Troubleshooting
Seeds not germinating
Ensure seeds are sown at the correct depth, kept consistently moist, and maintained at an appropriate temperature (15-20°C). Use fresh seed compost and consider a propagator if conditions are cool.
Plants are leggy and weak
This can indicate insufficient light. Move plants to a sunnier location. Ensure they are not overcrowded and have adequate spacing.
Poor flowering
Ensure plants are receiving at least 6 hours of direct sunlight daily. Check for adequate watering and nutrient levels in the soil. Overcrowding can also reduce flowering.
Pest or disease problems
Inspect plants regularly for common pests like aphids. Ensure good air circulation to prevent fungal diseases. Remove affected leaves promptly and treat with appropriate organic solutions if necessary.

Planting Out: Transplant seedlings into their final positions when all danger of frost has passed, spacing them about 20cm (8in) apart. Ensure they are planted in a location that receives full sun for the best flowering results.
Soil & Water: Asters prefer well-drained soil. Water regularly, especially during dry periods, but avoid overwatering. Deadhead spent flowers to encourage further blooms and prolong the flowering season.
