Do you like being surrounded by flowers and greenery, and feeling closer to nature? The biodiversity garden promotes the cultivation of native plants and the adoption of environmentally friendly culture methods. Your garden will attract a wide range of beneficial fauna.


For your biodiversity garden to be certified you must at least meet the three mandatory criteria listed below:

  1. Plant a variety of plants to prolong blooming, thus providing food for insects year round.
  2. Have at least one native species in your garden. To verify, consult VASCAN, the database of vascular plants of Canada, and make sure it is listed as a native plant in Québec or in your province.
  3. Maintain your garden an organic manner: be tolerant of insects and remove those that are unwanted manually or with a jet of water. Refrain from using any pesticides.

To improve and enrich your garden, you can also:

  • Choose plants with good disease, pests and drought resistance (they require fewer treatments).
  • Use compost and, if needed, natural fertilizers.
  • Use companion planting and crop rotation.

Certify your garden and promote organic gardening practices to your neighbours, colleagues and friends.

Tip sheet: Creating your biodiversity garden

Did you know that …

You need show tolerance and patience to attract biodiversity into your garden. Plants and animals don’t just move in overnight. Also, the presence of these new guests may not fit your notion of the ideal garden. The leaves of your plants are likely to be eaten by caterpillars – but you will eventually get to observe the butterflies. Bees and other pollinators will forage your flowers. Birds will dig into your flowerbeds for worms and insects. Don’t look at these intrusions negatively; rather, consider them a sign that you’ve done your work and your garden is becoming a space for life!
