Can You Plant Cabbage, Fennel, and Lemongrass Together?

Companion planting is a popular technique among gardeners looking to optimize their garden’s productivity and health. When considering whether to plant cabbage, fennel, and lemongrass together, it’s essential to understand their compatibility. This article will delve into the compatibility of these plants, their growing requirements, and the benefits and challenges of growing them together.

Compatibility Analysis

The short answer to whether cabbage, fennel, and lemongrass can be planted together is NO. These plants have different growth requirements and can negatively impact each other’s development.

• Cabbage prefers cooler temperatures and can be susceptible to pests like cabbage worms. It requires consistent moisture and benefits from companions that deter pests.
• Fennel is known for inhibiting the growth of many plants, including cabbage, due to its allelopathic properties. It releases compounds that can stunt the growth of nearby plants.
