How can I prevent weeds?
- Research plants you introduce to your garden
- Most weeds are referred to as escaped ornamental weeds
- Avoid bare ground in your yard, where weeds can easily germinate
- Stop weeds before they go to seed
- Beware of wildflower mixes that may contain weed seed
- Do not compost weed carcasses
- Share your knowledge with a neighbour
The City controls dandelions only when required based on threshold levels. Parks conducts regular preventative maintenance, as well as annual broadleaf weed inspections. If dandelions exceed established thresholds, an assessment is undertaken to determine what type of control is required.
Hand pulling is an excellent way to control small infestations. If you do choose to use a chemical, there are a number of products available from your local hardware store. If you are using a herbicide always read the label prior to any application, and ensure that you are using the product for its intended use.
Prohibited noxious weeds are highly invasive and must be completely removed. These plants pose an extreme risk to natural and agricultural areas. Inspection programs are in place to track their whereabouts throughout Alberta.
Noxious weeds easily establish and take over properties. These weeds must be controlled to stop their spread. Once established, they can prove difficult to remove.
Invasive plants are aggressive in nature and quickly out-compete native plants to reduce biodiversity. They can infest waterways, range lands, and change yards and natural habitats.
