4 Squash Types to Grow with a Trellis

Trellising is a way of letting many squash types grow onto a frame of some sort, which immensely helps in saving space and can often be aesthetically pleasing. The frame can be constructed out of random materials, such as bamboo sticks and scraps of metal, and is ideal for climbing plants. Furthermore, trellising helps gardeners cover ugly patches in their gardens and can considerably add to a newer look. Below are some of the most popular types of squashes to grow on a trellis.

Spaghetti Squash

These squash types can be successfully grown straight with a trellis and are often “climbing” types of plants. They are winter squashes, but not because they are grown in the winters. They, instead, are called such because they can conveniently be stored for a long period of time and take longer to mature than summer squashes. Spaghetti squashes are aesthetically pleasing since they vine around trellises, weaving themselves completely in the process. 


Cucumbers are one of the most ideal kinds of squashes for growing on trellises since they have natural tendrils and do not need added support to stay on the frame. Cucumbers grown on trellises are less susceptible to damage. Trellises keep them off the ground and prevent diseases, including powdery mildew, to cause the fruit to rot. Additionally, the structure exposes the plant to maximum sunlight and optimal aeration, resulting in a healthier fruit.


Zucchinis can be effectively grown on a trellis. Zucchinis are summer squashes and do not spread entirely over the frame of a trellis as the winter squash types do. These have a more “bush-like” growth compared to the winter squashes and require more room to grow than many other types of squashes. Trellising a zucchini prevents diseases, insects and rot and yields healthier fruit than that produced by the ground sprawling variety. Zucchinis can be trellised on a vine trellis, rope trellis or a tomato cage.


Squashes such as pumpkins can be grown on a trellis regardless of their heavy weight. Special care would have to be taken to support them, and you can use a sling (t-shirt or an old piece of cloth) in order to do so. The squash can be placed within the sling and then attached to the trellis with care to let it be a part of the entire frame. Abundant supply of water as well as a sufficiently warm ground-temperature is a necessary requirement for growing such squash types. It would be wise to make sure that the trellis is firmly grounded so that the frame does not topple over under the pressure of these heavy-weight squashes. It is not a good idea to let these grow near the ground, as it makes them susceptible to insects. Trellising pumpkins saves valuable garden space and makes them an ideal plant for limited patches of green.
