Well drained soil enriched with compost such as a sandy soil or sandy clay soil, is most suitable. Plant year-round with 6 bulbs per square foot at 2-3" deep.
If planting outdoors, choose a location in full sun. Indoor growing in the fall and winter should be done in a greenhouse with good light intensity.
Regular watering is essential. Liatris prefer consistently moist, but not soggy soil.
After plants emerge a regular liquid fertilizer will help to make a stronger plant.
