So far it looks like this really WORKS!!! My lawn is greening up beautifully, and the (many) weeds have become fewer... need a few more weeks, and then a second application to really give it a proper review.

But so far, so good.

Hello Bobby, thank you so much for the fantastic 5-star review! We are thrilled to hear that the Fiesta Granular Weed and Feed 8-0-1 is already showing great results and that your lawn is greening up beautifully.

You are exactly right, while the initial green-up and early weed control happen quickly, following up with a second application a few weeks later is the perfect way to target any remaining stubborn weeds and establish long-term control.

We look forward to your follow-up review after the next application. Thank you for choosing us for your lawn care needs, and have a wonderful growing season! 🙌

At first I didn't think the product was working:( It took about 4 days and now I'm seeing dying weeds! YAYYY! I will be applying a second application, because I want those suckers dead dead. Lol.The icing on the cake is that this product is organic. I LOVE that! You have a new loyal customer. THANK YOU! 😊

Thank you for the wonderful 5-star review, Shawntina! We are so glad to hear that you are seeing those weeds die off and that you love using an organic solution for your lawn.

You are exactly right a second application can be very helpful for knocking down those tougher weeds completely. We truly appreciate your support and are thrilled to welcome you as a loyal customer!

It took a few tries to get the application rate to be right and uniform, but now the results are great! And it’s so fast! I find it much easier than the liquid Fiesta I had been using, and it fertilizes to boot!

Thanks so much for sharing your experience!

Works good but be patient

When I first applied the Fiesta granular weed and feed I wasn’t sure it was doing much but it was. I have killed most of my broadleaf weeds. It’s been two months and I am hitting the lawn with second round of Fiesta. Will review again later.

Thank you for sharing your experience with Fiesta Granular Weed and Feed! We’re glad to hear that after a bit of patience, you saw strong results against broadleaf weeds. The second application is a great step toward keeping your lawn in top shape. We appreciate you taking the time to leave feedback and look forward to your next update!

It works!

Works very well if you use enough, and reapply as indicated. I have a huge yard, so this is a major timesaver over the liquid version! By the time our soil warmed enough to be 50 degrees, our many dandelions were quite large, so I applied and the highest rate listed and it totally wiped all of them out in 1 big area, and came close for the rest of the yard. It's pricey for a big yard, but such a a relief to have a healthy, effective, and quick way to get rid of a sea of dandelions!

Thank you for the fantastic review! We're so glad to hear that the Fiesta Granular 8-0-1 delivered strong results, especially on those larger dandelions once your soil warmed up. You're absolutely right—using the proper rate and timing can make all the difference, and it’s great to know it saved you time compared to the liquid version. We appreciate your honest feedback on the cost for larger areas and are thrilled it brought you the relief of a healthier, weed-free lawn. Thanks again for trusting us with your yard care! :herb:

I followed the instructions and saw no difference to the weeds. I’m disappointed in the amount of money I spent on this for no results.
