Can You Plant Cucumbers, Marigolds, and Nasturtiums Together?

Companion planting is a popular gardening technique that involves growing certain plants together to enhance growth, deter pests, and maximize space. If you’re considering planting cucumbers, marigolds, and nasturtiums together, you’re in for a treat. This article will explore their compatibility and provide insights into how to successfully cultivate these plants side by side.

Compatibility Analysis

Yes, you can plant cucumbers, marigolds, and nasturtiums together. These plants complement each other well due to their distinct yet harmonious characteristics. Cucumbers thrive with companions that help deter pests and improve soil health, which is where marigolds and nasturtiums come in.

Marigolds are excellent at repelling nematodes and other harmful insects, thanks to their pungent aroma. Nasturtiums, on the other hand, attract beneficial insects like pollinators and can act as a trap crop for aphids, drawing these pests away from cucumbers. All three plants share similar growth requirements, such as the need for full sun and well-drained soil, making them suitable companions in a vegetable garden.
