INSTRUCTIONS

For best results, apply between 50-85 degrees F when no rain is expected for 3+ hours

  1. Pour one full bottle of Dandelion Doom concentrate into the reusable pouch and attach the sprayer
  2. Use your outside hose to fill the pouch up to the 1-gallon mark. Secure the cap of the reusable pouch and shake well.

  4. Repeat treatment in 3-4 weeks, or as needed. Store your wand sprayer and pouch for future use

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*.

Did nothing for my weed covered lawn :(

Unfortunately, Dandelion Doom Weed Killer did nothing for my lawn. I drenched the leaves and spread heavily throughout but the lawn is still riddled with weeds! Some areas now have more weeds than before. I have also seeded twice after applying and I'm still under a bed of weeds.

Killed my lawn

This killed about 5% of the weeds and killed 100% of the grass it was sprayed on. There's just big black spots on my lawn wherever I sprayed this. It looks like I torched my grass.

Worst product ever!

Purchase this for the first time (and last) to kill some dandelions coming in the yard. Sprayed and could tell zero affect after a day. Even more dandelions started coming in and I feel like it was a fertilizer more than a weed killer. Maybe I received a bad batch

Hi Zac, 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.

Dandelion Doom??? More like Dandelion Boom!!

I just subscribed to your lawn care program, and I was excited to try the Dandelion Doom that was sent to me.   So far, I have to say I am far from impressed with your product.   I followed the instructions for that spray, and I am not sure it killed even 1 dandelion in my yard.   I truly hope your ...
