Kill weeds, not your grass

Dandelion Doom is a post-emergent iron-based weed killer, designed to target broadleaf weeds, moss, and lawn diseases. Its iron-rich formula is harmful to weeds yet safe for lawns.

This reusable 1-gallon herbicide kit, equipped with a premium battery-operated wand sprayer, ensures efficient weed control.

Effective against broadleaf weeds like black medic, plantain, thistle, chickweed, creeping buttercup, creeping charlie, dandelion, geranium sp., English daisy, false dandelion, healall, oxalis, speedwell sp/, knotweed, shepherd’s-purse, silverweed cinquefoil, white clover, wild chamomile, as well as moss, liverworts, algae and lichens. It can also control or suppress lawn diseases: dollar spot, rust and/or snow mold.

Helpful Tips from Lawn Advisors:

How does lawn-safe weed killer work?

Grass and weeds absorb iron differently. Weeds quickly take in too much iron, which becomes toxic and kills them. Grass absorbs iron more slowly and can tolerate higher amounts. This difference allows us to target weeds while giving your lawn a healthy, deeper green color.

How to use Dandelion Doom with other Sunday products?

You can apply weed killer, like Dandelion Doom, before or after lawn fertilizer. Allow weed control products to dry completely before applying any other Sunday liquid products or watering your lawn–the longer the plant absorbs the weed control, the more effective the application.

When will I see results?

Fully drenched weeds will dry up in as little as 20 minutes or up to 24 hours, depending on the size and maturity of the plant you are spraying.

What weeds does Dandelion Doom control?

Dandelion Doom is effective on broadleaf weeds like black medic*, broadleaf plantain, bull thistle, Canada thistle*, common chickweed*, creeping buttercup, creeping charlie/ground ivy*, dandelion, dovefoot geranium*, English daisy*, false dandelion, healall*, moss, liverworts*, algae* and lichens*, narrow-leaved plantain*, oxalis, Persian Speedwell, prostrate knotweed*, shepherd’s-purse*, silverweed cinquefoil*, slender speedwell*, white clover, wild chamomile*.

It can also control or suppress diseases such as but not limited to*: Dollar Spot, Rust or Snow Mold.

Sunday Customer Service is Great

I used Dandelion Doom without success. I left a review and Sunday contacted me and worked though the issue with *and actual person*. They explained what may have happened and they sent me a different product to try after looking at pictures of the weeds in my lawn that I sent. Kudos for the advice and service!

Wow… it killed them all!

This was my first time using dandelion doom. We are up in Bozeman MT with unpredictable weather right now but I made sure to choose the right day - sunny and warm with emerging, healthy dandelions (covering pretty much our entire lawn, they were out of control this year). So I took my time spraying each one, really saturating the leaves and flower...Read More

s. It took 3 bottles of dandelion doom and a good amount of time but I just slowly worked through. By the next day they were all withered and the next day they were completely brown and dead. I am so impressed at how well this worked. Will definitely follow up in 4 weeks and hopefully get control of the dandelions over time. Read Less

White clover taking over

I couldn't be happier with the Dandelion Doom Concentrate. It was much easier to use than the smaller spray bottle of the same product esp in large applications. My entire yard was being taken over clover. You could see it start working within hours after applying. Now with the rain here in the PNW i would suggest 2 applications of the product. Im...Read More

Skepticism erased!

I applied it with no rain in forecast. However, the following morning it was evident that a light rain fell overnight (darn! would it inhibit the Dandelion Doom?). In the sunny afternoon I went to apply additional spray and to my surprise discovered dozens of nearly-black dandelions looking as if they'd been... bombed! Accurate name for the produc...Read More

Thistle Problem

We had a thistle problem in our yard this year, they were everywhere. Dandelion Doom killed every single one of them. It did take about two days for it to work, but once it did they died fast. I bought two more bottles for next year.

This was the 1st SUNDAY

This was the 1st SUNDAY product I tried. I sprayed it on clusters of flat deep rooted weeds that had intertwined with the bermuda grass all over the yard. Almost immediately the weeds turned black. I tried to dig them out but the roots were so deep and broad it left holes in the ground. after a couple of hours of hard digging, pulling I left them....Read More

As they died out, over the next weeks, the grass started growing over them and covering them up! (I had applied the first lawn treatment by then). So now there's no trace of those huge clumps of flat weeds and all solid new grass growth -- it looks great and knowing I didn't use harmful herbicides feels great! Read Less

I love Dandelion Doom. I

I love Dandelion Doom. I love I'm not using poisons on my lawn. I watch dandelions turn a black ash color and then " gone , gone baby". It works even on my creeping Charlie weeds. I will say be careful and not spray it near drip line bushes, ex. Viburnum. It did destroy a branch of my viburnum. But I highly endorse this product.

Works great at killing weeds but not your grass. Typically, I start to see results within a few minutes. Unlike the chemicals that other weed killers use, Dandelion Doom kills the dandelions without the harsh chemicals.

Works as described

Worked great! I applied to a patch of clover and broad leaf undesirables and within a day, they were wilted. The following day the undesirables had turned black. The grass looks fine. I got out my phone and ordered enough to treat the rest of my yard.

Q: I have several weeds in my lawn, some dandelions, some creeping Charlie, clover, and others that I don’t even know what they are. I’m not sure what to do. Do you have a weed killer that I could attached to my hose and one that will kill all those weeds that I mentioned. I’m at a loss as to what to do. It’s a project. They have to tackle myself, which is not easy for a 79-year-old woman. Please let me know if you have any suggestions. Thank you

Q: Is this harmful if you have a well on property and have well water?

06/10/24

A: Sunday is a precision fertilization program, focused on giving your lawn nutrients when it needs them.

Our products are foliar-fed meaning the grass can absorb nutrients immediately, effectively, with lower chance of runoff. When used as directed, Sunday shouldn't affect your well water at all.

Q: Can I use Dandelion Doom in the summer when the temperatures are already above 90?

05/29/24

A: For best results, we recommend applying Dandelion Doom spring through fall when outdoor temps are between 50–85º F, and weeds are actively growing.

Mari

05/19/24

Q: We just used your fertilizer for southern lawns and it's working great. Dollar weed is being pushed out but we need a weed and feed next, correct? Please help me understand which one is for lawns. Thanks, Mari

05/20/24

A: Sunday nutrients will improve soil health, encouraging thicker and fuller grass growth. However, our fertilizer pouches/bags do not contain any herbicides, so they alone will not directly treat existing patches of weeds.

To help with those pesky weeds, we offer a variety of weed control products. They can be added in a recurring fashion (as part of our plan bundles), or as an add-on from our Shop here: https://www.getsunday.com/shop/category/lawn-care/weed-killer
