Growing Aster Rainbow Single Mix
Indoor Sowing: Late Winter.
Direct Sowing: Spring and Early Summer.
- Asters should be started indoors 6 to 8 weeks before transplanting out after all danger of frost has passed.
- Sow Aster Rainbow Single Mix 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 35 – 30cm 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: 60cm.
