Fall is the time of year when we pull out the sweaters and boots, add a jacket to our attire and immerse ourselves in all things pumpkin. From creamer to donuts to home decor, pumpkins represent autumn from when the first leaf falls to long after the Thanksgiving dishes have been dried and put away. Of course, there is also the age-old practice of carving pumpkins for Halloween. While every supermarket has mounds of pumpkins ready for purchase, with a little planning you can grow and harvest your own pumpkins for everything from jack-o’-lanterns to pumpkin bread.
By the time October hits, all you can really do is plan for next year’s garden (which is a great idea!). Seeds should go into the ground between the end of May and mid-July, depending on where you live. Be sure you don’t plant too early in the season. Although the plants will thrive and produce fruit happily throughout the late summer and early fall, you may find yourself with rotten fruit before the pumpkin-carving party if they ripen months beforehand.
Pumpkin plants ramble. In fact, they will take over and may cause problems if confined, so give them a dedicated area to thrive. This is not a plant that will be successful on an apartment balcony. Allow them ample room to bush out without running into other garden crops, outbuildings or fencing. For planning purposes, set aside around 9-10 feet in each direction for each mound of plants (around 100 square feet).
Mound it up
Rounded mounds of soil provide the drainage and depth pumpkins need to thrive. Pumpkin seeds and vines are finicky, so you don’t want to handle or transplant them once they are in soil. To avoid disturbing them, make sure your mounds are established before planting. Set them at least 5-6 feet apart from each other.
Let it shine
When choosing the location for your pumpkin mounds, select a space that receives a lot of sunlight. Pumpkin seeds don’t do well in cold soil or dirt that is too wet. They prefer a warm environment, so choose your selection with that in mind.
Choose preferred varieties
There are many varieties of pumpkins, some that look more like squash in shape and color. In fact, many people use the labels squash and pumpkin interchangeably. There are also a variety of sizes, from small decorative options to giant, 100-pound versions. Choose your seeds well to match the space you have available.
Make them share
Pumpkins grow well in clusters. To find the strongest plants, plant five or six seeds per mound. Seeds should be pressed into the soil about one inch deep and lightly covered. Once they are well-established, thin to the healthiest two to three plants per mound. Each plant will produce multiple pumpkins.
You can see the potential when the plants bloom flowers. Soon, each of those flowers will have a pumpkin behind it beginning to form. Be mindful though — only female flowers produce fruit. The male flowers bloom briefly, giving bees an opportunity to find the flowering vines. Then, they drop off the plant. Female flowers, however, will show the bulb of the green emerging fruit behind them.
Keep the weeds out
Weeds can choke out the productivity of your pumpkin plants, so keep them at bay by frequently checking for new growth and removing them early on. A hoe works well for this task to avoid the back and knee strain from getting on the ground. Try not to dig too deep, which could interfere with the roots of the pumpkin plants. Avoid harmful weed killers anywhere near your plants (and preferably your entire yard). Applying mulch to pumpkin plants will help keep the weeds away and hold the moisture in.
Stick to a watering schedule
Pumpkins are fairly forgiving of a little neglect when it comes to water, as long as they have a chance to get established with reliable drinks. Give them a drink at least once each week, saturating the soil around the base of each plant while avoiding leaves and fruit wherever possible. In the beginning though, avoid flooding the seed and seedlings as they become established. Instead, give them shallow drinks. Schedule an extra watering if the weather is extreme during the early summer growing season.
You won’t have to dote on your growing pumpkins too frequently. Given the right location, soil and temperature, they are pretty self-sufficient. If you are planning to use your pumpkins for carving, you may want to gently rotate them occasionally. This will help avoid pumpkins with a flat side and help them grow into a more uniform shape; however, the vines are persnickety, so use caution or the vine may be damaged. Tip: Set each pumpkin on a piece of cardboard and gently rotate it every few weeks for even heat and light.
Your pumpkins will likely be ready to harvest during the last two weeks of September. They are ready when the stem is firm and the pumpkin turns from green to deep orange. Cut the stem carefully as most have sharp prickles. Use gloves and a sharp blade. Leave around 3-4 inches of stem attached to the pumpkin. You can leave the pumpkin attached to the vine, or cut it and leave it outside. However, if freezing weather is coming, cut your pumpkins and store them in a cool, dry location. Use as soon as possible for decor or your favorite recipe.
