How to Control Crabgrass in Ontario
Crabgrass is a common weed that can be frustrating to deal with in lawns and gardens. In Ontario, where the climate and soil conditions are well-suited for its growth, controlling crabgrass becomes even more important. This article will provide you with valuable information and effective strategies to help you control crabgrass and maintain a healthy, weed-free lawn in Ontario.
Understanding Crabgrass
Before diving into the methods of controlling crabgrass, it’s essential to understand the characteristics of this weed. Crabgrass (Digitaria spp.) is an annual grassy weed that spreads through its abundant seeds. It typically germinates in spring and thrives during the warm summer months. Here are a few key features of crabgrass:
- Crabgrass has a prostrate growth habit, meaning it spreads horizontally along the ground.
- The leaves of crabgrass are light green in color and have a coarse texture.
- Crabgrass produces extensive root systems, enabling it to survive even under adverse conditions.
- It can quickly take over lawns, garden beds, and bare patches of soil if left unchecked.
Prevention Techniques
The best way to control crabgrass is through preventive measures. By taking proactive steps to create unfavorable conditions for crabgrass growth, you can significantly reduce its presence. Here are some effective prevention techniques:
1. Proper Lawn Maintenance
Maintaining a healthy lawn is the first line of defense against crabgrass invasion. Follow these tips for proper lawn care:
- Mow your lawn at the appropriate height for your grass type, as recommended by experts. This helps shade the soil and restrict crabgrass growth.
- Water deeply but infrequently, ensuring your lawn receives about 1 inch of water per week. This promotes deep root growth of desired grass and discourages crabgrass.
- Aerate your lawn to improve soil drainage and reduce compaction, which can create favorable conditions for crabgrass.
2. Overseeding
Overseeding involves planting grass seed over an existing lawn to fill in bare spots. A thick, healthy lawn can outcompete crabgrass and other weeds. Here’s how to overseed effectively:
- Choose a quality grass seed blend suitable for your region and lawn conditions.
- Mow your existing lawn shorter than usual to expose the soil surface for better seed-to-soil contact.
- Spread the grass seed evenly across the lawn, following the recommended seeding rate provided by the seed manufacturer.
- Rake the seed lightly into the soil and water thoroughly.
- Keep the newly seeded area moist until the grass establishes.
3. Weed Control Products
Using pre-emergent herbicides is an effective way to prevent crabgrass germination. These herbicides create a barrier on the soil surface, inhibiting the growth of crabgrass seeds. Follow these guidelines when using weed control products:
- Apply pre-emergent herbicides in early spring, before crabgrass seeds start to germinate. Timing is crucial, so check local weather and soil temperature conditions.
- Read and follow the instructions provided by the herbicide manufacturer carefully.
- Water the treated area lightly after application to activate the herbicide.
- Be cautious when using herbicides near ornamental plants or desirable grasses. Selective herbicides are available for specific types of grasses, so choose the appropriate product.
Post-Emergent Control Methods
If crabgrass has already emerged in your lawn, it’s necessary to employ post-emergent control methods to eliminate the existing weeds. Here are a few effective options:
1. Hand Pulling
For small infestations, hand pulling can be an effective way to remove crabgrass. Ensure you remove the entire plant, including the roots, to prevent regrowth. It’s easier to pull crabgrass when the soil is moist.
2. Spot Treatment with Herbicides
Herbicides designed specifically for broadleaf weeds can be used to spot treat crabgrass. Apply the herbicide directly to the weed, following the product instructions and safety guidelines. Take care not to spray desired plants or grasses.
3. Lawn Renovation
In severe cases of crabgrass infestation, lawn renovation might be necessary. This involves starting from scratch by killing the entire lawn, removing the dead grass, and reestablishing a new, weed-free lawn. Consult a lawn care professional for guidance on the best approach for your specific situation.
Crabgrass can be a persistent weed in Ontario, but with proper preventive measures and control strategies, you can successfully manage its growth and keep your lawn looking lush and healthy. Remember to follow a regular lawn maintenance routine, overseed to promote a thick lawn, and use weed control products when necessary. By implementing these techniques, you’ll be well on your way to controlling crabgrass and enjoying a beautiful lawn all season long.

Frequently Asked Questions
What is crabgrass and why is it a problem in Ontario?
Crabgrass is a common annual weed that thrives in warm-season grasses and is considered a nuisance in Ontario. It grows rapidly, spreads quickly, and competes with desirable grass species, resulting in an unsightly and unhealthy lawn.
When is the best time to control crabgrass in Ontario?
The ideal time to control crabgrass in Ontario is in the spring before it germinates. Pre-emergent herbicides should be applied when soil temperatures reach around 12 degrees Celsius. This usually occurs in late April or early May, depending on the weather.
What are the most effective methods to control crabgrass in Ontario?
There are several effective methods to control crabgrass in Ontario:
- Maintain a healthy, thick lawn by proper watering, mowing, and fertilization to discourage crabgrass growth.
- Apply pre-emergent herbicides in the spring to prevent crabgrass seeds from germinating.
- Post-emergent herbicides can be used to control existing crabgrass plants. Make sure to follow the instructions carefully.
- Regularly remove any crabgrass plants manually or by using a weeding tool.
Can I prevent crabgrass without using chemicals?
Absolutely! While herbicides are effective, there are non-chemical methods to prevent crabgrass. Maintaining a healthy lawn by regularly mowing at the correct height, watering deeply but infrequently, and applying proper fertilization can help prevent crabgrass infestation. Additionally, overseeding your lawn with desirable grass species can help fill in any bare spots, making it more difficult for crabgrass to establish.
How can I avoid spreading crabgrass seeds in my lawn?
To avoid spreading crabgrass seeds in your lawn, be cautious when mowing areas with mature crabgrass plants. Mow these areas separately and clean the mower thoroughly afterward to prevent seed dispersal. Additionally, ensure that any tools used for removing crabgrass are cleaned or disinfected to prevent unintentional spreading.
What should I do if my lawn is already infested with crabgrass?
If your lawn is already infested with crabgrass, it’s important to take action promptly. Apply a post-emergent herbicide specifically designed to target crabgrass. Follow the product instructions carefully and consider seeking professional help for severe infestations. Additionally, continue practicing good lawn maintenance habits to prevent future infestations.
Final Thoughts
In conclusion, controlling crabgrass in Ontario requires a combination of preventive measures and targeted treatments. Regularly mowing your lawn at the correct height and applying a pre-emergent herbicide in early spring can help prevent crabgrass from taking hold. For existing infestations, spot-treating with a post-emergent herbicide can effectively eliminate the weeds. Additionally, maintaining a healthy and dense turf through proper watering, fertilizing, and aerating can help prevent crabgrass from establishing itself.
