Your complete spring lawn care plan, in a box

The Spring Starter Kit is a three-product spring weed and feed system. Grass Powerhouse drives thicker, faster growth (24-0-3). Iron Boost deepens that rich green color (20-0-1). Dandelion Doom targets dandelions, clover, chickweed, spurge, and oxalis with iron-based weed control. Alternate fertilizers every 4 to 6 weeks and spot treat as weeds appear. Build a custom plan.

What makes Spring Starter Kit different

  • Two liquid fertilizers, 24-0-3 and 20-0-1
  • Iron-based weed control, no harsh chemicals
  • Hose-end sprayer and wand sprayer included
  • Works on all common grass types
  • Alternating schedule for sustained feeding
  • Pesticide-free fertilizers, all season long

What's included

Grass Powerhouse (24-0-3), a 16 oz. hose-end pouch covering up to 5,000 sq ft. Iron Boost (20-0-1), a 16 oz. hose-end pouch covering up to 5,000 sq ft. Dandelion Doom Concentrate, a 5 oz. bottle covering up to 224 sq ft. One hose-end sprayer and one wand sprayer are included so you can start right away.

How to use

Start when soil temperatures hit around 55 degrees F and daytime temps are between 50 and 85 degrees F. That is your green light for spring. Not sure what weeds you have? Use the weed ID guide.

  1. Attach Grass Powerhouse to the hose-end sprayer. Apply evenly across your lawn.
  2. Wait 4 to 6 weeks, then swap to Iron Boost. Same sprayer, same process.
  3. Spot treat broadleaf weeds anytime with Dandelion Doom. Mix the concentrate in the pouch, attach the wand sprayer, and spray directly on weed leaves. Works on dandelions, clover, chickweed, spurge, oxalis, moss, algae, and lichen. Expect visible wilting in 24 to 72 hours and full results in 1 to 2 weeks.
  4. Keep alternating Grass Powerhouse and Iron Boost every 4 to 6 weeks through the season.
  5. Skip fertilizer if rain is expected within 4 hours or your lawn is heat-stressed.

Does the Spring Starter Kit include weed control?

The Spring Starter Kit includes Dandelion Doom Concentrate, an iron-based weed control that targets dandelions, clover, chickweed, spurge, and oxalis.

Spray directly on weed leaves with the included wand sprayer. Visible wilting appears in 24 to 72 hours.

What order should I apply the three products?

Start with Grass Powerhouse fertilizer across your full lawn using the hose-end sprayer. Four to six weeks later, switch to Iron Boost using the same process.

Spot treat broadleaf weeds anytime with Dandelion Doom. Let the weed control dry completely before applying fertilizer to the same area.

Will the Spring Starter Kit help with clover in my lawn?

The Spring Starter Kit includes Dandelion Doom, which targets clover along with dandelions, chickweed, spurge, and oxalis using iron-based weed control.

Spray clover leaves directly until covered. Expect visible wilting within 24 to 72 hours. Stubborn patches may need a second application.

When should I start using the Spring Starter Kit?

Apply the Spring Starter Kit when your grass is actively growing and soil temperatures reach around 55 degrees F. For most regions, that means mid-March through April.

Apply when air temperatures are between 50 and 85 degrees F. Skip fertilizer if rain is expected within 4 hours.

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

The Spring Starter Kit is designed around an alternating schedule. Apply Grass Powerhouse first, then switch to Iron Boost 4 to 6 weeks later.

Alternating gives your lawn steady feeding through the season without overlap. Do not apply both fertilizers at once.

How is the Spring Starter Kit different from a traditional weed and feed?

The Spring Starter Kit separates fertilizer and weed control into three products. Grass Powerhouse and Iron Boost are pesticide-free liquid fertilizers. Dandelion Doom uses iron-based weed control.

You apply weed control only where weeds appear, not across your entire lawn.

    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’t want to waste my money to purchase more since it didn’t work the first time. I’m really disappointed and am not sure if I’ll even use the rest of their products I bought. The good thing is I didn’t buy their re-curing plan of products.

    Thanks for sharing your feedback regarding Dandelion Doom! This is a selective herbicide, which means that it is designed to target broadleaf weeds like dandelions, and not certain other weeds. We encourage you to reach our to our expert Yard Advisor team to get more information on the weeds that Dandelion Doom is effective on. You can reach them at [email protected].

    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!

    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 the north face of a hill so we have shade loving plants, mosses and ferns. I have some neighbors who have spent thousands ripping out their lawns and bringing in soil and new grass seed. Others have their lawn spray painted green by the chem lawn companies. I prefer a softer more gradual approach.

    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 Mosquito.

    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 green and we are loving the products from Sunday!
