Your lawn's summer survival plan, in one box

Summer Heat Defense Kit is a summer lawn care kit that tackles heat stress, drought, and broadleaf weeds in one box. Treat weeds with iron-based Dandelion Doom, lock in moisture with Water Focus, then strengthen roots with Lawn Aid. Sprayers included. Pair with your Custom Lawn Plan or add Drought Defense for peak heat.

What makes Summer Heat Defense Kit different

  • Heat stress prevention and weed control in one kit
  • Iron-based herbicide that won't harm your grass
  • Seaweed extract and potassium strengthen roots
  • Surfactant helps soil hold water longer
  • Sprayers included, hooks up to your hose
  • Works on most residential turfgrass types

Ingredients

Lawn Aid (0-0-3): Potassium for heat and drought tolerance. Seaweed extract for deep greening, turf density, and stronger root systems.

Water Focus: Surfactant for water retention. Slow-release nitrogen for sustained growth. Potassium for better water management. Molasses to feed soil microbes and support healthy soil biology.

Dandelion Doom: Iron-based active ingredient, that targets broadleaf weeds in high doses. Grass has a higher iron tolerance, so it stays unharmed. Also helps suppress lawn diseases like dollar spot, rust, and snow mold.

How to use

Apply when temperatures are between 50 and 85 degrees F. Early morning or late evening works best on a well-hydrated lawn.

  1. Spot-treat weeds first. Mix Dandelion Doom concentrate in the included wand sprayer pouch. Spray dry weeds from a close distance until drenched. Wait 20 to 30 minutes, then pull and dispose of remains.
  2. Wait at least 24 hours before applying nutrients. Treating weeds first keeps them from feeding on your fertilizer.
  3. Apply Water Focus. Connect the hose-end sprayer to your hose and the pouch. Distribute evenly in a sweeping motion until the pouch is empty, about 10 to 15 minutes.
  4. Wait two weeks, then apply Lawn Aid the same way. This spacing gives each product time to do its thing.
  5. Water thoroughly after each nutrient application. Reapply Lawn Aid every 4 weeks from spring through fall, up to 8 times per year.

How soon after applying Summer Heat Defense Kit should I water my lawn?

Water your lawn thoroughly right after applying Lawn Aid or Water Focus from the Summer Heat Defense Kit.

For Dandelion Doom, do not water for at least 3 hours so the iron-based formula has time to work on weeds.

Can I use the Summer Heat Defense Kit with my Sunday custom lawn plan?

Yes, the Summer Heat Defense Kit works alongside your Sunday custom lawn plan.

Wait 2 to 4 weeks between nutrient applications for best results. Apply kit products on their own schedule, then resume your plan.

In what order should I apply the products in the kit?

Start with Dandelion Doom to treat weeds first. Wait at least 24 hours, then apply Water Focus. Apply Lawn Aid two weeks later.

Treating weeds before nutrients keeps them from feeding on your fertilizer.

When is the best time to apply the Summer Heat Defense Kit?

Apply the Summer Heat Defense Kit before peak summer heat, ideally in late spring or early summer.

Dandelion Doom works best between 50 and 85 degrees F. Apply nutrients early morning or late evening to a well-hydrated lawn.

Will the Summer Heat Defense Kit help brown spots from heat?

The Summer Heat Defense Kit helps prevent heat stress with potassium and seaweed extract that build tolerance and deeper roots.

If brown spots are already showing, the kit can support recovery over time with consistent watering.

How long do the Dandelion Doom concentrates last after mixing?

Dandelion Doom concentrates in the Summer Heat Defense Kit have a shelf life of approximately two years unopened.

After mixing with water, use promptly. If the solution sits 30 or more days, mix well again before applying.

    Best Lawn on the Street

    Can’t believe how good my lawn looked… especially since it was installed by the home builder with very little top soil… and on very hard ground. It was a hot summer… and I reduced the amount of watering times and days for savings reasons… but my lawn looked better than everyone on the street… with only a few weeds which were hard to avoid since most of my neighbors don’t have yards in and the weeds are 2” tall.

    Worked Well

    Purchased this due to dry summers in Pennsylvania. The product definitely seemed to help my lawn retain its color through all of the heat. Haven’t used the weed killer yet, but it seems like it will be helpful for some newly seeded areas while my lawn comes in full this fall.
