Moreover, both plants have similar sunlight and soil requirements, making them suitable companions.

Key factors in their compatibility include:

• Growth Requirements: Both plants thrive in full sun and well-drained soil.
• Pest Control: Nasturtiums act as a trap crop, attracting aphids away from potatoes.
• Nutrient Needs: Neither plant has particularly high nutrient demands, reducing competition.
• Spacing: Proper spacing ensures both plants have enough room to grow without competing for resources.
