Fall is in the air, and that means it’s time to start thinking about pumpkins! Whether you’re a farmer getting ready to harvest your crop, a gardener planning next year’s garden, or just curious, this guide has everything you need to know about pumpkins. From planting and harvesting to storing and watering, we’ll cover it all. So grab a warm drink and settle in for a comprehensive guide to all things pumpkin.
What are pumpkins?
Pumpkins are a type of winter squash that belongs to the cucurbit family, which also includes cucumbers, melons, and gourds. Native to North America, pumpkins are now grown all over the world. Pumpkins come in many different sizes, shapes, and colors, but the most common variety is the orange pumpkin with smooth, ribbed skin.
Pumpkins are usually harvested in October, making them the perfect fall decoration. But these gourds are more than just decoration;. Pumpkin puree can be used in pies, breads, muffins, and even soups. And don’t forget about those seeds. Roasted pumpkin seeds make a great healthy snack.
Pumpkin height and spread
A pumpkin plant can reach a height of 24 inches; the spread, however, can be between 50-100 square feet, depending on the variety. While you can trellis several different varieties of pumpkins, a hanging pumpkin will need a lot of support, or it will break off the vine. Smaller varieties, such as Jack-Be-Little, are best for this, while larger varieties, such as the Jarrahdale or the Cinderella, are best left to grow on the ground due to their weight.
Whether you’re planting pumpkins in your garden or buying them at the farmer’s market, there are many different varieties to choose from. Each variety has its own unique characteristics and benefits, so it’s important to do some research before making a purchase.
Pumpkin soil needs
If you’re thinking about planting pumpkins, here are a few things you should know. Pumpkins need full sun and well-drained soil with plenty of organic matter. They’re also heavy feeders, so they will need to be fertilized regularly (every two weeks at maximum, monthly at minimum). Soil temperatures are best when they are between 65 to 85 degrees Fahrenheit in order to achieve optimal germination. A pumpkin seed can take anywhere between 7-10 days to germinate.
Pumpkin planting and times
There is a common misconception that pumpkins are planted in the fall. Instead, pumpkins do best when they are directly sown into the soil after the dangers of the last frost have passed in the spring. They do not tolerate frost and typically reach maturity in 3-4 months.
Pumpkins do not do well grown in containers as they need to “sprawl”. For best results, plant directly in the ground.
Pumpkin sun requirements
As previously mentioned, pumpkins require full sun. While you can plant them in partial shade, they will not grow as large or produce as much fruit.
Pumpkin watering needs
While one of the more low-maintenance vegetables, pumpkins need at least 1 inch of water every week. To achieve maximum production in times of drought, they may need as much as 2 inches of water due to their high moisture content.
Pumpkin Issues
Pumpkin plants can be resilient but do have several known pests and diseases to look out for.
Pests:
-Aphids
Aphids are small green, brown, or pink insects with pear-shaped bodies that suck the juices out of pumpkin leaves. If you notice your pumpkin has foliage that curls, puckers, or have turned yellow, there is a good chance that you have aphids. You can find them in clusters on the underside of leaves or you may find them if you notice you have an ant problem. Aphids produce a honeydew that attracts ants and may be an indicator that you have a bigger problem.
Solution – Aphids can be controlled using a hose to wash them off the plant, or using an insecticidal soap. You can also use diatomaceous earth to help prevent infestations.
-Cucumber Beetles
Cucumber beetles are small striped insects that feed on pumpkin leaves and stems, causing the plant to wither and die. They can also transmit illnesses to the plant, such as bacterial wilt or mosaic virus.
Solution – The best way to prevent cucumber beetles is to use a floating row cover over your plants. You can also use an insecticidal soap or neem oil to help control populations.
-Squash Vine borers
Squash vine borers are the larvae of a nighttime moth that feeds on the stem tissue of pumpkins, resulting in wilting vines, yellowing leaves, and stunted growth. These pests are extremely difficult to control and feed on the vines of pumpkin plants, causing them to sicken and, ultimately, die. The tell-tale sign of a vine borer is a moist, sawdust-like substance called “frass” that can be found at the base of your plant.
Solution – You can inject Bacillus thuringiensis (BT) into the stem with a needle. BT works by releasing a toxin that kills the borers. You can also plant varieties that are resistant to vine borers, or cover your plants with floating row covers. Additionally, you can gently slit the stem and try to remove the vine borer yourself. After removing, cover the split with soil to prevent any other borers from entering. Finally, use traps in your garden can help attract and kill adult moths before they lay eggs on your plants.
-Squash bugs
Squash bugs are large, often grey, shield-shaped insects that suck the sap out of pumpkin leaves, resulting in yellow/black spots or holes. If you have a plant that looks wilted only to blacken later and die, there is a good chance you are battling squash bugs.
Solution – These bugs are our biggest nemesis in the garden, and the best way to prevent these pests is by picking them off manually or spraying your plants with an insecticidal soap spray regularly. You can also utilize crop rotation or succession sow to increase your chance of a productive harvest.
Diseases:
-Powdery Mildew
Powdery mildew is a common fungal infection that causes white patches to form on pumpkin leaves and stems, eventually killing the plant if left untreated. It thrives in warm, moist climates and is easily identifiable by its characteristic powdery texture.
Solution – To treat powdery mildew, you can apply neem oil or sulfur when conditions are favorable for it (warmer temperatures and low humidity). Additionally, you can remove infected leaves and debris from your garden, as well as rotate crops regularly to prevent the build-up of fungi in the soil. Finally, using strong air circulation in your garden and planting resistant varieties can help reduce the risk of mildew.
-Rot
Pumpkin rot is a common disease that results in tell-tale soft spots on pumpkin fruits. It is caused by fungi or bacteria that are present in poorly drained soils or high humidity levels. Rot symptoms include sunken areas on fruit with watery flesh inside.
Solution – To prevent rot from occurring, make sure you are providing your plants with ample drainage and avoid overwatering them during wet conditions. You can treat infected fruits by removing the affected portions. In addition, using crop rotation, succession planting, and growing resistant varieties can help reduce your risk of rot. You may also utilize bacterial sprays if there is an outbreak in your garden.
-Bacterial Wilt
Bacterial wilt is another common disease that affects pumpkin plants, resulting in stunted growth and yellowing leaves. It can be caused by bacteria that is spread through insect feeding or contaminated water.
Solution – To prevent bacterial wilt from occurring, you can use crop rotation to avoid growing the same plant in the same location for several seasons. You should also monitor your garden closely for any signs of infection and remove infected plants immediately to stop the spread. Using resistant varieties can help reduce your risk of infection, as well as treating your plants with insecticides or neem oil if you notice an outbreak of pests. Finally, keeping your garden free from debris can also help prevent this disease from taking hold in your garden.
-Anthracnose
Anthracnose is a fungal infection that causes dark spots to develop on pumpkin leaves and fruits, eventually leading to the death of the plant if left untreated. It thrives in warm and wet conditions, such as those found during the summer months.
Solution – There are several approaches you can take to treat anthracnose in your garden. One option is to remove any affected leaves or fruits immediately. This can reduce the spread of spores and prevent further damage. You can also use fungicides or neem oil to treat infected plants, as well as improving air circulation. Providing adequate drainage for your plants is imperative for a healthy crop. Additionally, using resistant varieties and crop rotation can help reduce your risk of anthracnose developing.
Overall, there are many potential pests and diseases that can affect pumpkin crops. To prevent infestations and infections from harming your plants, it is important to regularly inspect your plants for signs of damage. Take action immediately if you spot any problems. Some common treatment methods include using neem oil, manually removing insects or diseased leaves from the plant, or rotating crops regularly to keep fungi levels low.
Pumpkin harvesting and storage
Pumpkins are ready to harvest when they are a uniform color (typically orange) and sound hollow when you knock on them. You can also look at the stem; a brown stem means it’s ready to pick, while one with a green stem may need a little more time. Cut carefully with pruning sheers, making sure to leave the stem intact on the pumpkin.
After harvesting, it is important to store your pumpkins in a cool, dry place with good air circulation. If you intend to use your pumpkin right away, you can also cook or carve it immediately for maximum flavor. However, if you are planning on storing or selling your pumpkins for longer periods of time, be sure to handle them carefully. Take care not to damage their outer skin by avoiding stacking them to prevent crushing or cracking.
