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

Killed my lawn

I applied the this yesterday and woke up today to a completely dead lawn. It was heading in the right direction and now it’s a disaster. Is the dandelion spray supposed to kill all of your lawn???

We ordered and paid for Dandelion Doom on 6/14/24 but still haven't received a month later!

We ordered Dandelion Doom Herbicide Concentrate Refill (2-pack) on 6/14/24 and our credit card was processed and charged on 6/15/24 but we never received our order.

Added more weeds to my lawn

My front and back yards are not connected. I have cement and space between each. My back yard had a small amount of thistle in one area, for many years, has NEVER spread before. I used to just mow over them and they would grow back slow. I had dandelions from my front yard neighbor. I purchased the ...

Store Owner

We're sorry to hear that your experience was not as expected! If you've recently raked or tilled your area in order to spread new seed, you may have disturbed a seed bank in your lawn, which can lead to new weeds that you haven't experience before. It sounds like the thistle in your lawn was well-established; these mature weeds can require multiple applications of weed control. For best results, apply in direct heat and sunlight, and try removing any seed heads and splitting the stems of mature weeds before applying weed control.

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 ...

Works but….

Removed some of the weeds but left brown marks in the grass, possibly grass damage. Initially thought it was rabbit pee.

Effective but scorched my yard

It was pretty effective in killing the dandelions in my backyard, but it also killed the grass. In the areas where I sprayed dandelion doom, my grass looks scorched. It was completely ineffective on my front lawn.

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...

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.
