How to Grow Zucchini on a Trellis

Zucchini is a garden crop that grows easily and abundantly for most gardeners. Growing zucchini on a garden trellis is an effective way of growing more in a small space because less ground space is used. It also is easier to watch for disease and pests, because the vines are up off the ground. In addition, harvesting zucchini growing on trellises is simple because the zucchinis are readily found growing along the sides. Learn how easy it is to grow zucchini on a trellis.

To grow your zucchini plants, choose a location that is on the northern side of your growing area. This will prevent the trellis from shading any of your other plants.

Pound the side trellis posts at least 2 feet into the ground to make sure the trellis will withstand the weight of the zucchini plants and blowing wind.

Plant the zucchini seeds at the base of the trellis approximately 1/2 inch under the soil. Space the seeds so there are two seeds about every 3 feet along the base of the trellis.

Keep the zucchini seeds evenly moist while they are germinating.

Watch the seedlings as they sprout and grow taller. As soon as they start touching the wire mesh of the trellis, begin encouraging them to grow in, out and around the wire mesh of the trellis. You can lightly tie the stalks to the wire mesh to train them, but this should not be necessary. The vines will naturally want to grow up the trellis.

Monitor the plant as it begins to flower and zucchinis begin to grow. Keep the plants well watered.

For best flavour, pick zucchinis before they grow to be 8 inches long. Zucchinis that grow on a trellis tend to be prolific, and you will need to monitor them daily to make sure they do not grow too large.


A simple 3-inch by 2-inch mesh that is attached and pulled between two side posts works very well for trellising zucchini plants.


Be sure to pick the zucchinis before they grow too large because they will weigh down the trellis unnecessarily.

Things You'll Need

  • Garden trellis (3-inch by 2-inch wire mesh and trellis posts work best)
  • Zucchini seeds (labelled "suitable for trellising")
