Do zucchini plants need a trellis to grow? We’ll talk about this today and also give you lots of tips on how to grow zucchini and summer squash.
Zucchini plants are a common plant in the home garden and a favorite of vegetable gardeners. They produce a lot of food, and grow quickly with little effort.
They do take up a lot of space, and are prone to fungal diseases and powdery mildew. Is growing them vertically a way to help prevent this?.
Zucchini is one of the most popular vegetables to grow in home gardens It’s easy to grow, productive, and versatile in the kitchen But should you provide support for your zucchini plants? The answer depends on the variety you’re growing.
An Overview of Zucchini Types
There are two main types of zucchini plants
Bush Zucchini
Most zucchini varieties are bush types. These have a more compact growth habit and don’t need trellising. Bush zucchini reaches 2-4 feet wide at maturity.
Popular bush zucchini varieties include Black Beauty, Gold Rush, Greyzini, Eight Ball, and Green Machine.
Vining Zucchini
There are a few vining zucchini varieties such as Tromboncino and Zucchetta Rampicante. These produce very long stems that can be trellised.
Vining zucchini is ideal if you want to grow vertically and maximize space. But the seeds can be harder to find since bush types are much more common.
Do Bush Zucchini Need Support?
Bush zucchini varieties do not require staking or trellising. However, some gardeners use short stakes or cages to support the large leaves and heavy fruits.
Adding minimal support can help:
- Improve airflow and sun penetration to reduce disease
- Make harvesting easier
- Keep fruits off the soil to prevent rot
- Support heavy branching stems
But bush zucchini generally grows and produces well without support. Go with your preference!
Provide Adequate Support for Vining Zucchini
Vining zucchini should always be trellised. The long, flexible stems can’t support the weight of fruits.
Use tall, sturdy trellises at least 5-6 feet high. Position trellises on the north side of plants so fruits grow into the sun.
Tie the main stems to vertical supports. Then weave or tie side shoots so the entire plant is supported as it grows.
You may need to use Velcro plant ties or soft twine so the tender stems aren’t damaged.
5 Tips for Growing Great Zucchini
Follow these tips for a healthy, productive zucchini crop:
-
Start seeds or transplants after danger of frost. Zucchini is a warm season crop. Sow seeds 1-2 weeks after your last expected frost date.
-
Plant in full sun. Zucchini needs at least 6-8 hours of direct sun daily.
-
Prepare soil well. Zucchini thrives in fertile, well-draining soil. Mix in several inches of compost before planting.
-
Provide sufficient water. Consistent moisture is vital. Water at the base of plants to keep leaves dry and deter disease.
-
Harvest frequently. Pick zucchini when 6-8 inches long. Regular harvesting keeps plants productive.
Consider Spacing When Planning Your Zucchini Patch
-
Bush zucchini can be spaced 1-2 feet apart in all directions.
-
For trellised zucchini, space plants 1-2 feet apart with 4-6 feet between rows.
-
Or plant bush zucchini 1 per square foot for a high-density garden. Just make sure to use plenty of fertilizer and irrigation.
-
Container zucchini should be alone in at least a 5 gallon pot.
Adjust spacing as needed based on your zucchini variety and available space. Crowding causes decreased growth and disease issues.
Help Prevent Powdery Mildew
Powdery mildew is a common zucchini disease. White powdery spots form on leaves in hot, humid weather. It eventually spreads to kill the entire plant.
To reduce powdery mildew:
-
Choose resistant varieties like Spineless Beauty.
-
Space plants adequately and improve airflow.
-
Avoid wetting foliage when watering. Use drip irrigation or soaker hoses.
-
Prune leaves showing early signs of the disease.
-
Use fans or mesh covers to keep humidity low.
-
Apply neem oil or potassium bicarbonate sprays preventatively.
Catching powdery mildew early and being proactive gives zucchini the best chance of survival.
-
Bush zucchini may appreciate minimal support but generally does fine without it.
-
Vining zucchini requires sturdy trellising from the start.
-
Account for mature plant size when planning spacing and supports.
-
Proper care and preventative measures help avoid disease issues.
How to grow zucchini in containers
Summer squash plants don’t have to take up a lot of space in your garden if you don’t want them to. You can grow zucchini and summer squash in a pot.
To have enough room, they need a big pot (5 gallons or more) and soil that drains well. Make sure there are adequate drainage holes.
When gardening in pots, you might need to water more often because plants in pots dry out faster than plants in the ground. You might also need to fertilize more often to make sure there are enough nutrients and that the water doesn’t wash them away.

How to Grow Zucchini on a Trellis
To get the most sun, you should plant your zucchini on the south side of a trellis cross. Center the main stem of the plant on the front of the trellis or vertical support.
You could also use rigid fencing or a tomato cage as a zucchini trellis. Just make sure that it is a strong trellis that is anchored in well to support the plant.
When you grow a bush type, it won’t grow long stems like most vining plants do. Instead, you can trim the lowest leaves of the plant, and tie the upper leaves to the support.
This creates better air flow, and is better suited for very humid environments. You will not need a tall trellis for bush varieties, 3-4 tall is probably suitable.
If you are growing a vine type, these will send out longer stems that you can tie or wrap around the trellis. You may want a taller trellis system as well, possibly 6 or more.
You might still want to cut back some of a vine plant’s lower leaves to let more air flow through.
