Can You Plant Eggplant, Marigolds, and Nasturtiums Together?

Companion planting is a time-honored gardening technique where certain plants are grown together to enhance growth, deter pests, and improve yields. Eggplant, marigolds, and nasturtiums are popular choices in many gardens, but can they thrive together? In this article, we’ll explore their compatibility, benefits, challenges, and best practices for a successful companion planting experience.

Compatibility Analysis
