Yard Mastery 7-0-20 Summer Stress Blend Logo
The Summer Stress Blend granular fertilizer from Yard Mastery is a multi-purpose fertilizer designed for those who want a slow-play in nutrient solution during summer that will maintain the lawn’s color without pushing unwanted top growth.

The 7% nitrogen comes from slow-release polymer-coated urea and bio-solids. The bio-solids are similar to those found in Milorganite and this fertilizer for sure smells like success!
