Zucchini Companion Plants

If you’re thinking of growing zucchini and you wanted to incorporate companion planting in your garden, you should have a list of zucchini companion plants. These plants will not only help the zucchini to grow but will also protect it from pests and diseases, while also improving the nutrients of the soil. On the other hand, the zucchini can also help these plants to grow better.

If you take good care of the plants and provide them with the nutrients they need, one plant alone could yield tons of zucchinis. One way to help make your zucchini plants to grow faster is by applying companion planting.

What is Companion Planting?

Companion planting is a gardening method that requires planting different types of crops in close proximity to each other. This method of planting provides plenty of benefits to the crops. Aside from enriching the soil, the companion plants for zucchini can help to drive away harmful pests while attracting beneficial pests. In fact, the main reason why farmers and gardeners would apply companion planting is to deter pests. When done correctly, companion planting can help stimulate the growth of your zucchini plants.

As mentioned, there are many benefits that come with companion planting. Here are some of them:

1. Repel Harmful Pests

One of the biggest challenges you will have to face as a gardener is the infestation of harmful insects and pests, such as beetles, worms, flies, and moths. Companion planting may be the best solution to this. That’s because certain plants are capable of driving away these pests. So if you grow them near your zucchini plants, they will help to protect your zucchinis from these pesky pests.

Here is the list of the best pest repelling plants for your garden.

2. Attract Beneficial Insects

Not all insects are bad for your garden. Pollinators like ladybugs and bees can help to stimulate the growth of your plants. Some gardeners would use companion planting to encourage these insects to visit the garden and encourage pollination.

3. Improve the Nutrients of the Soil

When your zucchini crops will start to grow, they will take up lots of valuable nutrients from the soil. If this happens, you will have to work really hard to revitalize your soil’s nutrients. But if you apply companion planting, some of these plants can help to put nutrients back into the soil such as nitrogen. As a result, your plants will grow healthy and well-fed.

4. Stimulate Growth

Some of the plants to grow with zucchini could release certain chemicals that could stimulate the growth of your zucchini plants. These chemicals will not only stimulate their growth but will also help your plants to produce better tasting yields.
