How to Grow Pumpkins on a Trellis

By Nouman F

Years ago, I stumbled upon dreamy images of vertical gardens on Pinterest. I promised myself that one year, I would make this vision a reality. This year, that someday finally arrived, and I constructed my first vertical pumpkin trellis.

Last garden season, we grew pumpkins for the first time and watched them sprawled across our small space. This summer, I decided to start growing them vertically for a variety of reasons. It’s amusing to recall the cute bamboo hoops I set up for my pumpkin plants. As a novice with the Cucurbits, I thought their vines would curl around the tiny bamboo hoops and produce precious, delicate gourds.

If you’ve ever grown pumpkins, you know how wrong I was. Initially, the attractive hoops worked just fine. The young vines grew slowly, and I used gardening ties to secure them, admiring their gentle beauty.

Pumpkins are versatile crops, perfect for pies and decorations. If your garden is short on space, a trellis is an efficient way to grow them vertically and achieve a bountiful harvest without taking up too much room.

How to Grow Pumpkins on a Trellis

Growing pumpkins on a trellis offers numerous advantages, such as optimizing space in small gardens and enhancing air circulation, which helps prevent diseases and pests. This vertical gardening method makes harvesting easier and keeps the pumpkins cleaner by lifting them off the ground, reducing the risk of rot. To set up a pumpkin trellis, you need a sturdy structure like a hog panel secured with T-posts. Properly supporting the vines with bamboo hoops or plastic trellises ensures they grow healthily.

Choosing the right pumpkin variety, such as Small Sugar or Jack Be Little, and preparing nutrient-rich, well-draining soil are crucial. As the plants grow, tie the vines gently to the trellis and prune excess growth. Regular watering and bi-weekly fertilizing support robust growth. Harvesting involves cutting the pumpkins with a bit of stem attached to prevent rot. This method, inspired by experts and shared experiences, proves efficient for maximizing garden space and maintaining healthy pumpkin plants.

Benefits of growing on a pumpkin trellis

Growing pumpkins on a trellis offers several benefits. One of the main advantages is maximizing space in a small gardening area. This method allows you to grow more crops and plants by saving space. Additionally, it improves air circulation, which helps to prevent disease and pests.

Harvesting pumpkins on a trellis is much easier and less back-breaking compared to picking them from the ground. The pumpkins are also cleaner, as they are kept off the ground, reducing the risk of rot and other diseases. Although the vines might still spread out, using multiple trellises can help manage this.

In my garden last August 2023, I decided to make a pumpkin trellis after seeing dreamy images of vertical gardens on Pinterest. I had promised myself for years that I would try it someday. Growing pumpkins vertically not only saved room but also provided more chances for the vines to breathe and circulate air. This reduced the likelihood of blight, fungi, and common pests like squash bugs, which usually hide among the plants.

Growing on the pumpkin trellis

Growing pumpkins and gourds on a pumpkin trellis has transformed my garden. I started by growing the seeds in the basement and then moved them to the greenhouse. Over the years, I’ve come to appreciate the benefits of vertical gardens. The idea came from Pinterest, and I promised myself that someday I would try it. Now, in our small space, we grow pumpkins vertically for several reasons.

Firstly, growing vertically saves room and improves air circulation around the vines, reducing the risk of disease like blight and fungi. It also limits hiding spots for destructive bugs like squash bugs, which are a common nemesis for squash plants on the ground. With fewer places to hide, these bugs are less of a problem.

My Personal Experience

My Friend provided me with detailed instructions on building vine trellises. I grow a variety of pumpkins, including Casper Pumpkins, Bird House Gourds, and Little Jack Pumpkins. He taught me to support the heavier pumpkin vines with a bamboo hoop or a plastic trellis.

Our Little Jacks are the main pumpkins on the trellis, and it’s been fun seeing them grow. The vines can reach 10 to 20 feet, so proper support is crucial. Pumpkin companion plants like cucumbers, tomatoes, and zucchini thrive well alongside. In my raised bed, I also plant peas with white blooms that produce green pods.

This vertical gardening method keeps the soil from getting soggy and bug-infested. Sharing this journey on Instagram with a community of talented ladies in the farmhouse circle has been a real pleasure.

Things you need for a pumpkin trellis

Growing pumpkins on a trellis can be a fun and rewarding way to save space in your garden. Pumpkins can thrive when grown vertically, providing many benefits such as better air circulation and reduced risk of disease. Here’s a guide on what you need to create a pumpkin trellis.

Supplies You Need

For a pumpkin trellis, you’ll need some heavy-duty supplies. Start with a hog panel, which you can find at farm supply stores like Tractor Supply, Farm and Fleet, Home Depot, or Menard’s. If you live in populated areas, these stores might even ship the paneling to you. During the pandemic, many stores have prepared for pick up or deliver services. A hog panel is typically 16-feet long and 34 inches wide, making it sturdy enough to hold large pumpkins.

Setting Up Your Trellis

To set up your trellis, you’ll need Metal T-posts which you can buy from home improvement stores. You’ll need four 4-feet tall T-posts, along with steel heavy duty T-post clips, a screwdriver, and pliers. The posts need to be driven into the ground about 6 inches deep. It’s best to have two people to help twist and secure the cattle panel to the posts. Be sure to use caution and ensure everything is firmly in place.

Tips and Tricks

Consider using watermelon hammocks to support the weight of the pumpkins. These hammocks help prevent the fruit from getting too heavy for the vines. If you’re growing pumpkins in pots, make sure the pots are large enough to accommodate the pumpkin vine, which can grow 10 to 20 feet long.

Adding vine trellises can also support other vining plants like cucumbers, tomatoes, and zucchini. Vertical gardening allows your plants to have more room to breathe, reducing the likelihood of issues like blight and destructive bugs like squash bugs.

Growing pumpkins vertically has been a game-changer in my gardening journey. Last year, I studied how to properly set up my trellis, and the results were fantastic. My pumpkins thrived, and I even had room to plant Little Jack Pumpkins, Casper Pumpkins, and Bird House Gourds. It was a pleasure to watch my garden flourish vertically.

Choosing the Right Pumpkin Variety

  • In my vertical gardening adventure, I learned it’s important to choose the right type of pumpkin for your trellis.
  • Some great varieties include Small Sugar, which are smaller and lighter, making them easier to support.
  • Jack Be Little is perfect for small gardening spaces and decorations.
  • Cinderella has a flattened shape that’s perfect for stacking.
  • Big Max pumpkins are larger and require a sturdy trellis, but they’re worth it for the massive size of the final fruit.
  • Sugar Pie pumpkins are great for baking with their smooth, sweet flesh.

Preparing the Soil

Once you’ve chosen your pumpkin seeds, it’s important to prepare the soil properly. Pumpkins need well-draining soil that is rich in nutrients. Here are some tips to get your soil ready: start by tilling the soil to a depth of at least 12 inches. Add compost or aged manure to improve its nutrient content. Finally, mix in a slow-release fertilizer to provide your pumpkin plants with the nutrients they need to grow strong.

Building the Trellis

The key to successfully growing pumpkins on a trellis is to provide enough support for the vine. Here are some tips for building a sturdy trellis: Use sturdy materials like wood or metal; PVC pipes can work but aren’t as strong. Ensure the trellis is at least 6 feet tall to accommodate the height of the pumpkin vine. Space the trellis about 4-5 feet apart to give the pumpkin vine enough room to grow.

Planting the Pumpkin Seeds

After you’ve built your trellis and prepared the soil, it’s time to plant the pumpkin seeds. Plant the seeds about 1 inch deep in the soil. Make sure the soil is moist but not soaking wet. Space the seeds about 3-4 feet apart to give each plant enough room to grow.

Supporting the Vine

As the pumpkin vine grows, it will need support to prevent it from falling off the trellis. Use garden twine or ties to tie the vine to the trellis as it grows. Ensure the ties are not too tight to allow room for growth. Use pruning shears to trim any excess growth that is not needed.

Watering and Fertilizing

Pumpkin plants require regular watering and fertilizing to grow strong and produce a good harvest. Here are some tips: water the plants regularly, making sure the soil stays moist but not too wet. Fertilize every two weeks with a balanced fertilizer. Be sure to follow the instructions on the fertilizer package to avoid over-fertilizing.

Harvesting the Pumpkins

Once your pumpkins have grown to maturity, it’s time to harvest them. Cut the vine using pruning shears or a sharp knife, leaving about 2-3 inches of stem attached to prevent rot. Let the harvested pumpkins cure for a week in a warm, dry place before using or storing them. Always check the pumpkins for any signs of damage or rotting before storing.

Benefits of Growing Pumpkins Vertically

Growing pumpkins on a trellis offers numerous benefits that make this method a smart choice for maximizing your garden space. When gardening in a small area, this approach not only allows you to grow more plants and crops, but it also improves air circulation around your vertical garden. By growing pumpkins vertically, you can prevent disease and pests, leading to a healthier harvest.

Additionally, harvesting becomes much easier and less back-breaking since you don’t have to bend down to pick the fruit. Another advantage is that the pumpkins stay off the ground, which keeps them cleaner and reduces the risk of rot. This method is perfect for anyone looking to save space while enjoying a bountiful and healthy harvest. Grow cucumbers using a trellis in a similar way to enjoy the same benefits.

What Type of Trellis Should I Choose?

When choosing a trellis for your pumpkins, there are several options to consider. If you’re handy with wood and enjoy DIY projects, you can fashion a trellis using U-posts and nylon netting. Simply drive the posts five feet apart and 12 inches deep in your garden, then use heavy-duty scissors to cut the netting to size. Fasten it with zip ties. This classic, ground-level structure is great for small and medium-sized gourds. For those with raised beds or containers, place the structure behind the bed or anywhere you like.

A pea fence is another excellent option, especially for those looking for a taller structure. This eight feet foldable panel works well for smaller and medium pumpkin varieties, such as ‘Triple Treat’ and ‘Jarrahdale.’ If you prefer a tomato cage, these are also effective.

I’ve personally used a tomato cage to train a cantaloupe vine, and it worked wonderfully. For smaller pumpkins like ‘Jack be Little,’ ‘Small Sugar,’ and ‘Orange Smoothie,’ a 54-inch cage from Home Depot is ideal.

For an enchanting arch covered with strong, vibrant vines, consider an arbor. This type of structure can support even the heavier gourds like ‘Howden,’ ‘Musquee de Provence,’ and ‘Jack-O-Lantern.’ An arbor from Home Depot, standing at 82 inches tall and 23 inches wide, with a box on each side for planting, creates a beautiful entrance to any garden or yard. The latticework on the sides helps train the vines perfectly.

Training Young Plants to the Structure

Growing pumpkins on a trellis can save space and make your garden look beautiful. Start by direct sowing the seeds in one-inch holes in the soil after the last average frost date when there is no freezing weather forecast. If you’re in USDA Hardiness Zones 3-9, especially Zone 7, this is the ideal time.

Keep the seeds moist to encourage germination within five to ten days. Once you see the true leaves, start training the vines to climb the structure.

If you live in Zones 3-6, sow the seeds indoors in biodegradable peat pots. When the plants have true leaves, transplant them outdoors by digging a hole in the earth the same size as the pot, and then place the plant inside with the peat pot.

For those who prefer buying young plants from a nursery, dig a hole deep and wide enough for the pot, carefully remove the plant, and place it in the hole. Backfill with soil and water thoroughly.

As the young vines grow, they can be floppy. Gardening ties or twine from places like Home Depot can help. Tie the vine to the trellis, making sure it’s not too tight, allowing it room to breathe and grow. Weave the vines through the lattice or use nylon netting to keep them secure and prevent them from falling.

Check the vines daily to monitor for pests and disease. This also helps in training the vines as they grow vertically. Long, tangly vines can be harder to retrain, so regular attention is crucial. By keeping your flowers tidy, you provide space for bees to pollinate naturally, but you can also hand pollinate if necessary. This ensures your heirloom pumpkins have the best chance to grow successfully.

Tips for Success

Growing pumpkins on a trellis is a unique strategy that requires careful attention to details for success. Ensure your pumpkin trellis is placed in a sunny location to provide your plants with adequate light, which is essential for healthy growth. Make use of a drip irrigation system to water the vines; this approach helps keep the water focused at the roots and prevent diseases by avoiding wet foliage.

Regularly check the trellis to make sure it’s sturdy enough to support the weight of growing pumpkins. Also, prune the pumpkin vine to encourage growth and prevent overcrowding, which can affect the overall health and yield of your pumpkins. This guidance comes from my own experience in maximizing garden space and ensuring the health of climbing plants.
