Best Zucchini Companion Plants

1. Borage

Borage is a flowering herb that has a dual effect as a zucchini companion plant in the garden. Firstly, it attracts beneficial pollinators like honeybees for zucchini flowers, and secondly, it deters voracious insects.

2. Beans

Beans are advantageous for zucchini fruit production, as they emit nitrogen back into the soil, which feeds neighboring zucchini. They also help in repelling garden beetles and other pests that might harm zucchini vines.

3. Radishes

Radishes are an ideal companion plant for zucchini as they repel squash vine borers and beetles. If not prevented early, these harmful pests can damage the crops quickly.

4. Garlic

Garlic helps in preventing destructive aphids from the garden, which can cause massive damage to zucchini and its leaves.

5. Spinach

Spinach and zucchini reciprocally useful to each other if planted together. Zucchini gets benefits from the nutrients that spinach releases back to the soil. In return, zucchini provides shade and protection to spinach plants during hot months of summer.

6. Corn

Corns are also useful companion plants for zucchini, as they help in keeping away damaging vine borers out of the garden.

7. Peas

Just like beans, peas also release beneficial nitrogen back to the soil, which aids in the growth of heavy-feeder zucchini plants. This exchange works on the neutralization of soil depletion.

8. Nasturtiums and Marigolds

Colorful nasturtium plants can brighten up any garden and also attract beneficial pollinators. As Nasturtiums attract aphids, you can smartly use these beautiful flowers as a host and protect the neighboring plants that are affected by aphids.

9. Herbs

Herbs like peppermint, oregano, catnip, marjoram, parsley, mint, dill, and lemon balm are useful companion plants with zucchini. These herbs help in keeping pests away from zucchini plants.


Plants to Avoid with Zucchini

While some plants are a great companion to zucchini plants, and on the other hand, a few are not good for them. 

1. Pumpkin

Pumpkins and squash belong to the same family; hence they can cross-pollinate with each other, and that results in poor production of fruits.

2. Potatoes

Avoid planting potatoes along with zucchini as both plants suffer from the same garden pests, and growing them together can make them more susceptible to infestation. Apart from that, potatoes are heavy-feeders that can consume large amounts of nutrients from the soil.
