Companion planting is a popular gardening technique where certain plants are grown together to enhance growth, deter pests, or improve flavor. This article explores whether beans, lavender, and marigolds can coexist harmoniously in your garden and offers practical tips for success.

Compatibility Analysis

Yes, you can plant beans, lavender, and marigolds together, but with some considerations. Each plant has unique growth requirements, yet they share certain characteristics that make them compatible companions.
