Companion planting is a popular strategy among gardeners seeking to maximize their harvests and promote plant health. But can kale, lemongrass, and nasturtiums thrive together in the same garden bed? In this article, we’ll explore their compatibility and provide practical tips for successful planting.

Compatibility Analysis

Yes, you can plant kale, lemongrass, and nasturtiums together, and here’s why. These plants complement each other well due to their differing growth requirements and natural pest-repellent properties. Kale, a leafy green, benefits from the pest-deterring properties of nasturtiums, while lemongrass can help repel common garden pests with its strong citrus scent. Additionally, nasturtiums attract beneficial insects like pollinators, enhancing the growth environment for all three plants.

Key Factors
