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.

What's doing the work

  • Fast growth and deep color Two liquid fertilizers that alternate every 4 to 6 weeks through the season
  • Targeted broadleaf weed control Iron-based concentrate spot-treats dandelions, clover, and more without harming grass
  • Zero pesticides Both fertilizers are pesticide-free. Dandelion Doom is iron-based.
  • Tools included Hose-end sprayer and wand sprayer for both application methods
  • Backed by our satisfaction guarantee

What's included

  • Grass Powerhouse (24-0-3) 16 oz. hose-end pouch, covers up to 5,000 sq. ft.
  • Iron Boost (20-0-1) 16 oz. hose-end pouch, covers up to 5,000 sq. ft.
  • Dandelion Doom Concentrate 5 oz. concentrate, covers up to 224 sq. ft.
  • Herbicide pouch, hose-end sprayer and wand sprayer included

How to use

  1. Apply Grass Powerhouse evenly across your lawn with the hose-end sprayer at temperatures between 50 and 85°F.
  2. Four to six weeks later, swap to Iron Boost. Same process.
  3. Spot treat weeds anytime with Dandelion Doom. Mix in the pouch, attach the wand, spray weed leaves. Broadleaf weeds only. Not sure what you have? Use our weed ID guide.

Skip fertilizer if rain is coming within 4 hours or your lawn is heat-stressed.

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.
