Maintaining a weed and pest-free lawn is a key part of keeping your cool season grasses healthy and vibrant. While chemicals can be effective, it's important to use them judiciously and consider organic and mechanical methods as well. In this guide, we'll explore the proper thresholds for chemical use, risks, and benefits, along with DIY tips and Lawn Patrol's professional services.
Important note, following a good fertilizer and watering schedule along with proper mowing will create a healthy well kept lawn that is naturally resistant to weeds.
Proper Thresholds for Chemical Use:
One or two dandelions or an ant or two does not justify a full spray on your lawn. The chemicals available and used in Alberta are post emergent and systemic, meaning they need to be applied to a living plants foliage to be effective. So having a contractor apply your full yard when you have no weeds doesnt prevent them.
A common threshold for full application would be 1 weed every 10 square feet or so.
Consider spot spray treatments when available
Selective Herbicides: Use selective herbicides that target specific weeds without harming your grass. Apply according to label instructions and only when weeds reach a certain threshold.
Integrated Pest Management (IPM): IPM involves using a combination of strategies, including cultural, biological, and chemical control methods, to manage pests effectively while minimizing environmental impact.
Risks and Benefits of Chemicals:
Risks: Overuse of chemicals can lead to environmental damage, harm to beneficial insects, and resistance in target pests. Improper application can also pose risks to human and animal health.
Benefits: When used correctly, chemicals can effectively control weeds and pests, leading to a healthier lawn.
DIY Tips and Tricks:
Organic Methods: Use organic weed control methods such as hand-pulling, mulching, and using natural herbicides like vinegar or boiling water.
