Questions concerning the environment? Contact the Green line!

A free telephone service is available from June to August to answer your questions about the environment, in particular about environmentally friendly lawn care, weeds, harmful plants, insects and animals, invasive exotic plant species, and alternatives to pesticides.

Environmentally friendly lawn

Learn about environmental practices to improve the health of your soil and lawn, such as managing weeds, grasscycling and household composting.
Harmful and invasive plants, and unwanted visitors

Ragweed, poison ivy, skunks and white grubs are not always welcome visitors. Contact us to come up with a strategy to keep them at bay.

Do you think you have an invasive exotic plant species in your garden and you don’t know how to get rid of it? We’d be happy to inspect the affected site and suggest solutions adapted to your yard.


Would you like to attract pollinators to your yard? It would be our pleasure to help you select the appropriate plant species.
