Can You Plant Cabbage, Lavender, and Sunflowers Together?

Companion planting is a popular gardening technique that involves growing different plants together to enhance their growth, protect against pests, and improve soil health. In this article, we’ll explore whether cabbage, lavender, and sunflowers can be planted together successfully. You’ll learn about their compatibility, growing requirements, benefits, challenges, and best practices for planting.

Compatibility Analysis

Can you plant cabbage, lavender, and sunflowers together? The short answer is: Yes, with some considerations. While these plants can coexist, they have different needs that must be managed carefully.

• Cabbage: This cool-season vegetable thrives in well-drained, fertile soil and requires regular watering. It’s prone to pests like cabbage worms and aphids.
• Lavender: A drought-tolerant herb, lavender prefers well-drained, slightly alkaline soil and full sun. It acts as a natural pest repellent.
• Sunflowers: These tall, sun-loving plants require nutrient-rich soil and regular watering. They attract pollinators and can provide some shade.

The key factors to consider are their growth requirements, pest control benefits, nutrient needs, and spacing. While lavender can deter pests from cabbage, sunflowers can provide shade and attract beneficial insects.
