  • Nasturtium companion planting provides numerous benefits, including pest control, nutrient sharing, and vibrant colors that enhance the garden’s visual appeal.
  • As natural pest repellents, nasturtiums reduce the prevalence of aphids, whiteflies, and squash bugs. This makes them an effective form of pest control.
  • Additionally, their deep-rooting system brings nutrients from deeper soil levels, which benefits shallower-rooted plants nearby.
  • The bright flowers of nasturtiums add a pop of color to the garden, creating a visually appealing and vibrant atmosphere.
