Winterizing Fertilizers

By The Old House Web
Most winterizing fertilizers for lawns contain a slow-release, sulfur - or polymer-covered form of nitrogen. The fertilizer slowly wears away during the winter and provides a quick green up in the spring for the grass. A late fall application can provide the nutrients for grass to thicken when temperatures warm slightly and reduce winter/spring annual weed invasion.

Winterizers are usually applied from mid to late November. Application rates are usually one (1) pound nitrogen per 1000 square feet. Formulations range from five to twenty (5 to 20) percent nitrogen.

Winterizers should be lightly watered in, though limit water amount to no more than 1/8 - 1/4 inch.
