Lawn & Property Care
Fertilization & Weed Control
Feed it right, time it right, and the weeds lose. A seasonal program that builds thick, green turf the way Ontario's rules allow.
Ontario bans the cosmetic use of most pesticides on lawns, so the old spray-and-forget approach is gone. What works now is a program: the right fertilizer at the right time, lower-risk weed control from the province's allowable list, and turf thick enough that weeds can't get started. Groundwork Landscaping plans each visit around your lawn, the season and the weather.
What's included
- Spring feeding to green up the lawn and help it recover from winter.
- Early summer feeding with slow-release nitrogen that won't burn in the heat.
- Fall feeding, the most important visit, to build roots before winter.
- Weed control with products allowed for cosmetic use in Ontario, spot-treated where weeds are.
- Grub checks, with beneficial nematodes or other allowed treatments when grubs are found.
- A note after every visit about what was applied and anything you should do, like watering it in.
How a program works
- Assess the lawn. We look at grass type, thin areas, weeds, soil and sun.
- Plan the visits. Usually four or five visits from spring to late fall.
- Apply and post. Products applied at label rates, with any notice signs the province requires.
- Adjust. We change the plan if the lawn needs more seed, more water or less nitrogen.
Be realistic about weeds
Allowed products work more slowly than the old sprays, and dense weeds may take a season or two. The fastest results come from pairing feeding with aeration and overseeding and proper mowing height. Badly damaged lawns may be better off with new sod.
What affects the cost of fertilization & weed control
Programs are priced on the size of the lawn and the number of visits in the season. Heavy weed pressure, grub treatment, extra spot treatments and add-ons like aeration or overseeding change the total. Most companies price the full season up front, so you know the cost of every visit before the first one.
Fertilization & Weed Control questions
Can you still kill weeds in Ontario?
Yes, with products whose active ingredients are on Ontario's allowable list, such as iron-based weed control. They work more slowly, so thick turf does most of the long-term work.
Is it safe for kids and pets?
We use products allowed for cosmetic use in Ontario and follow the label. We'll tell you if anyone should stay off the lawn for a while after a visit.
Why is the fall application so important?
In the fall, grass puts its energy into roots. Feeding then builds a stronger lawn for spring and helps it survive winter.
What are grubs, and do I have them?
Grubs are beetle larvae that eat grass roots. If patches lift like loose carpet or skunks and raccoons dig your lawn, grubs are likely. We check and treat when needed.
Do I need to water after a treatment?
Some visits need watering in, others need a dry day. We'll leave a note after each visit telling you which.
How long until I see results?
Most lawns green up within a couple of weeks of the spring feeding. Weed control is gradual, and a lawn full of weeds usually takes a full season, plus overseeding, to turn around.
Will fertilizer burn my lawn?
Not when it's applied at the right rate and time. We use slow-release products in summer heat and skip or delay a visit during drought.
