Troubleshooting
Seeds not germinating
Ensure seeds are sown at the correct depth and the soil is kept consistently moist. Check that the temperature is suitable for germination (typically requires warmth). Germination can take up to 21 days.
Plants are weak or stunted
Verify the plant is receiving adequate sunlight (full sun is crucial). Ensure the soil is well-drained and not waterlogged. Consider applying a balanced liquid fertilizer if soil is poor.
Tall stems are falling over
Provide support by staking the plants early on, especially in windy locations. Ensure the soil has good drainage to prevent root instability.
Flowers are small or fewer than expected
Confirm the plant is receiving full sun and adequate water. Poor soil conditions or overcrowding can also lead to smaller blooms.
