Troubleshooting
Seeds not germinating
Ensure consistent temperature (15-20°C) and adequate moisture in the seed compost. Check that seeds are not sown too deeply.
Seedlings are leggy and weak
Provide more light and ensure they are not overcrowded. Maintain the minimum growing temperature of 15°C.
Plants not flowering or fruiting
Confirm the plant is receiving full sun and adequate nutrients. Check for consistent watering and appropriate temperature.
Blossom end rot on fruit
This is often due to inconsistent watering. Ensure the soil remains evenly moist and consider calcium supplements if necessary.
Yellowing leaves
