Why Should I Grow Pumpkins Vertically?

Pumpkin vines have a tendency to sprawl and take up a lot of space in the garden. By growing pumpkins vertically, you can save space and ensure better airflow and fewer pest problems. Additionally, vertical gardening can help prevent diseases and rot by keeping the fruits off the ground. It’s also a great way to prevent vines from smothering other plants in your garden.

What Type of Trellis Should I Choose?

There are several types of trellises you can use to train pumpkins to grow vertically. Here are some popular options:

DIY Trellis

If you’re handy with wood, you can create your own trellis using materials like U-posts and nylon netting. This type of trellis works well for small and medium-sized pumpkins and other gourds.

Pea Fence

A pea fence is a tall, foldable trellis that works well for smaller pumpkin varieties. It’s also suitable for medium gourds like ‘Triple Treat’ and ‘Jarrahdale’.

Tomato Cage

A tomato cage can make an excellent trellis for pumpkins. Look for a tall cage that can support the weight of the fruits. This type of trellis is suitable for smaller varieties like ‘Jack be Little’, ‘Small Sugar’, and ‘Orange Smoothie’.

Trellised Arbor

For a more decorative option, consider using a trellised arbor. This type of structure features growing boxes on each side, making it easy to plant gourds and train the vines to grow through the latticework on the sides of the arbor. It can support heavier gourds like ‘Howden’, ‘Musquee de Provence’, and ‘Jack-O-Lantern’.

Training Young Plants to the Structure

When planting pumpkins with the intention of growing them vertically, there are a few key steps to keep in mind. If you live in Zones 7 and up, you can direct sow your seeds next to your trellis after the last average frost date. Keep the seeds moist until germination, which should occur within five to 10 days.

For Zones 3-6, you may need to sow seeds indoors in biodegradable peat pots. Once the plants have two to three true leaves, transplant them outdoors next to the trellis. When training young vines, use gardening ties or twine to secure them to the structure. Monitor the vines daily and continue to train them vertically as they grow.

Supporting the Fruit

To prevent the vines from collapsing under the weight of the fruits, consider using a netted sling to support them. Alternatively, you can use whatever materials you have on hand to provide additional support to the vines. By supporting the fruits, you can ensure a successful harvest of pumpkins grown vertically.

In conclusion, training pumpkins to grow on a trellis can be a practical and effective way to manage your garden space and improve airflow and pest control. By choosing the right trellis and following proper training techniques, you can enjoy a bountiful harvest of pumpkins without the hassle of unruly vines taking over your garden.
