12" between plants in rows 15" apart.

EMERGENCE:

10-14 days @ soil temp 70F

LIGHT:

Full sun

FERTILITY:

Average. Well-drained and evenly moist soil is preferred.

ADDITIONAL NOTES:

Asters benefit from support to keep them upright and tidy and increase airflow.

Continue to cut flowers and deadhead for a long bloom time.

Harvest flowers when the outer petals begin to unfurl. Expect a vase life of 10-14 days.
