Can You Plant Lettuce, Nasturtiums, and Calendula Together?

Companion planting is a time-tested gardening technique where certain plants are grown together to mutually benefit one another. Many gardeners wonder if lettuce, nasturtiums, and calendula can be planted together. In this article, we’ll explore their compatibility, benefits, and any challenges you might face. By the end, you’ll have a clear understanding of how to successfully grow these plants side by side.

Compatibility Analysis

Yes, you can plant lettuce, nasturtiums, and calendula together. These plants complement each other well, creating a harmonious garden environment. Let’s delve into why they work together:

• Growth Requirements: Lettuce prefers cooler temperatures and partial shade, which nasturtiums can provide with their sprawling nature. Calendula, with its bright flowers, is adaptable and can thrive in similar conditions as lettuce.

• Pest Control: Nasturtiums act as a trap crop for aphids, drawing them away from lettuce. Calendula attracts beneficial insects like ladybugs, which help control aphid populations.

• Nutrient Needs: All three plants have moderate nutrient requirements and don’t heavily compete for resources, making them suitable companions.

• Spacing: Nasturtiums can spread out, providing ground cover, while lettuce and calendula can be interspersed without overcrowding.
