FAQ

What weeds does Dandelion Doom kill?

Broadleaf weeds including dandelions, white clover, chickweed, creeping charlie, ground ivy, oxalis, and bull thistle. Also kills moss and algae. Does not control grassy weeds like crabgrass, for that try Weed Warrior.

Will it kill my grass?

No. The formula is selective. Broadleaf weeds absorb iron in a way that's toxic to them while your grass tolerates it. Works on all cool and warm season turf when used as directed. Apply within the 50 to 85°F window for best results.

How long does it take to work?

Visible wilting starts within hours on actively growing weeds. Full results within 1 to 2 weeks. Established weeds may need a second application 3 to 4 weeks later.

Can I use this on my whole lawn?

This formula is for spot treating individual weeds. For heavier weed pressure across a larger area, Dandelion Doom Concentrate with a wand sprayer is the more efficient choice. No sprayer? These bottles work across the whole lawn one spot at a time.

Is the 2-pack worth it over buying one bottle?

Weeds show up in spring and again in fall. Stubborn ones need a second round. One bottle rarely covers a full season. Two keeps you stocked without thinking about it.

Is it safe for kids and pets?

This is made from one active ingredient, iron. No harsh chemicals, ever. So people and pets can return to the area once the spray has dried.

Fast working and effective!

I used the small wand with a pouch and sprayed each dandelion plant individually. Before spraying, my yard looked like my neighbors. 24 hours later, they are dying nicely!

Mixed Results

Dandelion Doom does seem to kill dandelions but it's a long, slow process. I sprayed a week ago and saw the dandelions start to wilt within hours. However, a week later, they're not dead yet and during the slow kill process, the dandelions have produced a lot of blooms that are going to seed, before...

Product Works Great

I used this product on dozens of weeds we had and they were all dead by the next day. The downside was that after some rain, a few days later many other weeds had grown in their place. I need something to spray this on my entire lawn.

Didn't work :(

I used an entire bottle spraying each dandelion plant in our yard and none of them died!!!!

Sunday

Hello K, Ugh, that’s frustrating—we’d expect at least some dandelion drama after a full bottle. Most likely the spray didn’t fully absorb (waxy leaves can be sneaky), so try reapplying on a warm, dry day and really coat the leaves, not just the flower. If they’re still standing proud, Sunny (our yard expert) can help dial in the approach for your exact lawn so we can finally evict those freeloaders

Mixed results. Some great, some just ok.

worked like a CHARM last year. This year seems to be more of a challenge. Also when I used iron boost last year, it seemed to somehow prevent almost all the dandelions from blooming. The ones that did bloom last year were zapped right away with the dandelion killer. This year maybe I was late to spr...

Dandelion boom…

After emptying 4 gallons on hundreds of dandelions, I’m here to report that not even one died. This product is like dumping water on them.

Sunday

Hi Stephen, I'm sorry to hear about your experience with our product. That’s frustrating, and definitely not the result we’re going for. Dandelion control works best when sprayed directly on the leaves on a warm, sunny day so the formula can fully absorb and do its thing. If you’re up for it, our yard advisors can help troubleshoot and get those weeds waving the white flag—we’ve got your back

Kills grass

I tried this on my lawn o. Clover and other leafy weeds, but it killed my burmuda grass as well and didn’t do a great job on the actual weeds.

Sunday

Hello Allison, we're sorry to hear that, that’s definitely frustrating when your grass takes a hit and the weeds stick around. Dandelion Doom is designed to target broadleaf weeds without harming turf, but Bermuda grass can sometimes be more sensitive, especially in heat or if the lawn is already stressed. In the meantime, watering the lawn deeply but infrequently can help your grass recover and strengthen roots. We’re here to help you get things back on track and dial in the right approach for your lawn.

Didn't work

I really wanted this to work. I took a picture of the plants I was having problems with and this was the recommendation I got. I've applied both bottles, saturating all of the weeds. The bottle says you should see results in a few hours, but 24 hours later and everything is still doing fine, even th...

Sunday

Hi Nick, I'm sorry to hear that our product didn't meet your expectations. We really appreciate you giving it a shot—and sharing the details here. Dandelion Doom should start showing visible changes within a day, especially on true dandelions, so if everything looks untouched after 24 hours, that’s not the experience we want you to have. A couple factors like weed type, maturity, and coverage can impact results—but even then, you should be seeing something. Glad to hear your grass is doing okay—that part matters too. If you’re up for it, send us that photo you mentioned and we can help ID what you’re dealing with and recommend the right next step (or make this right for you)

Great product

I have been using this product for several years on a very resistant bull thistle that kept popping up all over my yard. It kills it dead in a few hours. I like that it is not poison and won't harm the environment or my kids or pets. It is super effective for spot treating only the weeds you want to...
