Ragweed is a weed that can be found from May to October. It starts to flower in mid-July, releasing fine dust-like pollen into the air. This dust causes allergic reactions in sensitive individuals.
Ragweed pollen is the main cause of the seasonal rhinitis that affects one out of every seven Quebecers.
Minimizing the effects of ragweed
The best way to minimize the adverse effects of ragweed is to limit the quantity in the surrounding environment.
Pulling up or mowing ragweed
- Pull out or mow any ragweed on your property before it releases its pollen (mid-July and mid-August).
- Use your hands or a garden weeder to pull it up.
- Throw out any pulled-up plants or cuttings with your garbage.
- Prevent ragweed from growing back.
- Use mulch or ground-cover plants in areas where there is no grass.
- Improve the quality of your soil with humus, compost or fertilizer.
- Sew grass or clover after pulling out ragweed.
- Inspect your property regularly.
- Keep your lawn dense and healthy to prevent ragweed seeds from germinating.
Even though Pincourt doesn’t have any by-laws on ragweed at this time, a major awareness campaign is conducted every summer by Green Line personnel. Among other things, they conduct foot patrols to look for ragweed. Whenever they spot ragweed, they leave an informative door hanger sign at the address in question.
The town’s inspector-technician can also leave notices at homes where ragweed has been found.
