Troubleshooting
Seeds fail to germinate
Ensure consistent warmth (15-20°C) and adequate moisture. Check that seeds are not sown too deeply and that the compost is fresh.
Plants appear leggy or weak
This may indicate insufficient light. Move plants to a sunnier location. Ensure they were properly hardened off before planting outdoors.
Flowers are sparse
Ensure the plants are receiving adequate sunlight and are being fed regularly with a balanced fertilizer during the growing season.
Foliage appears discolored or unhealthy
Check for waterlogged soil, which can lead to root rot. Ensure good drainage. While disease-resistant, extreme conditions can stress plants.

Setup, Compatibility & Care
Sowing Seeds:
- Sow seeds indoors or in a greenhouse from late winter to early spring.
- Use a good quality seed compost, sowing thinly on the surface and covering lightly with vermiculite or compost.
- Maintain a temperature of 15-20°C for germination.
- Once seedlings are large enough to handle, prick them out into individual pots or trays.
- Harden off plants gradually before planting outdoors after the risk of frost has passed.
Planting Out:
- Choose a sunny or partially shaded location with well-drained soil.
- Space plants approximately 20-30 cm apart, depending on the desired effect.
Care:
- Water regularly, especially during dry periods, ensuring the soil does not dry out completely.
- While deadheading is minimal, removing spent blooms can encourage even more flowers.
- Feed with a balanced liquid fertilizer every 2-4 weeks during the growing season for best results.
