A brand new Kelp4Less lawn care product has hit the shelves to help aid in lawn heat stress, combat lawn drought, and ward off fungus and diseases

Summer Survival is the perfect all-in-one water soluble mix from Kelp4Less. It contains critical ingredients to help with drought resistance, while still promoting root growth and development. Summer Survival is ideal for homeowners whose cities or towns have strict water restrictions. The humic-sea kelp-potassium blend is just what your turf needs to help build up its drought tolerance in preparation for hot drought conditions.

The label is a 5-0-25 and contains roughly 1/3 each humic acid, sea kelp, and potassium.

Summer Survival Product Description

Kelp4Less Summer Survival was simply designed to provide essential ingredients to help your lawns prepare for the summer months. This is a water soluble powder containing humic acid, sea kelp, potassium, and a hint of nitrogen.

  • Sea Kelp: aids in drought resistance, root development, and a soil stimulant
  • Humic Acid: natural chelator, aids in nutrient and water uptake in the plant
  • Potassium: aids in drought tolerance, disease resistance, and all around plant health

Summer Survival Application Rates

Apply 1 ounce (by weight) per gallon of water per 1,000 sq. ft. apply every 30 days throughout the lawn care growing season. Irrigate or rainfall after application with enough water to move product into the soil. For best results, apply in the early evening the day before you irrigate. The plant can take in some of these nutrients foliarly before being worked into the soil. Do not apply when outside temperatures are 85 degrees or warmer. Do not apply to dormant lawns until conditions improve.

Summer Survival Combo For Your Lawn

To kick things up a notch, you can combine 1-1.5 oz. of Summer Survival with 1/2 ounce of CalMag Organic per 1 gallon of water per 1,000 sq. ft. Why?

Calcium (Ca) plays an important role in the plant’s cell walls and structural support. Building up the grasses cell walls will help fight off the stresses that summer brings – from funguses and diseases, to drought stress and heat damage.

And magnesium (Mg) is a necessary mineral for photosynthesis in plants. Without magnesium, grass blades would never retain their green color.

This is the perfect cocktail to make several days in advance to help the calcium dissolve. This CalMag + Summer Survival mix should be agitated and mixed well before application. You should also strain this mixture before dumping into your tank as any sediment may clog your sprayer.

All of these ingredients are proven to help against heat stress and drought. From strengthening the cell walls to promoting root development, to chelating and enhancing the soil to improve nutrient availability and uptake.

Use in conjunction with Aeration + Yucca, Thatch Eater, and Green Balance to help your lawn survive the summer.

Lawn Stress FAQs

How to prevent a heat stressed lawn?

By applying Summer Survival before the hot conditions of the summer months will help prepare your lawn for the stressful conditions ahead. Packed with sea kelp, potassium, and humic acid, Summer Survival should be applied every 2-4 weeks. Adding Calcium-Magnesium will also help

How can you help and treat a heat stressed lawn?

You should avoid mowing your lawn and limit foot traffic to your heat stressed lawn. Before your lawn goes dormant and if you can irrigate your lawn, you should try to water at least 1/2″ per week – ideally 1″ or more. Spoon feeding some essential nutrients can help revive your drought and heat stressed turf.
