When it comes to soil composition, Whorled tickseed thrives in loamy or sandy soils. These types of soils provide a good balance of nutrients and drainage, vital for this plant. Loam, a mixture of sand, silt, and clay, is particularly beneficial as it ensures the right texture and promotes better root growth. Sandy soil, though less nutrient-dense, allows for excellent drainage, which is essential for preventing water stagnation around the roots.
