my pumpkin stop growing?
Pumpkin Vine Drought Stress
Because they are 90 percent water, pumpkins require daily watering. When their source of water is diminished, their growth becomes stunted, resulting in smaller-than-expected pumpkins. To prevent this, make sure your pumpkin vines get water every day.
How long do pumpkins last after they turn orange?
Properly stored pumpkins keep for at least three months and may last as long as seven months. Check the pumpkins for soft spots or other signs of rot from time to time. Throw away rotting pumpkins or cut them up and add them to the compost pile.
Why are my pumpkins turning orange early?
For the pumpkins to turn orange, they continue to need warmth and sunshine. As summer wanes, the days become shorter and the nights get colder. In turn, the pumpkins slowly change from green to orange, and the shells begin to harden. Tip: Keep in mind that different types of pumpkin will not be as orange as you expect.
How long will pumpkins grow?
Most types mature in 90 to 100 days, but it can take as long as 120 days for pumpkins to grow to full size. Read the seed package so you’ll know what to expect and plant so that you’ll have plenty of time to harvest before a frost; pumpkins tolerate zero cold!
Why are my baby pumpkins turning yellow and dying?
Pumpkins turn yellow and die when heavily infested with certain sap-sucking and vine-boring pests. Whiteflies cluster underneath plant leaves, sucking sap and excreting sticky honeydew, and fly up into the air when disturbed.
Should you water pumpkins everyday?
Should You Water Pumpkins Every Day? While you can water pumpkins every day, it is better to water pumpkins only a few times a week. Not only is it less of a time commitment, but it also helps your plants.
Will my green pumpkins turn orange after picking?
Green pumpkins will not turn orange after a killing frost, but green pumpkin harvesting is better than allowing them to rot in the field. Green pumpkins may ripen up slightly given some time, warmth, and sunlight.
Will a green pumpkin turn orange after you pick it?
Place the green side to the sun – The sun will help the green part of the pumpkin turn orange. If you have a pumpkin that is only partially green, face the green side towards the sun. If the whole pumpkin is green, rotate the pumpkin evenly for an even change to orange.
