Ragweed is a widespread weed in Qu\u00e9bec. It is present from May to October and dies at the first frost in the fall. In mid-July, ragweed begins to bloom and produce pollen. The pollen travels through air in a fine dust and causes allergic reactions in people who are sensitive to it. It affects over a million people in Qu\u00e9bec between July and October. Known as hay fever, symptoms include sneezing, nasal congestion, watery eyes, chronic sinusitis and even asthma. We can all do our part to reduce the spread and noxious effects of this invasive plant.<\/p>\n
Ragweed grows well in poor soil, which is why it is often found along streets and sidewalks or growing out of cracks in the pavement. Our best strategy against the spread of this plant is to uproot it or cut it off at ground level. Mowing also helps by preventing or delaying the flowering stage. Ragweed can grow up to 2 metres in height and can be recognized by its serrated leaves and spiked flowers.<\/p>\n
