Tips
When to sow Asters?
- Indoor sowing: From March/April – for an early start and longer stems.
- Direct outdoor sowing: From May – once all risk of frost has passed.
Sowing method
- Sowing depth: Sow seeds about 0.5 cm deep in well-drained soil.
- Spacing: Keep 25–30 cm between plants to give them room to grow.
- Germination temperature: Between 18–22°C, with germination taking about 10–14 days.
Location & Soil
- Light: Full sun is ideal for lush blooms, but light partial shade is also tolerated.
- Soil: Fertile, well-drained soil. Enrich with compost or organic fertilizer for best results.
Care Tips
- Watering: Keep the soil lightly moist, especially during dry spells. Avoid waterlogged conditions to prevent root rot.
- Potting on: Asters develop longer stems when potted on early and grown in larger pots.
- Support: Use mesh or stakes if needed to keep taller varieties upright.
- Pruning: Regularly cut the flowers to encourage new growth and extend the blooming season.
Harvest & Use
- Cut flowers: Cut blooms when they are fully open for best results in bouquets.
- Vase life: Remove lower leaves and change the water regularly to keep the flowers fresh longer.
Extra Tips
- Companion planting: Asters pair beautifully with dahlias, zinnias, and ornamental grasses – perfect for a colourful and natural garden bed.
- Preventing disease: Ensure enough space between plants to avoid mildew and fungal issues, especially in wet conditions.
How many seeds per square metre?
One packet contains enough seeds for about 1 square metre of flowers – depending on the variety. Consider the final size of the plants when spacing.
Pro tip: Don’t sow all at once – sow in stages to extend your blooming season and have a backup in case the first round doesn’t thrive.
Each seed has the power to grow into a full plant – so give them space to flourish. Stored in a cool, dry place, your seeds remain viable for 2–3 years.
