Introduction

Courgettes (also known as zucchinis) are a popular vegetable in New Zealand gardens, thanks to their fast growth and versatility in cooking. By practicing companion planting, you can maximize courgette productivity, protect them from pests, and improve overall garden health.


What Is Companion Planting?

Companion planting is the practice of growing certain plants together to create a mutually beneficial relationship. This method can improve plant health, deter pests, attract pollinators, and optimize space in your garden.


Benefits of Courgette Companion Planting

  1. Pest Control:
    • Certain plants repel pests that commonly attack courgettes, such as aphids and squash bugs.
  2. Pollination Support:
    • Flowers from companion plants attract bees and other pollinators, boosting courgette production.
  3. Improved Soil Health:
    • Some companions fix nitrogen or improve soil structure, enhancing courgette growth.
  4. Efficient Space Use:
    • Companion plants make the most of limited garden space by growing vertically or filling gaps.

Best Companion Plants for Courgettes

  1. Marigolds:
    • Repel aphids, whiteflies, and nematodes while attracting pollinators.
  2. Nasturtiums:
    • Deter aphids and other pests; also edible and visually appealing.
  3. Beans:
    • Fix nitrogen in the soil, benefiting courgettes’ nutrient needs.
  4. Corn:
    • Acts as a windbreak and provides shade for courgettes during hot summers.
  5. Radishes:
    • Deter squash borers and can be harvested quickly to free up space.
  6. Basil:
    • Enhances flavor when grown nearby and repels harmful insects.
  7. Borage:
    • Attracts pollinators and improves overall plant health with its natural chemicals.

Plants to Avoid with Courgettes

  1. Potatoes:
    • Compete for nutrients and space, potentially stunting courgette growth.
  2. Pumpkins:
    • Both are heavy feeders and can overcrowd each other.
  3. Fennel:
    • Produces chemicals that can inhibit the growth of courgettes and other plants.
  4. Onions and Garlic:
    • May interfere with courgettes’ nutrient uptake.

Tips for Successful Companion Planting

  1. Plan Ahead:
    • Map out your garden to ensure compatible plants are grouped together.
  2. Rotate Crops:
    • Rotate courgettes and their companions annually to prevent soil depletion and pests.
  3. Maintain Balance:
    • Avoid overcrowding by giving each plant enough space to grow.
  4. Use Mulch:
    • Retain soil moisture and suppress weeds around courgettes and companions.
  5. Attract Pollinators:
    • Include flowering plants to draw bees and other pollinators to your garden.
