Troubleshooting
Seeds not germinating
Ensure seeds are sown at the correct depth and temperature. Check that the compost is kept consistently moist but not waterlogged. Try sowing a second batch if the first fails.
Plants are leggy or weak
Ensure plants are receiving adequate sunlight. Provide support if plants are growing too tall and becoming unstable. Check for over-crowding and thin out if necessary.
Few or no flowers produced
Confirm the plant is in a sunny location and receiving adequate water. Avoid over-fertilizing, which can promote leaf growth over flowering. Deadhead regularly to encourage new blooms.
Pest infestation (e.g., aphids)
Hose off aphids with a strong jet of water or use an insecticidal soap. Encourage natural predators like ladybirds by planting companion plants.
