Troubleshooting
Seeds not germinating
Ensure seeds are sown at the correct depth (1cm), covered to exclude light, and soil is kept consistently moist. Check if the soil temperature is appropriate.
Seedlings are leggy and weak
Provide adequate light. If grown indoors, ensure they are not in too high a temperature and are moved to cooler conditions once germinated. Thin outdoor seedlings to prevent overcrowding.
Plants are falling over
Stake the stems with tall canes as soon as they show signs of needing support to prevent wind damage.
Fewer blooms than expected
Ensure the plant is receiving full sun and adequate water and nutrients. Thinning seedlings properly allows more energy for bloom production.
