by

Spring is an exciting time for gardeners in Zone 4, as the last frosts begin to fade and the soil warms up. One of the most effective ways to enhance your garden’s productivity and health is through companion planting. This age-old technique involves planting certain crops together to benefit each other, whether by deterring pests, improving growth, or maximizing space.

What Is Companion Planting?

Companion planting is the strategic placement of plants to create a harmonious garden environment. It leverages natural plant relationships to reduce the need for chemical pest control and to boost crop yields. In Zone 4, where the growing season is shorter, choosing the right companions can make a significant difference in your garden’s success.

Benefits of Companion Planting in Zone 4

  • Pest control: Certain plants repel pests that threaten others.
  • Improved growth: Some combinations enhance nutrient uptake and growth rates.
  • Space efficiency: Companion planting maximizes limited growing space.
  • Soil health: Some plants fix nitrogen, enriching the soil naturally.
