Review: Lush and Green Again - OMG! I installed premium sod last summer in an area of 2000 square feet, and the weather in the Pacific Northwest was so rainy and cold over the Winter months that the sod thinned out leaving bald spots. The installer had recommended the 16/16/16 mix for the first few months after installation. So I bought this fertilizer with the hope that it could kickstart growth again for Spring. And it did. I fertilized March 15, and by April 9, the sod was thick again and a lush green. My yard looks amazing. I use a Wiz hand-held spreader to apply. The secret I think is to apply every 4-6 weeks due to the excessive rain in my region.
