Companion planting has long intrigued gardeners looking to maximize their garden’s health and productivity. Combining radishes, potatoes, and calendula might seem unconventional, but this trio can offer surprising benefits. In this article, you’ll discover if these plants can thrive together and learn practical tips to make your garden flourish.

Compatibility Analysis

Yes, you can plant radishes, potatoes, and calendula together, although there are some considerations to keep in mind. These plants complement each other in several ways. Radishes grow quickly and can be harvested before potatoes spread out, while calendula acts as a natural pest deterrent. However, each has unique growth requirements that need to be balanced.

Key Factors
