That said, it's not uncommon for amateur pumpkin gardeners to face issues as fall approaches—and one common issue is the pumpkin plant growing flowers but not fruit. For anyone trying to grow a pumpkin, there's nothing more frustrating than the plant refusing to actually produce a pumpkin!
But why do some pumpkin plants produce flowers but not fruit? To understand, Parade consulted with a bonafide pumpkin expert: Steve Jacobsen, farmer and owner of the Solvang Farmer Pumpkin Patch in Solvang, Calif, who shared six reasons why you might be experiencing this issue.

Why Your Pumpkin Plant Has Flowers but No Pumpkins
1. Insufficient pollination

Each pumpkin plant has both male and female flowers, he explains. Typically, male flowers bloom first, and female flowers bloom two weeks later (or even later, if weather is very hot), per Gardening Know How. If the female flowers on a pumpkin plant are not pollinated, then the plant will not grow any fruit.
"Insects, primarily bees, are the mechanism for the flowers to be pollinated," adds Jacobsen. "That is why it is important to foster the local bee population."
In general, the soil's temperature should be at least 60 degrees Fahrenheit, though some varieties of pumpkin require the soil to be at least 75 degrees Fahrenheit, according to Jacobsen.
Gardening Know How also notes that a surplus of nitrogen in the soil can cause a pumpkin plant to mostly grow male flowers, but not female flowers or pumpkins. And, as we know, a lack of female flowers on a pumpkin plant means no pumpkins. So, it's important to make sure your nitrogen levels aren't too high.
3. Not enough sunlight or warm weather
"Pumpkins need heat to grow," explains Jacobsen. "Generally, plants will grow larger with temperatures above 80 degrees."
And per Gardening Know How, when temperatures fall below 60 degrees Fahrenheit, bees may stay out of shaded areas—so if your pumpkin plants are in the shade for too many hours each day, they may not get sufficiently pollinated, and may not produce fruit.
4. Low quality seeds

To keep your seed haul safe until next year, Thistle Downs Farm recommends rinsing and then drying out your seeds on paper towels for at least three weeks. Then, store them in a paper envelope "that prevents it from being exposed to light, heat and moisture," says Jacobsen.
If you are having trouble growing pumpkins and you notice any of these critters nearby, you may want to look into humane ways to keep these animals away from your garden.
6. Not enough space
"Good pumpkin yield, particularly with pumpkins over 20 pounds, require several feet in between each plant," he says. "For very large pumpkins, the general rule is one fruit per plant. Too many fruits on one plant may reduce the size and quality of the pumpkins the plant produces."

"Some varieties will produce fruit in approximately 50 days," says Jacobsen. "Some other varieties, particularly the large ones, require over 120 days to produce the pumpkin desired." The seed package should state how many days you can expect your plant to take to reach maturation.
What Time Of Year Is Best to Plant Your Pumpkins?
However, if you want your pumpkins to be ready in time for Halloween, you should ideally plant them in late June; if you don't need them until Thanksgiving, you can plant them in mid-July, per A Modern Homestead. And if it's too hot outside then, you can start by planting your seeds inside, and then later transfer them to your pumpkin patch.
