Broadcast rate of 12 lbs per 100 ft². One should increase to 15 lbs. per 100 ft² for heavier clay soils (so, for all of us here in the Centennial State!) If you're using as a fertilizer, one 1/2 cup per 100 ft² is recommended. Spread evenly, water well, apply in spring and every 60 days until desired pH is achieved

Use with care. Cultivating the plant food into soil around existing plants is not recommended as it can disturb shallow root systems
