Can You Plant Cabbage, Sweet Potatoes, and Lavender Together?

Companion planting is a popular gardening technique that involves growing different plants in proximity to benefit each other. While cabbage, sweet potatoes, and lavender are all beloved by gardeners, can they thrive together? This article explores their compatibility, offering insights into their growth requirements, potential benefits, and challenges, along with practical planting tips.

Compatibility Analysis

Can you plant cabbage, sweet potatoes, and lavender together? The short answer is NO. These plants have differing growth requirements and preferences that make them incompatible as companions.

• Cabbage prefers cooler temperatures, consistent moisture, and rich, well-drained soil. It is part of the Brassica family, which is often susceptible to pests like cabbage worms and aphids.

• Sweet Potatoes thrive in warm, sunny conditions and require sandy, well-drained soil. They are vining plants that need space to spread out.

• Lavender is a hardy herb that prefers dry, well-drained soil and full sun. It is drought-tolerant and thrives in conditions that would not suit cabbage.

These differing needs in terms of temperature, moisture, and soil type mean they are unlikely to thrive when planted together.

Benefits of Planting Together

While cabbage, sweet potatoes, and lavender may not be ideal companions, each brings unique benefits to the garden when paired with other suitable plants:

• Pest Repellent Properties: Lavender can repel pests like moths and beetles, making it a great companion for other plants that are prone to these pests.
