Controlling Weeds & Lawn Insects
http://www.canadiantire.ca/AST/ResearchCentre/WeedLawnInsectsCare.jsp
There's nothing greener than having a healthy green lawn!
A beautiful lawn not only creates curb appeal for your home, it also provides many other benefits, including a cleaner environment. Grass is an ideal plant for urban settings and shouldn't be too difficult to maintain.
A healthy lawn:
Growing a thick, healthy lawn will help keep weeds out. Use mechanical and nutritional practices to grow a thick, green healthy lawn without pesticides. By following these simple steps, you can help reduce or avoid having to use weed and insect control products:
The Healthy Lawn Steps
STEP 1: Prepare - After a long winter, get your lawn ready for the summer.
What to do:
What to do:
Salt damage/pet damage: look for an all-in-one patch repair product with soil conditioner to reverse soil damage, as well as add grass seed and fertilizer in one step
Other bare patches: Use a 3-in-1 product with seed, mulch and fertilizer to quickly repair dead patches
Products you'll need:
What to do:
What to do:
What to do:
Over-seed the entire lawn for great results next spring and summer - this is the best time to apply grass seed. A fresh soil layer provides grass seed a rich base for germination
Use a fall fertilizer containing high potassium to prepare your lawn for cold winters. Nitrogen is stored in the plant over winter, which provides an early spring green-up
Products you'll need:
Broadleaf and Grass Weeds
Thick, healthy lawns are less susceptible to weed and insect problems. However, if your lawn is showing signs of weeds, you'll want to remove them immediately and repair it. Weeds are easier to control when they are small, before deep roots are established and seeds begin to form. Generally, it is easier to pull weeds when soil is wet, right after a rainfall or watering. If the problem persists, it is best to identify the weed or insect as well as the severity before further action is taken.
Prevention & Control
Beetles lay eggs in the soil in June, and young beetles (grubs) begin to grow and feed on grass plant roots in July/August. An infestation of grubs can cause damage in two ways: the grubs feed on roots, which causes the lawn to wilt, turn yellow and die out in patches, and foraging animals dig up the infested lawn to feed on the insects. Other lawn insects feed on blades of grass but have similar lifecycles to grubs, so the treatment timeframe is comparable.
Prevention & Control
Weed seeds will germinate in patios, sidewalks, fence lines and driveways. Removing weeds by hand from these areas can be difficult, especially once they're established. Larger perennial weeds often take root along fences where it is difficult to mow and trim. Weeds and grass will flourish in flower gardens that are well-fertilized and watered, and will take advantage of shady conditions under trees.
Prevention & Control
Integrated Pest Management is an environmentally sensitive approach to pest management. It employs a series of steps and techniques to effectively control and maintain pests at an acceptable level using tactics other than chemical or biological. It is an ecological approach that can significantly reduce or eliminate the use of pesticides; IPM emphasizes pest prevention, the use of reduced-risk products, and the application of pesticides only when necessary.
Basic Steps of IPM
If preventive and mechanical approaches to solving a pest problem have been unsuccessful, consider using a reduced-risk pest control product first. To learn more about reduced-risk products for lawn care, consult the most recent update on Reduced-Risk Pesticides in Canada. Follow directions carefully and always be sure to read and understand the label before applying any products

There's nothing greener than having a healthy green lawn!
A beautiful lawn not only creates curb appeal for your home, it also provides many other benefits, including a cleaner environment. Grass is an ideal plant for urban settings and shouldn't be too difficult to maintain.
A healthy lawn:
- Provides a safe, natural surface for children to play
- Increases property value and creates a serene haven
- Provides a dramatic cooling effect on the immediate area
- Oxygen producing grass is good for the environment as it removes carbon dioxide from the air
- Reduces run-off and water contamination by effectively absorbing rainfall better than weedy lawns or perennial gardens
- Significantly improves the quality of soil; in healthy lawns, grass plants produce miles of fibrous roots which when crowded together, forms a net system holding soil in place, reducing erosion
- As roots die off, the soil is enriched by humus formed by microorganisms
- Discourages noxious weeds as well as harmful insect and rodent infestations
Growing a thick, healthy lawn will help keep weeds out. Use mechanical and nutritional practices to grow a thick, green healthy lawn without pesticides. By following these simple steps, you can help reduce or avoid having to use weed and insect control products:
The Healthy Lawn Steps
STEP 1: Prepare - After a long winter, get your lawn ready for the summer.
What to do:
- Rake the lawn to remove debris and loosen the soil
- If the thatch layer is thick, use a manual or electric dethatcher instead of a garden rake
- Aerate lawn to encourage deep grass roots, help oxygen and nutrients get to the roots, and make it easier for water to soak into the soil
- Rake
- Dethatcher
- Aerator (or a spading fork)
- Garden waste bag
- Gloves
- Early spring, once the ground has dried and is firm to walk on
What to do:
Salt damage/pet damage: look for an all-in-one patch repair product with soil conditioner to reverse soil damage, as well as add grass seed and fertilizer in one step
Other bare patches: Use a 3-in-1 product with seed, mulch and fertilizer to quickly repair dead patches
Products you'll need:
- Lawn repair mix with soil conditioner
- 3-in-1 patch repair product
- Starter fertilizer
- Grass seed
- Lawn soil
- Early- to mid-Spring, when soil temperature reaches 15°C (60°F)
What to do:
- Over-seed the entire lawn each spring for a thicker, healthier lawn:
- Apply a 3-5 cm layer of lawn soil, then spread starter fertilizer and rake lightly, then apply grass seed and rake lightly again
- Apply a 3-in-1 lawn thickening mix in a spreader
- Keep the newly seeded lawn moist for the first few weeks to ensure that the seeds germinate
- Grass seed
- Fertilizer
- 3-in-1 lawn thickening mix (59-6360 CIL Golfgreen 3-in-1 Lawn Thickening Mix)
- Spreader
- Lawn soil
- Early to mid-spring for over-seeding and first fertilizer application
- Next fertilizer application should be 8 weeks later
What to do:
- Mowing: set mower to 3" (8 cm) or higher
- Water: use a sprinkler to apply enough water all at once to penetrate to roots. Once a week, early in the morning is all your lawn needs
- Remove weeds as they appear
- Fertilize every 2 months to keep the lawn thick, green and healthy
- Lawn mower
- Manual weeder
- Sprinkler
- Fertilizer
- Late spring and throughout the summer
What to do:
Over-seed the entire lawn for great results next spring and summer - this is the best time to apply grass seed. A fresh soil layer provides grass seed a rich base for germination
Use a fall fertilizer containing high potassium to prepare your lawn for cold winters. Nitrogen is stored in the plant over winter, which provides an early spring green-up
Products you'll need:
- Fall fertilizer
- Lawn soil
- Grass seed
- Leaf blower/vacuum
- Rake
- Garden waste bags
- Mid-August to mid-September for seeding
- Mid-September/October for fall fertilizer
Broadleaf and Grass Weeds
Thick, healthy lawns are less susceptible to weed and insect problems. However, if your lawn is showing signs of weeds, you'll want to remove them immediately and repair it. Weeds are easier to control when they are small, before deep roots are established and seeds begin to form. Generally, it is easier to pull weeds when soil is wet, right after a rainfall or watering. If the problem persists, it is best to identify the weed or insect as well as the severity before further action is taken.
Prevention & Control
- Use a weed prevention corn gluten product in early spring to prevent dandelion and crabgrass seeds from germinating
- Before resorting to weed or insect control products, try improving the general condition of your lawn by aerating, over-seeding and weeding by hand
- Use weeding tools to remove deep rooted weeds and prevent them from spreading
- Reseed affected area promptly to thicken turf naturally
- Fertilize your lawn every 2 months with a slow release nitrogen fertilizer
- Recurring pest problems are often a sign that lawn care practices need to change
- Examine your lawn care program and the lawn condition to see if anything needs to be done differently
- Improving your lawn care practices gives long-lasting results and reduces pest problems
- When weeds get out of control, spot-spray for 3 weeds per square meter
- Herbicides work best when weeds are actively growing and weather conditions are favourable (i.e.: temperature above 15 ºC and no rain forecasted for 12 to 24 hours)
- Reseed 4 to 6 weeks after treatment to thicken turf naturally
- Consult label for proper timing and application rates and procedures
- Follow directions carefully and always be sure to read and understand the label before applying any products

Other lawn insects feed on blades of grass but have similar lifecycles to grubs, so the treatment timeframe is comparable.
Prevention & Control
- A healthy, well-watered lawn is the best defense against lawn damage
- Treat the lawn when grubs are small and actively feeding (July/August)
- Use a Japanese Beetle Trap to lure and trap beetles, help reduce adult beetle population and control insect damage
- Repellents such as Critter Ridder may discourage animals from feeding on grubs in the lawn
- Follow directions carefully and always be sure to read and understand the label before applying any products
Weed seeds will germinate in patios, sidewalks, fence lines and driveways. Removing weeds by hand from these areas can be difficult, especially once they're established. Larger perennial weeds often take root along fences where it is difficult to mow and trim. Weeds and grass will flourish in flower gardens that are well-fertilized and watered, and will take advantage of shady conditions under trees.
Prevention & Control
- Remove small, isolated weeds by hand
- Use landscape fabric below garden mulch, decks and paths to stop weeds
- Use weeding tools to remove deep rooted weeds and prevent them from spreading
- Use Reduced Risk Products for spot-spray of isolated weeds and small areas when weeds are actively growing; this will prevent small weed problems from getting out of control
- Use non-selective weed control products to control tough grass and weed problems in large areas
- When spot-treating weeds in a flower or vegetable garden, shield desirable plants from drift with a piece of cardboard or plastic; if desirable plant is accidentally sprayed, rinse off immediately with water
- For best results, apply during warm, sunny weather (above 15 ºC) and read product label for any planting restrictions
- Use around sidewalks, patios and driveways, fence lines, and flower and vegetable gardens
- Follow directions carefully and always be sure to read and understand the label before applying any products
Integrated Pest Management is an environmentally sensitive approach to pest management. It employs a series of steps and techniques to effectively control and maintain pests at an acceptable level using tactics other than chemical or biological. It is an ecological approach that can significantly reduce or eliminate the use of pesticides; IPM emphasizes pest prevention, the use of reduced-risk products, and the application of pesticides only when necessary.
Basic Steps of IPM
- Establish and practice preventative measures in the lawn and garden
- Frequently monitor area(s) in order to identify pests before they become a severe problem
- Once identified as a problem, research the pest, its habitat, behaviour and reproductive cycle
- Determine the treatment needed (if any) to control the pest and maintain damage at an acceptable level
- Provide good soil with ample depth and organic matter for nutrition
- Choose the right mixture of grasses for the conditions
- Improve drainage in wet areas and/or replace lawns with other types of landscaping
- Check lawns and gardens regularly for first signs of insects, weeds and plant disease
- Remove diseased leaves, plants and branches to eliminate rotting organic matter
- Use screens on doors and windows and remove garbage to reduce pest problems in and around the home
If preventive and mechanical approaches to solving a pest problem have been unsuccessful, consider using a reduced-risk pest control product first. To learn more about reduced-risk products for lawn care, consult the most recent update on Reduced-Risk Pesticides in Canada. Follow directions carefully and always be sure to read and understand the label before applying any products
Use Pest Control Products when necessary
- Before resorting to using a pesticide, consider all your alternatives
- Use physical or mechanical methods like hand weeding, sticky traps, or light traps before resorting to chemical solutions
- To use IPM properly, you first need to correctly identify the pest and understand its life cycle
- Knowing when and how a pest is most susceptible to control measures is important when making decisions on when to take action
- Correct timing of a pesticide application is essential for effective control and to ensure the least amount necessary for control is used (refer to the label directions for guidance on the proper timing and recommended rate of application)
- Follow directions carefully and always be sure to read and understand the label before applying any products
