Ragweed season is at its peak in July, triggering health problems for many Québecers. Here are some tips to keep this troublesome plant off your property.
1. Where ragweed is found
Ragweed mostly grows in poor soil. It is mainly found in the following areas:
- Along streets and sidewalks
- On the side of paved roads
- On vacant lots
- On lands under construction
- On industrial lands
- On lands that serve as snow dumps
2. Identifying and distinguishing ragweed
The appearance and size of this weed vary according to its stages of growth, but it can reach up to 2 metres in height. You can recognize ragweed by its ragged and spine-like leaves, which are similar to those of carrots and by its hairy stem.
Ragweed is often confused with poison ivy. The appearance of these two plants is very different and they do not have the same impacts on health. Touching ragweed presents no risk, whereas touching poison ivy is dangerous.
3. Pulling or mowing ragweed
The best way to reduce the impact of ragweed is by eliminating it from your surroundings. On small land, such as a residential one, it is best to pull the ragweed as soon as you spot it. For larger land, you can cut the plant with a lawnmower.
4. Preventing ragweed from growing
Ragweed does not grow easily on healthy and fertile lawns. To limit the presence of ragweed, you can do the following:
- Use mulch or groundcover in places where there is no lawn
- Improve soil quality with compost or fertilizer
- Sow the land, or plant other vegetation
