Product Description:

Yard Mastery’s 7-0-20 Stress Blend debuted in 2020 with a limited release—and the results were so impressive that it quickly became one of our core fertilizers. It continues to “wow” us today, delivering color and performance beyond expectations.

Stress Blend contains 7% nitrogen—enough to feed a struggling lawn but gentle enough to avoid overstimulation. A stressed lawn still needs nourishment, and slow-release nitrogen provides a steady, healthy supply.

This blend also contains an impressive 20% potash, which is excellent for stressed lawns because it improves water uptake and retention. Just like staying hydrated when you’re sick, turf needs help holding water during tough times, and potassium keeps plant cells firm and hydrated.

Rounding out the blend is a full stack of essential micronutrients including magnesium, copper, manganese, molybdenum, and zinc.

This is an ideal early spring fertilizer for warm-season lawns, providing gentle feeding as they slowly wake from winter dormancy. Apply again in fall as turf prepares for cooler temperatures.

For cool-season lawns, Stress Blend is your go-to late spring and summer fertilizer. Combine it with Moisture Max for improved summer performance.

All-Natural Bio-Nite™ in Every Bag! Bio-Nite is a bio-solid filler added to every Yard Mastery granular fertilizer. It delivers the “smell of success,” which means microbes in the soil are being fed every time you apply.
