Would pumpkin flowers turn into PUMPKINS? Or want to eat them instead? I am there to answer you. To begin with, yes, the pumpkin flower is edible!

I understand that you might compare pumpkins with squash. Sometimes any round orange squash is called a PUMPKIN too!

I tell you that pumpkins belong to the same genetic family called Cucurbita as squash. You can depend on my gardening knowledge about pumpkins plant over all these years.

What are the Types of Pumpkin Flowers and Their Difference?

What are the Types of Pumpkin Flowers and Their Difference

The flowers from pumpkin seeds are FUNNEL-SHAPED that are bright orange or yellow. They may be about 4-5 inches in diameter. Pumpkin blossoms are either male flowers or female ones. 

Both look different and contribute differently to pumpkin fruit growth. The pumpkin species and environment determine flowering time. The pumpkin plant makes both male and female flower parts. They are called staminate and pistillate, respectively.

There’s a clear difference between the male and female pumpkin flowers. Male pumpkin flowers come right off the vine. In contrast, female pumpkin flowers have a small fruit growing at the base near the stem. 

Don’t worry if the pumpkin vine flowers come early in the season but don’t produce fruit. Male flowers bloom first, so bees take them along their POLLEN PATH. 

Waiting for the female flowers may work. Female pumpkin flowers bloom TWO WEEKS AFTER MALE FLOWERS are on them.

Problems Related to Pumpkin Flowers During the Blooming Stage

Problems Related to Pumpkin Flowers

Let’s learn the problems related to pumpkin plant flowers during the blooming stage:

Flowerless

Pumpkin gardeners anxiously expect blossoms and fruit. Since last year, no pumpkin! I suggest using phosphorus fertilizer. This results in plants blooming and fruiting. 

Avoid using Nitrogen fertilizers during the bloom stage. They might also DELAY BLOSSOMING.

Only Male Flower

Male blossoms usually arrive first in large numbers. After a week without ladies, you start to worry. Female pumpkin flowers appear 10-14 days after the first male (**occasionally longer!**). Only a few ladies will appear. Males usually OUTNUMBER females.

Only Female Flowers

Female pumpkin flowers rarely appear first. This might sometimes happen on pollen-laden male blooms but is short-lived. The male flowers eventually arrive. Season-long, more female and male blossoms will come for SUCCESSFUL PUMPKIN POLLINATION. 

Female flowers sometimes arrive first. This may happen due to soil fertility levels, as some people say. Or others say early-season cold snaps may predispose the plant to this situation. 

Check the fertility of the soil. Keep suitable to high phosphorus levels. Avoid too much nitrogen; its level should be MODERATE.

Do two things for less male blossom conditions. First, place ripe male flowers in a glass of water and refrigerate. Do hand pollination with them as needed. They last a week when refrigerated. Second, ASK A PUMPKIN-GROWING FRIEND to get some male blooms for hand pollination.

Unopened Female Flowers

Pumpkins are usually missed by growers when finding any OPEN FEMALE FLOWER. The reason is female pumpkin flowers open one morning and close before noon. Cloudy and rainy weather can prevent their opening.

The Reason Your Pumpkin Isn’t Blooming

Reason Your Pumpkin Isn't Blooming

Pumpkin plant not blooming – why? IMPATIENCE is a common reason for this. Pumpkin plants bloom after establishing numerous critical stems. 

When do plants blooms? The time depends on the variety, climate, and when you installed them outdoors. Expect plants to BLOOM IN SIX TO EIGHT WEEKS after planting.

Now let’s discuss FLORAL SEX. Pumpkins, like squash, grow both male and female flowers for pollination and fruit. Male flowers bloom earliest. Female pumpkin flowers appear after 10 to 14 days

You can have a look at the reasons for pumpkins not blooming as follows:

  • You might not be looking often enough to see male and female flowers if you didn’t see any during this time. Each plant flower lasts one day and opens in the morning

When there are no female flowers to pollinate, early male blooms die off immediately. Early blossoms require a keen eye. Some plants’ blooms might miss in the stems. 

  • You may also be expecting blooms too soon. Before the first yellow flower appears, healthy pumpkin vines should be a meter long. The time pumpkin plants flower depends on the soil, sunlight, variety, & other factors. 

Each affects plant blooming. Controlling the ground’s fertility and adding flowering nutrients can boost plants blooming.

  • Pumpkins HATE OVERHEAD WATERING. Many fungal diseases can harm leaves and buds as they form due to this. Heavily contaminated buds may abort, leaving your plant bloomless. Pumpkin plants don’t blossom for one more reason that is soil fertility
  • Lack of potassium, a plant’s macronutrient, can IMPAIR BLOOMING. It is available in the form of potash or other potassium compounds in floral and fruit meals. Phosphorus is usually accountable for flower and fruit production. 

After six to eight weeks of planting pumpkin vines, stop nitrogen applications. The pumpkin vines must have nutrition to grow rampant stems in soils with organic matter.

When do Pumpkins Bloom? How Long Does It Last?

When do Pumpkins Bloom

Pumpkins flower somewhere between the end of spring and the beginning of summer. This time of blossoming can extend for a few weeks. Flowers are often open during the day and closed at night. 

On the pumpkin vine, male pumpkin flowers appear before their female counterpart. According to the University of Minnesota Extension, “pumpkin blossoms last 4 hours. A male flower only lasts a few hours”

A NEW MALE PUMPKIN FLOWER opens every morning to lure in the bumblebees or other pollinators. The pumpkin fruit will take the place of the flowers once the blooming completes.

How to Tell If Pumpkin Got Pollinated?

How to Tell If Pumpkin Got Pollinated

Bumblebees, honey bees, and squash bees are the common pollinators of pumpkin blooms. Morning is the prime time for pollination when flowers and bees are most active. TRANSFER POLLEN FROM A BLOSSOM to a developing fruit requires many visits from bees

Each flower can be seen open only one day. If a female pumpkin flower isn’t pollinated on that day, it will turn yellow and EVENTUALLY DIE. To find out if bees are busy in a field, check it out early in the day. 

Do this before the extreme temperatures when blooms close. Even if there is only sporadic bee activity and no existing hives, it is good to bring hives for bees.

Pollen grains must sprout. They should grow after pollination (pollen transfer to the female pumpkin flower). It will lead to fertilizing each ovule, eventually developing into a seed. The pumpkin fruit won’t survive without this. If the pumpkin seeds don’t germinate, the pumpkin will not grow.
