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. Review: Every type of plant fertilizer - Overall great fertilizer. Use it on all your plants. Never over fertilizer. I use it every 2 months during growing season. Always water in after application. ## Features - Fast acting, all purpose fertilizer ## Technical Specifications | Specification | Value | |---------------|-------| | ASIN | B07K5627R1 | | Best Sellers Rank | #133,845 in Patio, Lawn & Garden ( See Top 100 in Patio, Lawn & Garden ) #2,331 in Garden Fertilizers | | Brand | Knox Fertilizer | | Brand Name | Knox Fertilizer | | Coverage | 20 | | Customer Reviews | 4.4 out of 5 stars 54 Reviews | | Item Form | Granules | | Item Type Name | 16-16-16 Fertilizer | | Item Weight | 20 pounds | | Manufacturer | KNOX FERTILIZER | | Mixing Ratio | 16-16-16 | | Model Number | TP45009 | | Number of Packs | 1 | | Part Number | TP45009 | | Specific Uses For Product | Plant Growth | | Target Species | plants | | UPC | 089146002642 | | Unit Count | 320 Ounce | ## Product Details - **Brand:** Knox Fertilizer - **Item Form:** Granules - **Item Weight:** 20 Pounds - **Number of Packs:** 1 - **Specific Uses For Product:** Plant Growth ## Images ![20lb 16-16-16 Fertilizer - Image 1](https://m.media-amazon.com/images/I/61Efg2oVPcL.jpg) ## Customer Reviews ### ⭐⭐⭐⭐⭐ Lush and Green Again *by K***T on April 14, 2026* OMG!
