Can You Plant Kale, Nasturtiums, and Alyssum Together?

Companion planting is a popular strategy among gardeners aiming for a thriving garden ecosystem. By pairing plants with complementary characteristics, gardeners can enhance growth, deter pests, and maximize space. In this article, we explore whether kale, nasturtiums, and alyssum are compatible companions and offer practical tips for planting them together.

Compatibility Analysis

Kale, a nutrient-loving leafy green, benefits from the pest-repelling properties of nasturtiums, while alyssum attracts beneficial pollinators. Key factors contributing to their compatibility include similar growth requirements, pest control benefits, and efficient use of garden space.

Growth Requirements
