Companion planting is a gardening technique that involves growing different plants together to enhance growth, deter pests, and maximize space. In this article, we’ll explore whether peppers, lavender, and fennel can be planted together, examining their compatibility and offering practical tips for success.

Compatibility Analysis

Can you plant peppers, lavender, and fennel together? The short answer is NO. While peppers and lavender can thrive together due to similar sunlight and water needs, fennel is generally not a good companion for most plants, including peppers and lavender.

Why They May Not Work Together

• Growth Requirements: Peppers and lavender both prefer full sun and well-drained soil, while fennel can be more aggressive in its nutrient uptake, potentially outcompeting its neighbors.

• Nutrient Needs: Fennel exudes a chemical that can inhibit the growth of nearby plants, making it a poor companion for peppers and lavender.
• Spacing: Peppers and lavender can be spaced closely, but fennel requires more room due to its larger growth habit.
