The spring glow-up starts here

Grass Powerhouse delivers nitrogen, iron, and seaweed to fuel thick growth and build stress resilience. Iron Boost follows with our highest iron concentration for color so deep it borders on showing off. And Dandelion Doom takes out broadleaf weeds while your grass stays untouched.

One kit. One season's worth of good looks.

The good stuff inside

  • Growth + resilience Grass Powerhouse (24-0-3) fuels thick, healthy turf with seaweed-powered stress defense
  • Deep greening Iron Boost (20-0-1) for fast color correction and iron-hungry lawns
  • Lawn-safe weed control Dandelion Doom targets dandelions, clover, and other broadleaf weeds
  • Precision tools Wand sprayer and pouch for easy, targeted spot treatment
  • Easy application Attach, spray and you’re done

How to use

Apply early morning or evening, between 50–85°F, to a hydrated lawn.

  1. Mix Dandelion Doom in the herbicide pouch, fill to the 1-gallon line, shake gently.
  2. Attach wand sprayer and target weeds directly. Let dry. Repeat in 3–4 weeks if needed.
  3. Attach hose-end sprayer to Iron Boost fertilizer pouch, spray your lawn evenly.
  4. Reapply fertilizer every 4–6 weeks, alternating Grass Powerhouse and Iron Boost.

What's the best spring fertilizer for a green lawn?

A nitrogen and iron-forward liquid fertilizer gets grass growing and greening fast after winter. Grass Powerhouse (24-0-3) handles growth and resilience. Iron Boost (20-0-1) adds deep color, especially if your soil is iron-deficient. Alternate them every 4–6 weeks.

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

Use an iron-based selective herbicide. The iron (FeHEDTA) in Dandelion Doom targets broadleaf weeds while leaving grass unharmed. Spray directly on weed leaves until covered and repeat in 3–4 weeks for stubborn ones.

When should I start fertilizing my lawn in spring?

Start when your grass is actively growing and soil temps hit around 55°F. For most areas, that's mid-March through April. Apply in early morning or evening when temps are between 50–85°F, and make sure your lawn is hydrated first.

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 before the next goes down.
