Gordon's Trimec Lawn Weed Killer review
A selective lawn herbicide formulated to kill a broad range of common lawn weeds without harming the grass.
Quick take
Trimec is a longstanding lawn herbicide brand family, but it comes in more than one formulation — including a standard version and a Crabgrass Plus version aimed specifically at crabgrass. This listing is a 32 fl oz liquid spray using Trimec as the active herbicide, but detailed marketing copy on the current listing doesn't specify which exact Trimec variant this is. Confirm the specific product name against Gordon's current lineup before assuming it matches every weed claimed under the broader Trimec family.
From a trusted source
A friend recommended Gordon's weed killer, and I tried it in July. It worked exceptionally well on the crabgrass in my yard, so I plan to use it again. Note: I haven't confirmed whether the exact bottle I used was this standard formula or the Crabgrass Plus variant, so treat the crabgrass result as a Trimec-family result rather than proof for this specific product.

Who it's for
Good fit
- Homeowners dealing with common broadleaf lawn weeds like dandelion
- Anyone wanting a selective herbicide that targets weeds, not grass
- People treating a lawn during the active growing season — confirm crabgrass-specific control needs the right Trimec variant
Skip it if
- You have a lawn with grass types sensitive to Trimec — always check the label for your specific grass type
How it's used
As a selective herbicide, Trimec is formulated to target broadleaf weeds while sparing the grass around them, which is the core reason lawn-specific weed killers exist rather than a general vegetation killer. Timing and application rate matter for effectiveness and lawn safety, so reading the label thoroughly before spraying is worth the few extra minutes.
Pros and cons
Pros
- Effective against a wide range of broadleaf weeds
- Selective formula, designed to spare grass
- Well-established, widely used product
Cons
- Requires careful label reading for grass-type compatibility
