Your lawn's summer survival plan

The Summer Heat & Drought Defense Kit is a lawn drought stress treatment that keeps grass green when summer turns brutal. Drought Defense gets water into your soil with a surfactant. Lawn Aid adds potassium and seaweed to strengthen roots. Works on any grass type, no pesticides or harsh chemicals. Pair with a Custom Lawn Plan for year-round care.

What makes Summer Heat & Drought Defense Kit different

  • Prevents drought stress and brown patches
  • Two-product system for hydration and recovery
  • Hose-end sprayer for easy, even coverage
  • Works on all grass types, warm and cool season
  • Surfactant helps water reach roots, not runoff
  • Zero pesticides, zero burn risk

Ingredients

Drought Defense (0-0-1)

Wetting agent: A surfactant that helps water penetrate dry, compacted soil instead of running off. Your soil stays hydrated longer, which can help reduce water use over time.

Seaweed and potassium: Work together to help your grass handle high temperatures and recover from heat stress. Potassium strengthens cell walls so grass holds up better in extreme conditions.

Humic acid: Helps your lawn absorb more of the nutrients already in your soil. Think of it as making everything else in the formula work harder.

Lawn Aid (0-0-3)

Potassium: Supports overall plant health and heat tolerance. Helps grass stay strong when temperatures climb.

Seaweed: Promotes deep greening, thicker turf density, and stronger root growth. This is what helps fill in thin or stressed areas.

How to use

Apply before summer heat peaks, ideally in the early morning or evening when temperatures are between 50 and 85 degrees F.

  1. Start with Drought Defense. Attach the sprayer to one of the Drought Defense pouches and connect to your hose. Apply at the recommended rate for your lawn size (each pouch covers up to 2,500 sq ft). Let it dry fully, which takes 4 to 24 hours.
  2. Follow with Lawn Aid. Attach the sprayer to the Lawn Aid pouch and apply as a spot treatment to areas that look stressed, thin, or are drying out. Each pouch covers up to 3,000 sq ft. Let it dry fully.
  3. Reapply Drought Defense after 4 to 6 weeks. Use the second Drought Defense pouch to keep your lawn's hydration up through mid-summer.
  4. Use any leftover product. If you still have Lawn Aid or Drought Defense remaining, reapply every 4 to 6 weeks until the pouches are empty.
  5. Save the sprayer. It's reusable for future Sunday treatments.

What is the difference between Drought Defense and Lawn Aid in this kit?

The Summer Heat & Drought Defense Kit pairs two products that do different jobs. Drought Defense is a wetting agent with seaweed, potassium, and humic acid that helps soil hold moisture. Lawn Aid delivers extra potassium and seaweed to fortify grass against heat stress.

When should I water my lawn after applying this kit?

Water your lawn thoroughly after applying the Summer Heat & Drought Defense Kit. Let Drought Defense dry for four to 24 hours first, then give your lawn a deep soak to help the wetting agent and nutrients reach the root zone.

How late in the summer can I apply this kit?

You can apply the Summer Heat & Drought Defense Kit anytime temperatures are between 50 and 85 degrees F. Apply early morning or evening to avoid peak heat. Lawn Aid can be reapplied through fall, so you have a wide window.

How often should I reapply the treatments in this kit?

Reapply Drought Defense from the Summer Heat & Drought Defense Kit every four to six weeks. Lawn Aid can be reapplied every four weeks from spring through fall, up to eight times per year. Both cover up to 5,000 sq ft per application.

Will this kit work on all grass types?

Yes. The Summer Heat & Drought Defense Kit is made for all common grass types. It contains zero pesticides with zero burn risk, so you can use it on warm season and cool season lawns without worry.

When will I see results from this kit?

Give the Summer Heat & Drought Defense Kit about four to six weeks. Your grass builds stronger roots and holds moisture better over time, so the improvement is gradual but steady. You may notice results sooner in hot, dry conditions where the kit really shines.

    Left Waxy Layer

    I believe this left a waxy coating on my lawn that turned it hydrophobic.

    Very pleased!

    This treatment did wonders for making the lawn thicker. We have bermuda grass and 5 dogs, so I'm very happy with the results. Next year I won't wait as long to order.

    Lawn Aid Heat Stress Application

    I really didn’t see a difference when using the Lawn Aid Heat Stress application. It seemed like my grass looked worse after using the product. The treatment did not work for my lawn as I expected.

    Hot Florida Summers

    Product seemed to work well. I live in Florida and we had an unseasonably dry summer this year, but my lawn still thrived with minimal supplemental watering. Wil definitely use again next year.

    Rough Summer

    This really helped my lawn to bounce back after a rough Summer. As well as hold it's own and not get any worse. I have hope now that it will flourish this Fall.
