Do Zucchini Need A Trellis

Growing Zucchini: To Trellis or Not to Trellis?

A trellis is an architectural structure that allows vining plants to climb and grow vertically. It can be either metal or wooden, as well as in different shapes.

Using a trellis is beneficial, as it prevents various diseases and ensures that the plants grow straight.

Many plants require the use of a trellis, but others won’t flourish on it. So, let’s take a look at one common plant that people grow on a trellis: zucchini.

But does zucchini really need a trellis to grow?

Do Zucchini Need A Trellis?

Well, the answer is yes and no. It’s best to grow zucchini with a trellis since this plant is a climber. Because of that, it’s important to provide it with the right kind of support to ensure that it grows properly. With that said, the plant can fare very well on the ground as well. So, the trellis is optional.

Nevertheless, it’s crucial to give it support to prevent the branches from dropping to the ground and becoming dirty. So, you may want to go with a trellis anyway.

Why do zucchinis need a trellis?

The zucchini plant is a climber, which means that it needs some type of support to grow and flourish. Because of that, growing zucchini on a trellis is quite essential to give a place to climb.

In addition, zucchinis are heavy. This means that, without support, the branches might fall to the ground as a result of all the added weight.

So, it’s important to give zucchini plants a trellis for support, especially once it starts growing zucchinis.

On top of that, growing zucchini and other climbing plants on a trellis helps avoid various plant diseases and contamination from the soil.

Plant diseases, especially fungal ones, might attack the leaves, affecting how crisp and fresh the zucchinis will be.

Finally, growing your zucchini plant on a trellis helps you save space. As a vining plant, zucchini likes to spread. So, if you’re growing it on the ground, it might sprawl around your garden, taking up a lot of space.

So, trellising your zucchini plants is a great idea for many reasons.

How high does a trellis need to be for zucchinis?

To give zucchini sturdy support to climb, it’s best to go for a 6-foot trellis, either a metal or wooden one. This height will give your zucchini space to climb and attach its vines to the trellis for support.

With that said, keep in mind that you need to be able to reach the top of the trellis to check on the zucchini and harvest it.

So, it might be a good idea to make the trellis slightly shorter or equip yourself with a step ladder to reach the top.

Whatever way you choose to go about it, be sure to position the trellis so that it doesn’t block the sunlight to other plants you may have in your garden.

How do you grow zucchinis on a trellis?

Zucchini is a great plant choice for a trellis. It is very easily trained to climb and attached itself to a trellis, but it might need some help, especially at the beginning and once it starts growing zucchinis.

In the beginning, zucchini may want to naturally stay on the ground, sprawling around. So, you may need to pick up the vines and place them on the trellis to train them to go up.

After the zucchinis start growing, you may need to help the plant stay up since they are rather heavy.

Aside from that, growing zucchini on a trellis is very straightforward. 

What type of trellis is best for growing zucchinis?

Trellis for gardening

Zucchini grows best on either a metal or wooden trellis. 

There are many trellis varieties available on the market, and you can even construct your own using metal stakes or wooden posts.

When it comes to the shape of the trellis, there are many options you can choose from, depending on your preferences and the space you have available.

Choosing an A-shaped trellis can be the best if you don’t have too much space. This type of frame doesn’t take up too much space but still allows the plant to grow and climb without any interruptions.

You can also choose a completely vertical trellis. This type of support also saves a lot of space if you have other plants in your garden, as it prompts the zucchini plant to grow up and not to the sides.

So, as you can see, there’s no one specific type of trellis that you’re required to use for your zucchini plant. So, feel free to improvise and be creative.

Can you grow zucchinis without a trellis?

Even though it’s recommended to grow zucchini on a trellis, it’s not a requirement. The zucchini plant doesn’t need to climb in order to grow properly. So, you can get away with not having a trellis for this plant.

Zucchini is an easy plant to grow in a home garden. So, if you don’t have enough space for a trellis, you can pot it, and it will still grow without any problems.

So, it’s definitely not a requirement to use a trellis for the zucchini plant.

What types of zucchinis grow on a trellis?

Different types of zucchini

All zucchini plants like to climb, but they’re not as amazing climbers as cucumber or winter squash plants. Because of that, they may require some coaxing to attach themselves to the trellis and climb on it.

No matter what zucchini type you choose, you will find that this plant doesn’t have tendrils – the type of vine that helps plants climb.

Still, zucchinis fare really well on a trellis, regardless of what type you choose.

But if you want to go for a more trellis-friendly type of zucchini, you may want to look into winter squash, which is a plant very close to zucchini.


In general, it’s recommended to grow zucchini on a trellis, but it’s not a requirement. Even though the zucchini plant is a climber, it can grow without any problems on the ground or in a pot.

So, whether you choose to use a trellis for your zucchini plant or not depends on your preferences and how much space you have in your garden.
