There are several methods that can be used to control weeds on a lawn in Calgary:
Proper maintenance: Maintaining a healthy lawn can make it more resistant to weed growth. This includes regular mowing, fertilization, and watering.
Hand-pulling: This is a manual method of removing weeds by hand. It is effective for small areas and for removing young, shallow-rooted weeds.
Herbicides: Chemical herbicides can be used to kill weeds in lawns. Selective herbicides target broadleaf plants (dicotyledon) without harming grass (monocotyledon) .It's important to choose an herbicide that is appropriate for the type of weeds you're trying to control and to follow the instructions on the product label. Always read the label for application methods, time of year and weather conditions for application and also for personal and environment safety measures.
Corn gluten meal: Corn gluten meal is a natural weed preventer that can be used as a pre-emergent herbicide. It works by preventing weed seeds from germinating.
Mowing: Mowing your lawn regularly at the appropriate height can help to prevent weed growth by shading out the weeds.
Aeration: Aerating your lawn can help to improve the health of the soil and promote better root growth, which can make your lawn more resistant to weed growth.
It's important to note that non-native invasive plants should be reported to Alberta Invasive Species Council to prevent them from spreading and damaging natural ecosystems
