Helpful Tips from Lawn Advisors:

How does this 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.

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.

*Not approved for this use in California. Please see CA label for all approved use.

Do I need the Dandelion Doom Starter Pack to use this product?

Yes, these are refill concentrates only. You'll need the sprayer and pouch that come with the Dandelion Doom Starter Pack or Starter 2-Pack to apply this product.

How many applications will I get from this 2-pack?

Each bottle treats up to 224 sq. ft. of lawn area, so the 2-pack provides enough concentrate for two separate applications at this coverage, or one application over a larger 448 sq. ft. area.

How to use Dandelion Doom with other Sunday products?

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

Does Dandelion Doom stain?

It can cause staining due to high iron formula. Avoid using on sidewalks or hard surfaces. If you spill, immediately rinse the area. For best results, mix over lawn or landscape

Are there any US states where this is not approved for use?

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 th...

Do NOT buy

I have the subscription and submitted my lawn soil for analysis. I applied the Dandelion Doom Concentrate and my weeds are still growing. Its been 2 months, with little to no progress in weed control.

Not feeling confident

I thought I would try and maintain my lawn with Sunday. Started with the kick starter followed by the dandelion doom and southern lawn. 2 months in and I think if I did nothing, it would be the same. Maybe I just dont know what I’m doing but I’d rather pay a company and enjoy the freedom.🤷‍:male_sig...

Ineffective

With having 3 dogs, I was hoping to have found a pet friendly weed killer for the backyard. Unfortunately it isn't effective at killing all the weeds. It killed about 75% of the dandelions, but that is all. It did nothing to the clover, thistle, crabgrass, etc.

Store Owner

We're sorry to hear that your weed control results aren't as expected! Here are some Best Practices to follow for best results. 1.) Try to apply on a sunny day. While not mandatory, sunshine will improve the efficacy and speed of our herbicides. With sunshine unfiltered by clouds, our herbicides will work even better. A rainfall within 3 hours after application can make the herbicides ineffective. Optimal temperatures for application are between 50F to 85F. 2.) Apply when the weeds look healthy. When weeds are stressed or injured, weeds release hormones to recover. These hormones make herbicides less effective. Hormones are also released if weeds are mowed; we recommend not applying on the same day you mow. 3.) Apply the leaves liberally. Our herbicides just need to make contact with the leaves to work; trying to apply to the roots won't be effective. For best results, you want the leaves soaked, but not to the point where the herbicides is dripping off the leaves. 4.) Know the age of the weed. Older and established weeds will likely require more applications. For older weeds, we recommend doing multiple applications on the same day; just let the leaves dry out in-between applications.

Kills Bermuda grass

Really wanted this product to work but unfortunately, it does indeed leave the surrounding grass around the targeted weed black and dead. In addition, I subscribed for a year of lawn care. All I have been sent for weed control is this product. I now have weeds taking over my lawn and a simple sport ...

Dandelion Doom not up to the task

First off, the original battery powered sprayer they sent me did not work, had to wait an extra week for new one to arrive. Then thoroughly applied to weeds, saw little to no effect. Waste of money. Should have put the money towards a lawn care service that will actually accomplish the job. Save you...

Did not work at all

Purchased this from Walmart for 28 dollars, lots of dandelions in various stages of growth in lawn.Applied as directed with no results. Applied again with no results again. Used almost the entire gallon and it was a waste of time and money. Being on a fixed income I am very disappointed.

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.

Dandelion Doom

Dandelion Doom was included in my first box. I didn’t need it for my lawn but used on my daughter’s lawn and it did an amazing job.

Works wonders on Dandelions

Works great on Dandelions, just don't use it on much of anything else because it won't really impact those other weeds. The weed control products are pretty expensive through Sunday. I really wish that they would go on sale because that way I could stock up and use them through out the year.
