Why do I need Companion Plants to grow Zucchinis?

While you don’t necessarily need to grow zucchinis together with other plants, it is still advisable since you can use your space more efficiently and also benefit from the positive effects good companion plants can have on the growth behavior and on the yields of your zucchinis.
