Asparagus can be fertilized in early spring before the spears emerge. An application of 1 to 1.5 pounds of an all-purpose garden fertilizer, such as 10-10-10, per 100 square feet should be adequate. Asparagus can also be fertilized after the last harvest in June. Using a nitrogen fertilizer, apply .10 pound of actual nitrogen per 100 square feet. For example, an application of .3 pound of ammonium nitrate (34-0-0) per 100 square feet will supply .10 pound of actual nitrogen.
