Ortho WeedClear Weed Killer for Lawns Concentrate - Kills Dandelion

In this review of Ortho WeedClear Weed Killer for Lawns Concentrate the bottom line is clear: this concentrate is for homeowners who want a single-application solution to kill broadleaf weeds such as dandelion and clover without harming established turf when used as directed. The product treats a large area from one container and becomes rainproof in one hour, making timing and weather less of a worry. While performance varies by weed and application method, the concentrate format and compatibility with common sprayers make it a practical choice for routine lawn maintenance.

Key Features

• Kills over 250 weeds: The formula is labeled to control more than 250 listed broadleaf weeds, so it covers common lawn invaders like dandelion and clover.
• Concentrated formula: The concentrate mixes with water, allowing one 1 gal container to treat up to 64,000 sq. ft., which is economical for larger yards.
• Fast acting and rainproof: Results can appear within hours after one application and the treatment becomes rainproof in about 1 hour, reducing reapplication risk from sudden showers.
• Compatible with multiple sprayers: It can be applied using a tank sprayer or an Ortho Dial N Spray hose-end sprayer for flexible application options.
• Safe for many turf types: When used as directed it is formulated to kill weeds without harming common turfgrasses like Kentucky Bluegrass, Bermudagrass, and St. Augustinegrass (not Floratam).

Who It's For

This product is best for homeowners with established lawns who need a broad-spectrum broadleaf weed control option that can cover large areas from one container. It suits people who already own or plan to use a tank sprayer or hose-end sprayer and who can apply when weeds are actively growing and daytime temperatures are below 90F.

Those who should look elsewhere include gardeners with delicate or unlisted turf varieties, people unwilling to mix concentrate products, or anyone expecting guaranteed, uniform results on every weed regardless of application technique. Some customers report inconsistent weed mortality, so professional lawn services or spot treatments with alternate chemistries may be better for stubborn infestations.
