How Do I Grow a Pumpkin?

home garden

Growing a pumpkin can be a fun choice for the beginning gardener or for young children learning about plants. There are many different types of pumpkins, and most are relatively easy to grow. There are several tips and strategies to help the beginning grower to create a large pumpkin to use as a Jack-o-Lantern, or several small pumpkins for use in pies.

The pumpkin requires lots of sun and good soil for best results. Choose a sunny spot in your yard and consider using a little bit of organic compost to fill the hole once you dig. You should also choose whether to grow the plant from seed or from seedlings. Growing the pumpkin from a seedling is easier, while seeds should be started inside before being transferred to the growing site. Usually you should allow the seedling to become several inches in height prior to planting.

Pumpkin seedlings can usually be purchased in gardening stores and sometimes in hardware stores with gardening departments. Planting in the US should begin in early July for a good yield by early fall. There are many pumpkin varieties to consider, and it is best to take the advice of the gardening department on which plants are most successful in your specific area. In most cases, if you are planting pumpkins for pies, the small, dense sugar pumpkin variety is preferred.

When purchasing seedlings, buy at least two. Pumpkins need to be pollinated in order to produce fruit. If you purchase only two seedlings, you will get one plant that yields a pumpkin or pumpkins.

The next step is to mound the soil. You should make a small hill about 2 inches (5.08 cm) in height. This gives the plant more space to expand its roots and discourages the development mildew, which can destroy the growing pumpkin. The seedling should be inserted about 1 inch (2.54 cm) into the mound.

The two pumpkin plants should be separated by at least 1 foot (30.48 cm), but not much farther. The goal is to make sure that honeybees will pollinate the flowers to produce pumpkins. The chance of pollination increases with more planted seedlings. Avoid using pesticides like malathion in your garden, which can kill honeybee populations.

Pumpkins require watering every few days, but you should not over water the plant. Unless the weather is particularly hot and the leaves seemed withered, the plant should receive water no more than every other day. The pumpkin will quickly spread in the hot sun, and flowers will appear within a month to six weeks, depending on the size of the initial seedling.

If you are trying to grow a large pumpkin, you will need to eliminate all but one of the small fruits when they develop. You should choose the best looking of the pumpkins to remain, and neatly trim off its companions. Be sure to inspect the vine of the pumpkin you intend to keep, and choose the one likely to receive the most sun. If the vine looks unhealthy, choose a different pumpkin. Smaller varieties do not have to be trimmed off, as they can produce four to five pumpkins from a single plant, and occasionally produce up to a dozen.

Once you have trimmed off the excess pumpkins, the only task left is to continue watering the plant until it has developed to the size and color you want. You can pick green pumpkins, because once off the vine they will become orange quickly, especially if you turn them into jack-o-lanterns. Smaller varieties will turn orange more quickly, and are ready to pick once they are orange. Once picked, the hard shell will keep the pumpkin good for several months. It is better to pick pumpkins earlier when your area starts to receive significant rain, as left on the vine they will begin to mold and rot.

The reason your pumpkins are only getting to be about the size of a golf ball/baseball is because they are not getting pollinated by the male pumpkin flowers. You need to snip off one of the males and rub the pollen onto a female flower while it is open (early in the morning is the best time for this). Once it becomes pollinated it begins to grow.

I have a question. I have around 6 plants that have taken over my back yard. It is now August and two pumpkins are completely orange and I have around ten more the size of basketballs that are green. and even more smaller ones the size of softballs and baseballs. Should I pick the two orange ones now or let them grow?

My pumpkin plant is growing strong with lots of big orange flowers that I see at least two bees every morning pollinating. I have had at least two small pumpkins try to grow but they have shriveled up and fell off. I have no pumpkins, just big orange flowers. What am I doing wrong or what can I do to help?

Holly, I've heard that the farther away from the plant the better - but I don't want to be the one that decides the pumpkin's fate!

On a side note, I had a strange thing happen with my pumpkin plant this year. There were about 25 total flowers - pretty good right? Except, *all* were female! All were tiny pumpkins, and there were *zero* males to pollenate. Has anyone ever heard of this? Was a shame to see all these little pumpkins die one after another. Sounds like an odd fluke.

Hi! We accidentally left our pumpkins outside through the winter, and surprise! We now have a pumpkin garden! My question is what can I use to protect them so that the small animals do not try to eat them, like the squirrels! Besides a fence, I had heard there is something we could spray on them, like a salad dressing or something? Look forward to your reply! -Stenuta18

Hi, I live in the UK so we don’t rely on the bees. If you get a female flower and a male flower, snip the male off, pull the petals of and then pollinate the female with the male, to make sure. All the best-- Malc—Rotherham - U.K.

We have our pumpkin plant and it is spreading beautifully. However, the small pumpkins that have started seem to rot right away, they are only about the size of a golf ball or smaller. Why does this happen? Michelle J - reno nv

I have had a poor season with not many female flowers per plant. One plant had just one female but over 10 male flowers. Is there any way to stimulate the growth of female flowers?

This is my first season growing pumpkins. We planted 5 jumbo seeds in 5 different mounds. Not sure they would all grow, Well they did! My husband and I continued to weed out the smallest of the vines until we were down to 3 plants. The seeds were planted middle of May and have been doing GREAT! We know have 24 pumpkins. I was reading a comment above that said the gentleman had never heard of a pumpkin growing so close to the main plant, Well our biggest pumpkin grew basically straight from the main vine where the seed was planted. So close I was unable to turn the pumpkin, if I tried to move it it would surely snap off. Anyways, I do have a question. The vines have done so much growing they are a good 30 ft from where I planted them. I have carefully untangled the vines and lined them to grow straight out. The problem may be that I used miracle grow (fr vegtables) n them. The majority of my pumpkins are hidden under the thick LARGE leaves. It is now middle of Sept and was wondering if I need to trim away some of the leaves so the pumpkins get more sunlight and are able to turn orange faster. Less than half of the ones hidden under the leaves are turning orange, they are just now starting to get a darker green and lines. The ones in the sun turned orange much faster. It is getting a bit cooler and rain has been more days lately. I live in Omaha, NE and it is starting to get cool at nights. I dont want them to get moldy. Thanks for ANY help! This whole summer has been a blast and has been so exciting! Amy Nobles

100% percent not true. You pollinate the female flower, and let it be - then the pumpkin grows. Sure the flower will fall off anyway, but it has nothing to do with whether it grows or not.

I don't know - I've heard that the best pumpkins grow on the offshoot vines (not the main vine), and I never heard of one so close to the main plant, but I wouldn't pinch it off... who knows you might not get another female flower in a while, and it's already August! I'd let it grow.

I was wondering a friend of mine told me that when your pumpkin gets a bloom on it to pick it or your pumpkin will not grow is this true?

Brad, Thanks for the nice comments. I wonder if it depends on the pumpkin plant type. The first year I tried, all I got was flowers, even though there are plenty of bees about to do the pollination. The next year, we planted two and Voila! pumpkins. Tricia

Great article, thank you so much for posting, however one part is inaccurate. You do _not_ need two pumpkin plants to grow a pumpkin. This actually steered me the wrong way for an entire afternoon because I was looking for another pumpkin plant of the same type and age since I became worried my plant won't grow pumpkins. Turns out, pumpkin plants have BOTH male and female flowers, so all it needs is itself! My pumpkin is growing as we speak and I only had one plant. So remember, only one plant is necessary!!! (although the more plants you have, the more likely a bee will come pollinate...)

our pumpkins have a small pumpkin and flower about an inch from the main plant. Should this one be pinched off? Looks like it is too close to the main plant. So far it is the only one on the plant.
