FAQ

What's the best lawn fertilizer for spring?

Liquid fertilizer with nitrogen and iron absorbs fast and gets grass growing after winter. Grass Machine (15-0-3) combines nitrogen, iron, and seaweed for growth and resilience. For deeper greening, alternate with Iron Boost (20-0-1) every 4–6 weeks.

How do I get rid of dandelions without killing my grass?

Use an iron-based herbicide like Dandelion Doom or Weed & Green. The iron (FeHEDTA) in both formulas targets broadleaf weeds while leaving grass alone. Spray directly on leaves until covered and repeat in 3–4 weeks.

Is this safe for pets and kids?

Yep. Once everything's dry (usually a few hours) you're good to go. No synthetic herbicides, no waiting days to use your yard.

Can I apply weed killer and fertilizer the same day?

You can. Weed killer first, let it dry (2–3 hours), then fertilize. Each product needs time to absorb and dry before the next goes down.

Dandelion Doom didnt work for me

I purchased the Spring Starter kit, which included Dandelion Doom. I used it as my first product (and only at this point) and followed directions to a t. It literally did absolutely nothing to my lawn weeds. I also sprayed it along my fence line and those weeds are still happy as can be, too. I don’...

Kick start definitely kick started our lawn

Our back yard was pretty much bare and muddy with dormant Bermuda grass. With 2 large active dogs overseeing was out of the question. In desperation I applied Kick Start and within a week the Bermuda grass is coming back. I see new grass coming up all over. Very happy home owner here...

I just love Mosquito Deleto

Easy to apply and it smells pleasant. I had used several other natural products before but the smell was pretty much unbearable, plus the sprayers usually drenched me. Mosquito Deleto is easy to apply without any back spray and it smells nice. Like it so much I just ordered 2 more bottles.

Awful

Review by Anonymous User This whole thing is a scam. We have more weeds than we have ever had in our yard. We have way more success using what our local hardware store has

Sunday

Sunday nutrients will improve soil health, encouraging thicker and fuller grass growth. However, our fertilizer pouches/bags do not contain any herbicides, so they alone will not directly treat existing patches of weeds. For assistance with our weed control products and to make the most of your Custom Lawn Plan, you can always reach out to your Yard Advisor! You can reach them at [email protected] or by calling 415-903-6932.

Just right for me.

This kit is easy to use and comes with everything you need to get started. The results are good but not dramatic. It’s not advertised as a dramatic improvement, but rather a process that depends on the time and resources you dedicate to it. i live in a neighborhood in the north, and the house is on ...

Just ok.

First time using Sunday. Anticipated a thicker green yard. The weed control was not affective against clover in the grass. I did not see the results I expected. This may not be related, but I have had extensive mole damage this year for the first time. I did like the Nix Ticks product and Deleto Mos...

Got things going!

We felt safe using these products around our kids and dogs. It really greened up the grass but the weed killer probably needs a few coats to really make it count. So far we will be buying again!

Great product with great results

We have 4 Basset Hounds, so we wanted something pet friendly. The kickstarter kit worked great and really brought our lawn back to being green and full. We had weeds and dead patches in our lawn before using the kickstart kit and it really got it going in the right direction. Our lawn is thick and g...
