TLDR Review: Ortho WeedClear Weed Killer
Verdict
The Ortho WeedClear Weed Killer is a solid choice if you're after an effective, lawn-safe solution for dandelions and clover, especially on St. Augustine grass. While it takes a few days to see full results and requires some patience, its coverage capability and lawn safety make it worth considering. However, be aware of potential spray mechanism issues and the need for multiple applications. If you want a more immediate or user-friendly spray experience, you might consider other brands with better sprayer designs or faster-acting formulas.
