Spring lawn care in three steps

Four weeks from now, your lawn could be thicker, greener, and weed-free. This kit is built to get it there.

Grass Powerhouse handles the growth. Iron Boost handles the color. Dandelion Doom handles the broadleaf weeds. Alternate the two fertilizers every 4 to 6 weeks and spot treat weeds as they appear. Your lawn does the rest.

Three products. One spring. Everything works together so you don't have to figure out what to buy or in what order.

FAQ

When should I start using this kit in spring?

When your grass is actively growing and soil temps are around 55°F. For most regions that's mid-March through April. Apply in early morning or evening when temperatures are between 50 and 85°F and your lawn is hydrated.

What order do I apply the products?

Dandelion Doom first. Apply to targeted weeds and let dry fully, about 2 to 3 hours. Then apply whichever fertilizer is next in your rotation.

Can I apply Iron Boost and Grass Powerhouse on the same day?

No. Alternate them every 4 to 6 weeks rather than applying both at once. The alternating schedule gives your lawn steady feeding through the season without overlap.

Does Dandelion Doom kill all weeds?

No. Dandelion Doom targets broadleaf weeds including dandelions, clover, chickweed, spurge, and oxalis. It also controls moss, algae and lichen, and even suppresses lawn diseases. However, it does not control grassy weeds like crabgrass.

How soon will I see results?

Fertilizer results typically show within 24 to 48 hours. Weed control results take 24 to 72 hours for visible wilting and 1 to 2 weeks for full results. Stubborn weeds may need a second application.

How long after applying is it safe for kids and pets?

Once the lawn is fully dried, kids and pets can return to the area. No harsh chemicals. No yellow warning flags needed.

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...
