Broadcast or shallowly drill 1 to 2 pounds of seed per acre (1 to 2 grams per 100 square feet.) Plant growth and seed production is increased by fertilizer. Fertilizer should be applies according to soil test recommendations. If test results are not available, a rate of 3.5 to 5.5 ounces per 100 square feet (100 to 150 pounds per acre) of 13-13-13 should be applied in the spring before flowering occurs.

The Plains Coreopsis only requires average watering. Water regularly, but be sure you do not over water.
