Can You Plant Kale, Rosemary, and Nasturtiums Together?

Companion planting is a time-honored gardening technique that involves growing different plants together to enhance growth, deter pests, and maximize garden space. Gardeners often wonder about the compatibility of kale, rosemary, and nasturtiums. In this article, you’ll learn whether these plants can thrive together and how to make the most of your vegetable and herb garden.

Compatibility Analysis

Yes, you can plant kale, rosemary, and nasturtiums together, but with some considerations. These plants complement each other in various ways, though they have different growth requirements. Here’s why they can work well together:

• Growth Requirements: Kale prefers cooler temperatures and partial shade, while rosemary thrives in full sun and warmer conditions. Nasturtiums are adaptable and can handle both conditions, making them a versatile companion.
• Pest Control: Nasturtiums are known for their pest-repelling properties, particularly against aphids, which can plague kale. Rosemary also deters certain pests, such as cabbage moths, with its strong aroma.
• Nutrient Needs and Spacing: Kale and nasturtiums have moderate nutrient needs, while rosemary requires well-drained soil with less frequent feeding. Proper spacing ensures each plant receives adequate resources without competition.
