Days to Germination:10-14 days
Callistephus chinensis. Asters should be started indoors 6 to 8 weeks before transplanting out after all danger of frost has passed. Sow seeds on top of soil mix, leaving the seeds uncovered but pressed firmly onto the soil surface, as light aids germination. Provide even moisture, strong light and lukewarm water. Use individual peat pots or seed starting cells to avoid root disturbance. Prepare a garden bed in full to partial sunlight with rich, well-draining soil. Harden off the seedlings by gradually acclimating them outside over 1 to 2 weeks before transplanting 10" to 12" apart. To encourage branching, pinch back the young plants. Keep area mulched to conserve moisture. Plant Asters in a different spot each year, and water only at ground level early in the day. For best vase life, cut them once they start to open. Summer flowering. Height: 24".
