Is IronPro a fertilizer or just an iron supplement?

It is an iron supplement with a 1-0-1 NPK ratio, so it supplies iron and a small amount of nitrogen and potassium. It is not a complete lawn fertilizer and won't replace a seasonal feeding program.

How much area does one 15 lb bag cover?

Up to 5,000 sq ft at the label rate. Measure your lawn and set the spreader accordingly, since overapplication can burn grass.

Is it safe around flowers and vegetables?

The label lists vegetables, flowers and grass as suitable plants. Keep granules off foliage and water in after application.
