The Andersons 21-22-4 Starter Fertilizer with 0.08% Mesotrione is a premium, dual-purpose commercial formula engineered explicitly for turf renovation, seeding, sodding, and over-seeding projects. By delivering massive root-building nutrition alongside the targeted weed-blocking power of Mesotrione, this mix gives your new grass a commanding head start.
The Mesotrione & Nutrition Advantage
Unlike standard weed-and-feed products that destroy young grass seedlings, this specialized formulation is completely safe for newly planted cool-season lawns. It works perfectly on Kentucky Bluegrass, Tall Fescue, and Perennial Ryegrass.
Simultaneous Weed Control: Powered by 0.08% Mesotrione, it delivers both pre- and post-emergent control of aggressive lawn invaders like crabgrass, dandelions, chickweed, and clover without harming your emerging grass seed.
Massive Root Development: Packed with a heavy 22% Phosphorus ratio to ignite deep, explosive root anchoring—essential for quick lawn establishment and long-term drought tolerance.
Micro-Granule Particle Technology: Utilizing an advanced 135 SGN micro-granule size, it packs up to 6.5 particles per square inch at the standard rate. This provides triple the coverage of standard big-box fertilizers, ensuring zero blank spots or skipped herbicide barriers.
Sustained Slow Feeding: Formulated with patented, controlled-release nitrogen to supply a steady, continuous stream of nutrients without causing rapid, weak surge growth.
