FAQs
How long does it take for the seeds to germinate?
Germination typically takes 2-4 weeks under optimal conditions (18-20°C and consistent moisture).
What is the best soil type for these dianthus seeds?
They prefer fertile, well-drained soil. If planting in containers, use a good quality potting mix.
Can I sow these seeds directly into the garden?
Yes, you can sow them outdoors in well-drained soil once the last frost has passed. Ensure they are kept moist and thinned once established.
When should I plant the seedlings outdoors?
After gradually acclimatising them to outdoor conditions for a few weeks, plant them out after all risk of frost has passed.
How far apart should I plant the dianthus?
Space the plants approximately 25cm apart.
Do these flowers attract bees?
Yes, these dianthus flowers are loved by pollinators, including bees.
How can I ensure continuous blooming?
Regularly deadhead faded blooms. This encourages the plant to produce more flowers throughout the summer.
Troubleshooting
Seeds not germinating
Ensure compost is kept consistently moist but not waterlogged. Verify the temperature is within the 18-20°C range and that seeds are not covered too deeply. Check that light is not excluded during germination.
Seedlings are weak or leggy
Provide adequate light after germination. Ensure temperatures are not too high after the initial germination phase. Transplant to individual pots once large enough to handle.
Plants fail to flower
Ensure plants are receiving full sun. Check if they are planted in well-drained soil. Continuous deadheading of faded blooms can encourage more flowers.
Poor bloom quality or colour
Ensure adequate nutrients in the soil and consistent watering. Confirm plants are in a sunny location. Soil pH can also affect colour in some plants, though less commonly with dianthus.

Setup, Compatibility & Care
Sowing Indoors:
- Sow seeds on the surface of lightly firmed, moist seed compost in pots or trays.
- Cover with a fine sprinkling of compost or vermiculite.
- Seal the container in a polythene bag or place in a propagator.
- Maintain a temperature of 18-20°C. Do not exclude light.
- Keep the compost surface moist but not waterlogged. Germination typically takes 2-4 weeks.
- Once seedlings are large enough to handle, transplant them into 7.5cm pots and grow in cooler conditions.
Planting Out:
- Gradually acclimatise plants to outdoor conditions over several weeks.
- Plant outdoors after all risk of frost has passed.
- Space plants 25cm apart in fertile, well-drained soil in full sun, or plant in containers on a sunny patio.
Sowing Outdoors:
- Sow in well-drained soil after the last frost has passed.
- Cover seeds thinly with fine soil.
- Keep the soil moist.
- Once seedlings have three sets of leaves, thin them to 25cm apart.
Aftercare:
- Deadhead faded blooms regularly to encourage further flowering and prolong the blooming period.
