Broadleaf Weed Control in Ontario Lawn

An Ontario homeowner had broadleaf weeds (clover, dandelion, thistle) in a neglected corner lot and asked for chemical control.

Herbicide Selection

• Look for 2,4-D, MCPP, Dicamba or combos (broadleaf weed killers).
• Check local nursery for available products.
• Safe on fescue/bluegrass at label rates.

Application Timing

• Temp 40–85°F.
• Weeds young & actively growing = easiest kill.
• Mow, wait 4–5 days for regrowth, spray with 48h rain-free window.

Precautions

• Avoid root zones of desirable trees/shrubs.
• Spot-spray under trees; don't broadcast near them.
• Read/follow label.

Standard broadleaf herbicide + proper timing = clean lawn.
