Prepare the growing area. Work the soil to a depth of at least 5 inches and add 1 to 2 inches of compost. Work the compost completely into the soil. Rake the soil smooth.
Plant the seeds 1/4 inch to 1/8 inch deep and water lightly. If you are planting the butterfly seeds in a bed with other flowers, place the seeds toward the back of the bed because the plants can grow as tall as 3 feet.
Fertilize the plants once or twice during the growing season to enhance blooms. Follow the fertilizer package recommendations for the size of your growing area. In successive growing seasons, fertilize the butterfly weeds several weeks before the expected blossoming.
Water butterfly weeds sparingly. These plants only need additional moisture during drought conditions.
