Aster prefers a warm and humid climate, is cold-resistant and flood-tolerant, but is afraid of drought. The roots can safely overwinter when the temperature is -20℃ in winter. It can be planted in all areas except saline-alkali land. It is especially suitable for cultivation in deep, loose, fertile, humus-rich and well-drained sandy loam soil. Clay soil is not suitable for cultivation. Avoid continuous production.
