McGeary Organics 3-5-3 was originally formulated primarily as a corn starter but the phosphorus level makes it ideal for starting all seeds. Our 3-5-3 is also ideal for flowering plants and bulbs, as they will respond well to phosphorus. The guidelines below are general recommendations, for specific recommendations and best results refer to a recent soil test.

In most applications 400 lb per acre is a good starting point.  This is approximately equal to 1 lb per 100 ft²  (square feet).

Yard & Garden

For vegetables and fruits see the McGeary Organics Fertilizer Application Guide for Vegetables and Fruits.  Recommendations range from 4 to 10 lb per 100 ft² depending on the crop grown.

For flowering annuals apply 4 lb per 100 ft²  prior to planting and 4 lb per 100 ft² again in mid summer.

For flowering perennials apply 4 lb per 100 ft²  prior to shoot growth in the spring, and again in late fall for late blooming plants.

Farm

For corn use up to 600 lb per acre.  This should be adjusted based on manure applications and existing soil nutrients as determined by soil testing.  Ideally this should be put in the row at planting.
