A Stress-Free Lawn in the Summer?

Stress Free Lawn in Summer

If you’re a cool season lawn care fanatic like me, you’re itching to get back out in your yard after the long winter months. December – April can seem like an eternity. So during that time, we set our upcoming lawn care plans, and surfed and studied hundreds of YouTube videos, Facebook groups, and lawn forms?

Fast forward to the spring, and our lawns are green and thriving. The grass is growing like crazy and we might even be the talk of the neighborhood. April, May, and early June we’re dialed-in and in the zone. But then, summer rolls around and all bets on having a mint lawn until November are out the window.

The summer complex conundrum can be a real buzzkill.

  • Heat and drought stress
  • Fungus and diseases
  • Grubs & Insects

In 2020, mother nature gave us here in the Northeast virtually zero rain. This turned 90% of the lawns dormant brown.

With humidity levels high and overnight temps in the 60s-70s, there’s always brown patch, dollar spot and a plethora of other fungus and diseases to be wary of.
We’ve all been there, and a brown or yellow lawn ain’t pretty. That’s why it’s best to prep for the summer with these crucial ingredients. If you happen to be in this exact predicament now, you can still right the ship.

Sea Kelp: aids in drought resistance, root development, and is a soil stimulant. ascophyllum nodosum

Humic Acid: natural chelator, aids in nutrient and water uptake in the plant, and the best soil amendment that increases microbial activity in your dirt.

Potassium (K): aids in drought tolerance, disease resistance, and the “all around” macronutrient for plant health.

Calcium (Ca): builds the grasses cell walls, structural support, and strengthens the plant to fight fungus, heat damage, and drought stress.

Iron (Fe): prevents chlorosis, can help mask discoloration, provides dark green color.

Sensing the trend?

This year, while I have applied preventative fungicides, I have literally no fungus or diseases in my lawn.


After several years of testing Kelp4less products on my own lawns, I’ve incorporated much more of these ingredients to the mix. Here’s my “summer survival” plan to-date (April – July).
