Zucchini and summer squash take up a lot of space in the garden, so it's a little challenging to find plants that work well with them. They tend to be heavy feeders, and require regular, even watering. With that in mind, here are three plants that work well as companion plants for zucchini:
- Corn: Corn shares space well with zucchini and summer squash, since it grows vertically and the squash grow along the ground. The squash plants also help shade the soil to reduce the amount of weeds that compete with the corn plants. Both corn and summer squash have the same moisture and soil fertility requirements, so they are very good neighbors.
- Beans: Pole beans, especially, work well planted near zucchini and other summer squashes. They can be trained up a trellis, and their roots fix nitrogen to enrich the soil -- a very good thing considering what heavy feeders zucchini can be!
- Nasturtiums: Nasturtiums act as a trap crop for pests such as flea beetles and aphids, so if you commonly deal with these pests in your garden, you may want to plant an edging of nasturtiums around your summer squashes. The nasturtiums will distract the pests from attacking your summer squash plants.
