The only thing I love more than our annual trip to the pumpkin patch each fall is being able to harvest our own pumpkins right in our garden. Sugar Pie pumpkins, French heirlooms, Jack-O-Lanterns, white Luminas… there are so many varieties to choose from, and learning how to grow pumpkins from seed at home allows you to grow types that you might not find at your local pumpkin patch (and ones you certainly won’t find at your average grocery store!)
Because pumpkins do require plenty of space to grow, they’re probably not the best candidate for a small space or container garden on your balcony. If you’ve got room for a garden, then be sure to make room for your own backyard pumpkin patch because these fall fruits (yes, they are technically a fruit!) are fun, easy, and rewarding to grow at home.
Selecting pumpkin varieties for your home garden
When considering the best pumpkin varieties for your garden,the ones you choose will depend on whether you’re looking for a good pie or eating pumpkin, a large carving pumpkin for Halloween or something more unique and decorative.
Just to clarify, all pumpkins are technically edible, however some varieties have a lower sugar content and a higher water content, making them less flavourful and appealing, but good candidates for carving and decorating.
If you’re just getting started growing and using pumpkins at home, here are a few of the varieties I recommend.

Pie Pumpkins
If you’re looking for a good pumpkin formaking pumpkin pie, sugar pumpkins (aka. sugar pie or small sugar pumpkins) are the quintessential pumpkin pie pumpkin (hence the name).
These pumpkins have a high sugar/low water content and are excellent in all sorts of fall baking dishes as well as savoury pumpkin dishes like pumpkin soup or pumpkin ravioli.
There are many good eating pumpkins, but this is definitely one of the most popular for cooking and baking.
Carving Pumpkins
If, however, you’re looking for a good carving pumpkin with bright orange flesh, you’ll want to opt for a larger variety like a Jack-O-Lantern. You could also try a white pumpkin called Lumina if you’re looking for a unique carving pumpkin. A tip to avoid confusion: if you’re looking for Jack-O-Lantern seeds, some seed companies simply call them Jack-O-Lantern seeds while other companies sell varieties of Jack-O-Lantern seeds such as Wolf Pumpkins and Early Giant Pumpkins.

Unique Heirloom Varieties
If you want something a little different, there are some really cool heirloom varieties that are as visually stunning as they are delicious. Some that I recommend include the French “Rouge Vif d’Etampes” (aka. Cinderella Pumpkins), “Galeux d’Eysines” and “Musquée De Provence,” as well as Long Island Cheese and Flat White Boer pumpkins.
A ‘heads up’ about pumpkin seeds
It’s a good idea to always start with organic seeds from a reputable source. Since I live in the Pacific Northwest, I like to get almost all of my seeds fromWest Coast Seeds(not an affiliate… I just love this company).
But there are lots of great seed companies out there, and I always recommend going local, especially when it comes to seeds because they’ll be better acclimated to your growing area. Check out your local farmer’s market or garden store for a good local seed company in your area. They’ll be sure to have plenty of beautiful and unique pumpkin varieties!
Also, don’t bother trying to save seeds from pumpkins you bought at the grocery store or got at the pumpkin patch. While those seeds are perfectly fine for roasting and eating, different pumpkin varieties (and even squashes) are notorious for cross-pollinating with each other. The plant that grows from one of those seeds likely won’t turn out to be quite what you’d expect it to be, but rather a fish-mash between two different varieties of parent plants. These “hybrid” offspring usually aren’t very good to eat either.
Sugar pumpkin/spaghetti squash hybrid.
Case in point, we had a volunteer pumpkin grow in our garden last year from a seed that had been in our compost. We had been growing a mix pumpkins and spaghetti squashes in our garden the season before, so the resulting plant had the colouring of a pumpkin, the shape of a spaghetti squash, and the flavour and texture of neither.
Moral of the story: start with good quality seeds. Then it’s time to start planting 🙂
How to grow pumpkins from seed
The Basics:
- Choose a location with well-drained soil that gets full sun and lots of room for pumpkin vines to sprawl out.
- You can start seeds indoors or direct sow pumpkin seeds.
- If you live in a cold climate, start seeds indoors 3 to 4 weeks before the last frost to give pumpkins enough time to mature, as they do require a long growing season.
- If you live in a cool/temperate climate, start seeds indoors 3 to 4 weeks before planting out OR direct sow them in late spring(May/early June.)
- In warm locations, direct sow seeds all the way up to mid July for a fall harvest.
- Add some finished compost, composted manure or organic fertilizer to each mound before planting.
- Plant in hills or mounds that are 5 or 6 feet apart.
- If direct sowing, plant seeds 1 inch deep. Plants should germinate in 5 to 10 days.
The Details:
Pumpkin seeds germinate easily, but they require a warm soil temperature, so depending on where you live, you may or may not want to start seeds indoors to give them a jump on the growing season.
Most of the time, the best way to sow pumpkin seeds is to plant them directly into your garden so as not to disturb their roots when transplanting. Wait until the soil warms up to 70-95ºF (25-35ºC).
In cooler climates and northern locations, direct sow pumpkin seeds a few weeks after your last frost date once soil has warmed up and all danger of frost has passed (usually late May/early June), or start seeds indoors 3 to 4 weeks before your last frost date if you’ve got a really short growing season.
If you live in a warmer climate, you can plant all the way into July for a fall harvest.
Pumpkins require a long growing season, typically needing about 75-100 frost-free growing days.The seed packet should tell you the approximate days to maturity of specific pumpkin varieties. If you’re not sure when to plant, check the last and first average frost dates for your area and calculate the number of days in between to determine the best time to start seeds and whether to start indoors or direct so them.Click hereto find the first and last average frost dates for your location.
If you do start pumpkin seeds indoors, the best way is to grow them in newspaper pots orpeat potsso that when it’s time to transplant the young plants, you can place the entire pot into the soil without disturbing the plant’s roots.
Pumpkins are heavy feeders that require plenty of space, warmth, and sunlight while growing. Choose a sunny spot (full sun if possible, or at least only partial shade) with enough room for pumpkin vines to grow. Add in some compost or organic fertilizer to each mound before planting.
Plants also do best in areas with well-drained fertile soil, so creating mounds or hills will help to ensure good soil drainage and will also help keep soil warmer than the soil deeper in the ground.
Space mounds at least 5 to 6 feet apart in order to allow enough space for vine growth. Direct sow pumpkin seeds 1 inch deep. To ensure good germination rates, plant 3 or 4 seeds per mound and thin them out to the strongest plant as they begin to grow. If transplanting seedlings, plant one per mound.
How to Care for Pumpkin Plants
The Basics:
- Keep soil around pumpkin plants well watered but try to avoid getting the leaves wet.
- Mulch around pumpkin plants to keep soil moist and keep weeds at bay.
- Feed pumpkin plants a weekly dose of nitrogen-rich fertilizer for best results.
- As pumpkins begin to grow larger, gently rotate them so that the same side doesn’t remain laying on the ground. This helps ensure more evenly rounded pumpkins.
- You can train vines up a trellis if you’re growing a small pumpkin variety and are short on space.
- Pumpkins need bees and other pollinators for cross-pollination, so do what you can to encourage bees into your garden and as always, refrain from using pesticides!
The Details:
Pumpkins require lots of water but they don’t like to get their leaves wet. Water plants deeply right at the soil line once a week and keep the soil damp, but try to avoid watering from overhead in order to keep the leaves dry. Setting up a drip irrigation system can help with this.
Mulch around the pumpkin plants to help keep the soil moist and keep weeds from growing. Hand weed any weeds that do pop up so that they don’t compete for nutrients.
Pumpkins are also heavy feeders, and require very fertile soil. Fertilize regularly by applying a nitrogen-rich fertilizer (such as well-rotted manure) weekly for optimum results.
As pumpkins grow, rotate them very gently to encourage even colour and roundedness. If you’re trying to grow large or giant pumpkins, consider pinching off any other tiny fruits that begin to form so that all of the energy goes into producing the single fruit on each vine.
You can also prune vines in order to direct more energy into the fruits or if you’re short on space. Another option for small spaces is to train pumpkin vines up a trellis. While all vines can technically be trained up a trellis, it’s obviously easier to do this with small pumpkins as the fruits aren’t as large and heavy.
Also, refrain from using herbicides and pesticides (for obvious reasons), however especially because pumpkin plants are dependent on bee pollination. Encourage bees into your garden by companion planting flowers and perhaps even consider setting up aMason bee “hotel.”
How to Harvest and Store Pumpkins
The Basics:
- Harvest pumpkins when they’re mature and have fully turned orange (or whatever colour they are meant to be).
- Harvest mature fruit during dry weather once the vines have begun to die back.
- Cut pumpkins off the vine with a sharp knife or pruners. Leave a few inches of stem.
- Cure pumpkins off the vine in the sun for a week or two to harden up the skins. Then transfer to a root cellar or cold room.
The Details:
Wait until pumpkins are fully mature before harvesting. If you harvest pumpkins too early and they’re still green and developing, they won’t be good to eat and they won’t continue to ripen off the vine like some fruits do, so be patient. Pumpkins are ready for harvest when the vines begin to die back (when they start to dry up and stop growing) and the pumpkins turn solid orange, or whatever colour they’re meant to be when fully mature.
At the same time, don’t wait too long to harvest them in the fall. A hard frost can cause pumpkins that have been left on the vine to rot once they thaw out.
Harvest mature fruit during dry weather. Cut pumpkins off the vine with a sharp knife orpruners. Do not rip or tear them off as this can leave jagged ends on the stem that invite disease that could rot your pumpkin. Leave a few inches of stem.
Pumpkins store well for long periods of time if they are cured well and stored in the right conditions.For best results, cure pumpkins in the sun for a week or two to harden and thicken up the skins, then transfer to a root cellar or cold room.
If the weather turns or you can’t cure them outside for any reason, you can cure them inside. Try to cure them in a warm, sunny place indoors, like near a sunny window. Store in a cool place if you don’t have a root cellar. A garage works well or if nothing else, pop them on the floor or bottom shelf in your pantry.
Pumpkins last months when cured and stored correctly so they’re a great candidate for preserving through the winter, especially since you don’t have to do much to preserve them!
However, they can be a bit finicky to cut up and prepare. To save time while cooking (and make your pumpkins shelf stable for a much longer period of time),learn how to can pumpkin at home.
