Can You Plant Cabbage, Potatoes, and Nasturtiums Together?

Companion planting is a popular practice among gardeners aiming to boost plant health, deter pests, and optimize garden space. Cabbage, potatoes, and nasturtiums often appear in discussions about companion planting. In this article, we’ll explore whether these plants can be successfully grown together and provide practical tips for doing so.

Compatibility Analysis

Yes, you can plant cabbage, potatoes, and nasturtiums together. This trio can make a harmonious combination in your garden, thanks to their complementary characteristics. Cabbage and potatoes are both cool-season crops that thrive in similar conditions, while nasturtiums act as a natural pest deterrent. However, it’s crucial to consider their growth requirements, pest control benefits, and spacing needs to ensure a successful planting.

Key Factors

• Growth Requirements: Both cabbage and potatoes prefer cooler temperatures and similar soil conditions. Nasturtiums can adapt to a variety of environments but thrive in full sun.

• Pest Control: Nasturtiums are known for repelling pests like aphids and whiteflies, which can benefit both cabbage and potatoes.

• Nutrient Needs: While cabbage and potatoes are heavy feeders, nasturtiums require fewer nutrients, reducing competition for resources.

• Spacing: Proper spacing is essential to allow each plant to access sunlight and air circulation, minimizing disease risk.
