Jonathan Green 12400 Winter Survival Fertilizer 5000 Sq Ft

Product Description

The JONATHAN GREEN 12400 Winter Survival Fertilizer is a fall and winter lawn feeding formula designed to extend green color later into the season and build root reserves before dormancy. The formula uses 30% slow release nitrogen to deliver a steady nutrient supply without surge growth. A well-balanced nutrient ratio supports turf protection through cold weather stress. Added humates promote root cell development, while 4% iron and 3% sulfur contribute to a deep, sustained green color. This product is applied by lawn care professionals and knowledgeable property managers as part of a late-season turf maintenance program.

This fertilizer is suited for residential and commercial turf applications during the fall and early winter feeding window. It is particularly effective when used in conjunction with fall overseeding programs, as it supports new seedling root establishment alongside existing turf. The slow release nitrogen component reduces leaching risk in cooler, wetter soil conditions typical of late-season applications. Coverage is rated for up to 5,000 square feet per bag.
