Companion Planting Guide: Enhancing Your Garden’s Health and Productivity with GuanoBoost

Gardening enthusiasts welcome to the world of companion planting! Here at GuanoBoost, we are dedicated to promoting organic gardening practices that enhance the health and productivity of your garden. Today, we’ll explore the benefits of companion planting and provide a comprehensive guide to get you started on this journey.

What is Companion Planting?

Companion planting is an age-old gardening technique where different plants are grown in proximity to each other to mutually benefit from their unique properties. This method leverages the natural relationships between plants to improve growth, deter pests and enhance soil fertility.

Benefits of Companion Planting

  1. Pest Control: Certain plants can repel pests that might otherwise damage neighbouring crops. For example, marigolds are known to deter nematodes, while basil can repel flies and mosquitoes.
  2. Improved Soil Health: Some plants, like legumes, can fix nitrogen in the soil, enriching it for other crops. This natural fertilisation process reduces the need for chemical fertilisers.
  3. Enhanced Growth: Companion plants can improve each other’s growth rates by providing shade, support or nutrients. For instance, the classic “Three Sisters” trio of maize, beans and squash showcases how these plants support one another: maize offers a structure for beans to climb, beans fix nitrogen in the soil and squash spreads along the ground, suppressing weeds.
  4. Increased Biodiversity: A diverse garden is a resilient garden. By planting a variety of species, you can create a balanced ecosystem that supports beneficial insects and other wildlife.
  5. Optimised Space: Companion planting allows for more efficient use of garden space, making it ideal for both small and large gardens.

Getting Started with Companion Planting

  1. Plan Your Garden Layout: Begin by sketching a rough layout of your garden. Identify the main crops you want to grow and research their compatible companions.
  2. Choose Your Companions: Here are some popular companion pairs:
    • Tomatoes and Basil: Basil enhances the flavour of tomatoes and deters pests like aphids.
    • Carrots and Onions: Onions repel carrot flies and carrots help to aerate the soil for onions.
    • Cabbage and Dill: Dill attracts beneficial insects that prey on cabbage pests.
    • Radishes and Spinach: Radishes can help to loosen the soil for spinach roots.


  1. Consider Planting Density: Ensure that your companion plants have enough space to thrive. Overcrowding can lead to competition for resources and increase the risk of disease.
  2. Rotate Crops: Practise crop rotation to maintain soil health. Avoid planting the same family of crops in the same spot each year to prevent the buildup of pests and diseases.
  3. Use Organic Fertilisers: Enhance the benefits of companion planting by using organic fertilisers like GuanoBoost. Our fertilisers provide essential nutrients that support plant growth and soil health without the harmful chemicals found in synthetic alternatives.

Tips for Successful Companion Planting

  • Observe and Adjust: Pay attention to how your plants interact and be ready to make adjustments. Gardening is an ongoing learning process.
  • Incorporate Flowers: Flowers such as marigolds, nasturtiums and calendula not only add beauty to your garden but also attract pollinators and beneficial insects.
  • Utilise Vertical Space: Use trellises and supports to grow climbing plants, maximising your garden space.
  • Maintain Soil Health: Regularly add organic matter, such as compost or well-rotted manure, to keep your soil rich and healthy.



Companion planting is a powerful tool for any gardener looking to boost the health and productivity of their garden naturally. By carefully selecting and pairing plants, you can create a thriving, sustainable garden ecosystem.
