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!
It also contains 20% potassium which is one of the “big three” macronutrients needed for healthy lawns. Over the years we have noticed that many lawns are deficient in potassium yet, there are very few fertilizers available to correct this problem. With this product being 20% potassium, sticking with the bag rate of 3lbs/1,000 sq ft (spreader settings on the label) will deliver a high amount of potassium to get your readings normalized.
To correct deficiencies, apply bag rate 2-3 times during summer and soil test again in fall.
Additionally, potassium is great for lawns under stress. This could be stress from heat in summer or drought, but also for lawns recovering from disease and insect pressure.
But wait, there’s more! We also had a full complement of micronutrients blended into this fertilizer including magnesium, boron, copper, manganese, molybdenum, zinc and iron. The iron is important because at 3% it’s quite a bit for a standard fertilizer like this and should help bring a green pop without pushing growth.
We had this formulated in small bags of 20lbs each. If you stick with the suggested application rate of 3lbs/1,000 sq ft, the bag will cover 6,666 sq ft. Be sure to water it in with at least ¼” of irrigation or rainfall within 24-48 hours of application.
