Where Are Pumpkins Grown?

Pumpkins grow in areas with at least eight hours of direct sunlight daily. So pick a sunny spot in your garden. They can grow from Zone 2 to 13. Make mounds of pumpkin seeds and scatter them about four to six feet apart in holes about an inch and a half deep with four to five seeds per hole.

Do you know where pumpkins come from? Many people assume that pumpkins grow on trees, but that’s not true. Pumpkins are grown on vines stretching for up to 20 feet! These vines can produce multiple pumpkins of varying sizes, from small ones that fit in the palm of your hand to massive ones that weigh over a thousand pounds. The pumpkin is a large trailing plant with yellow flowers that resemble bells. It can be damaged by frost. Most types will need a lot of space. Plant them at the edge of your garden to grow without crowding other plants. Butternut trees grow small to medium-sized fruits that look like pears and have orange flesh. Buttercup pumpkins are small to medium-sized and round. Their skin is dark green. Some large pumpkins are round and flat, making them easy to store and eat. Others grow giant round pumpkins that look like “Cinderella’s coach” and are not as good to eat.

When the vines die off and the pumpkin stalks are dry, it’s time to harvest. Leave a small piece of the stalk on the fruit to keep it from going bad when it gets wet. The fruit can be kept for months in a cool, dry place with air circulation. They are kept in some parts of New Zealand on the roofs of sheds.

Pumpkins sometimes need to be pollinated by hand. If the fruits don’t sit well or die after they grow, pick a male flower (the one with the straight stem) and brush pollen into the female flowers.

Pumpkins grow faster when it is hot than when it is cold. If you live where it often frosts, find out when the first frost usually happens. This is the date by which frost will happen half of the time. You can determine when you planted your pumpkin by subtracting the time it took to grow. Here, you can find the date of the first frost. Just type in the zip code for your area to see what comes up.

Growing Tips in Different Areas

Inland Areas

Most gardeners agree that the middle of April is the best time to plant pumpkins. It is the best time to start planting. If you live in the north, wait until late May to plant. For places in the south, plant at the beginning of July. Again, if you want the plant to be fully grown by a certain date, just take away the number of days it takes to grow from the harvest date.

Colder Coastal Areas

Pumpkins won’t grow well in soil that is too cold. So if you plant them where frost can get to them, the pumpkin seeds will just die. The pumpkins should be grown in a container indoors until the risk of frost has passed. When the soil temperature is between 60°-105°F (16°-41°C) outside, it’s time to plant.

Hardiness Zone
