Here's an honest breakdown of how they compare, what they're best at, and which one might be the right pick for your yard.

What is Spruce weed killer and how does it work?
Spruce is a non-selective contact herbicide made by P&G. Its active ingredients are geraniol and cornmint oil (both essential oils), supported by sodium lauryl sulfate, isopropyl alcohol, and triethyl citrate.
It works on contact, meaning it damages the plant tissue it touches. Spruce claims visible results in about 1 hour and comes with a built-in power wand sprayer for easy application.
You can find it at Home Depot for around $29.97 (64oz Power Wand).
What is Sunday Weed Warrior and how does it work?
Sunday Weed Warrior is a herbicidal soap made from ammoniated soap of fatty acids. It's OMRI-listed, which means it's certified for organic gardening by a third-party organization.
Like Spruce, it's a non-selective contact herbicide. But Weed Warrior shows visible results in as little as 20 minutes. It's non-staining and comes ready to use in a trigger sprayer.
Pricing is straightforward: $17.60 for a 2-pack (two 32oz spray bottles), or $22 for a 27oz concentrate refill that covers about 224 sq ft.
How do the ingredients compare?
Both products skip harsh chemicals and get the job done with plant-derived or soap-based ingredients. The biggest differences: Weed Warrior works faster, costs less, and carries OMRI organic certification.
Are Spruce and Sunday weed killers safe for pets and bees?
Both products use plant-derived ingredients and skip traditional herbicides like glyphosate. Neither contains harsh chemicals.
The key difference is verification. Sunday Weed Warrior is OMRI-listed, which means its ingredients and formulation have been reviewed and certified by a third-party organization for organic use. Spruce relies on essential oils and does not carry that certification.
Both take a gentler approach to weed control than conventional options.
What weed control options does Sunday offer beyond Weed Warrior?
This is where the two brands really diverge. Spruce offers a single product. Sunday offers a full system.
- Dandelion Doom is an iron-based (FeHEDTA) selective herbicide that targets broadleaf weeds like dandelions and clover without harming your grass. That's a big deal if you want to treat weeds in your lawn, not just on driveways and sidewalks.
- Weed & Green combines pre- and post-emergent weed control with fertilizer, so you're feeding your lawn and stopping weeds at the same time.
- Custom lawn plans are built from real data: over 1 million unique soil profiles, satellite imagery, local climate patterns, and your specific grass type. Your plan adapts as conditions change.
- Expert support is available from US-based Yard Advisors by phone, text, or video chat, plus Sunny, Sunday's AI yard companion, available 24/7.
- The Sunday Guarantee backs everything up with replacements, expert troubleshooting, and a commitment to make it right.
Spruce handles spot treatment well. Sunday handles the whole yard.
Which weed killer is right for you?
Both are legitimate options, and the best choice depends on what you're looking for.
