Save Space

As discussed above, squash and zucchini plants occupy a lot of space. These plants cannot hold themselves upwards and usually flop down due to the heavy weight of the fruits.

This makes them take over a garden rather quickly and makes it impossible to grow other plants, especially if you are short on space. Therefore, growing these plants vertically in tomato cages or trellises gives them the support they need to remain in an upward position.

Reduce Chances of Rotting and Disease

Since zucchini and squash plants flop to the ground, they come in direct contact with the moisture in the soil. This makes these plants vulnerable to rotting, especially during winter, when the soil may take longer to dry after watering.

When the foliage of these plants stays wet for long periods, it can be susceptible to developing fungal diseases. If the fungal disease spreads on your entire crop of zucchini and squash plants, it may become almost impossible to contain.

The key to avoiding these issues is to keep the foliage from touching the ground. Therefore, growing squash and zucchini vertically is a great way to reduce the likelihood of the plant rotting and becoming diseased.

Keep Pests and Rodents Away from The Plants

When plants touch the ground, they become a direct invitation for rodents and pests looking to munch on a delicious meal. Controlling pest damage can be difficult, especially if it spreads to your entire crop.

Moreover, nobody likes to see chunks missing from their freshly harvested crops. Thankfully, by growing your zucchini and squash plants vertically, you can reduce the likelihood of facing these issues.

However, remember that growing zucchini and squash vertically does not guarantee that our plants will never suffer a pest or rodent attack. So ensure you take preventative measures to avoid pest and rodent infestations and watch your plants for signs of such issues.

Simplify The Harvesting Process

Harvesting Zucchini and squash plants can be a nightmare when growing them horizontally. You have to go through the hassle of bending down and lifting each vine to look for the fruit. Furthermore, it can be easy to miss some fruits when they are covered in foliage.

Growing these plants vertically can make the task of harvesting so much easier. You can easily see the fruits hanging from vines, making the harvesting process simple and enjoyable. 

Provide Better Lighting to The Plants

Both zucchini and squash plants thrive in the sunlight. These plants demand at least six to eight hours of full sun daily.

The tendency of these plants to flop down on the ground may make it difficult for them to absorb adequate sunlight due to shading. In contrast, when grown vertically, the plant’s foliage is evenly spread out, allowing the sunlight to hit more parts of the plant.

How to Train Squash and Zucchini Plants to Grow Vertically

How to Train Squash and Zucchini Plants to Grow Vertically

Follow the steps below to train Zucchini and squash plants to grow vertically:

1. Begin from Seed

When training a zucchini or squash plant to grow vertically, it is always advisable to start from seed. Although it is possible to train zucchini and squash plants to grow vertically when grown horizontally from the start, it can be a complex undertaking.

Hence, training them to grow in a vertical position when they first begin to develop foliage is the easiest way to grow them in an upward position. 

2. Pick A Compact Variety

When growing zucchini and squash plants vertically, it is important that you choose a variety that grows in a slightly contained manner. Some smaller varieties of zucchini plants include:

  • Spacemiser
  • Bush Baby
  • Gold Rush
  • Eightball
  • Sunscreen
  • Raven
  • Black Beauty
  • Eight Ball

Compact varieties of squash plants include:

  • Horn of Plenty
  • Honey Baby
  • Sugaretti
  • Sugarbush
  • Reno Acorn

3. Grow The Plants in Full Sun

Zucchini and squash plants enjoy ample amounts of full sun. So when growing these plants vertically from seed, give them as much sunlight as possible to accelerate the growing process.

Buy Appropriate Potting Mix

One factor to consider when growing zucchini or squash vertically is that, in some situations, you have to plant the seeds in a container with the help of a potting mix instead of directly planting in the ground.

This usually depends on the support system you use for the plants. For example, if you are growing your zucchini or squash plants in pouches, you may have to sow the seeds in the pouches instead of the ground.

Therefore, you must purchase high-quality and nutrient-rich potting mix to help give the seeds the nutrients they require to sprout. In contrast, if you support the plants with a trellis or tomato cage, you can directly sow the seeds into the ground.

4. Plant A Single Seed for Each Slot

You can plant several seeds at once when growing zucchini and squash in the ground and supporting them with support systems like trellises.

However, continuing the example discussed above, you will want to stick to planting one seed in each pouch, when growing in pouches. This is because it can become tough to thin out the plants once they grow.

Doing so will also allow every plant enough room to grow and ensure adequate air circulation.

Care for The Plants and Guide Them to Grow Vertically

Once you have planted your zucchini and squash plants, all that is left is to wait for them to grow vines and guide each vine to grow vertically. You can use jute ropes to tie each vine upwards to the trellises or tomato cage.

Moreover, some important care measures include watering the plant regularly, ensuring the soil remains moist as it grows, and harvesting immediately once the fruits are ready to encourage the plants to grow more fruits and keep things from getting messy.

Water your zucchini and squash plants downwards, and avoid getting the foliage wet. Wet foliage increases the risk of the plant developing fungal diseases like powdery mildew.

Offering adequate ventilation and watering the plant in the early hours is the key to avoiding fungal growths on your plant. Doing so allows plants to become dry until night. Watering at night may cause the plant to remain wet for longer, increasing the risk of fungal infections.
