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.

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...

No Success

I used this product as the instructions stated but received negative results. It was 0% effective on my yard, so I’m very hesitant to try it again. I was hoping for success, but it looks like I’ll have to switch to another weed control product.

Them weeds be dead

Not sure why these other people are saying it didn’t work. It killed almost all of my weeds. Did use a lot more product than expected but it killed the weeds without harming the grass.

No Dead Weeds in Our Florida Lawn

This weed killer came with our lawn plan. I applied as directed, and not one weed was killed in our Florida lawn. About a month later, I bought an Ortho product, and that did the trick. Dandelion Doom is worthless.

Waste of Money

Should have listened to the other negative reviews before buying. Followed directions, applied in sunny/dry conditions, and even applied to a variety of different weeds. It's been two days, and every single weed is still alive and well.

Great Product

I used this product approximately 24hrs ago on my lawn on both clover and some broad leaf weeds and I can see it working already. The weeds have already browned and are shriveling while the grass has remained healthy. I used this product with some level of skepticism after reading the other reviews ...

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 a...

Doesn’t kill Zoysia

Really happy to have finally found a product I can spray on my Zoysia lawn that doesn’t kill it! So nice to not have to get on my hands and knees anymore to pull the weeds from my lawn. So happy to have finally found this product! You guys rock!
