Product Description:

Yard Mastery’s 7-0-20 Stress Blend first launched in 2020 with a limited summer release. The results were so impressive that it quickly became one of our mainstay fertilizers starting in 2021. Even today, the color response continues to “wow” us—delivering far more pop than expected.

Stress Blend contains 7% nitrogen, enough to feed a struggling lawn gently without overstimulating growth. A stressed or worn-out lawn still needs feeding, and slow-release nitrogen provides a steady, healthy supply.

This blend also includes an impressive 20% potash (potassium), which is essential for water uptake and retention—critical during stress. Much like staying hydrated when you’re sick, lawns under stress need potassium to help keep cells firm and hydrated.

To round out the blend, Stress Blend contains essential micronutrients including magnesium, copper, manganese, molybdenum, and zinc.

Warm-season lawns: Ideal for early spring as turf slowly wakes from dormancy. Apply again in fall as the lawn heads into cooler weather.

Cool-season lawns: This is your go-to late spring and summer fertilizer. Pair with Moisture Max to dramatically improve summer performance.

All-Natural Bio-Nite™ in Every Bag!
It delivers the signature “smell of success,” which indicates active organic material feeding soil microbes with every application.
