FAQs
When is the best time to sow these seeds?
Sow the seeds indoors between February and April for the best results.
Do I need to cover the seeds with soil?
No, these seeds require light to germinate; press them onto the surface of the compost rather than burying them.
Can I grow these in containers?
Yes, their compact 30cm spread makes them an ideal choice for pots and container gardening.
How far apart should I plant them?
Space the plants approximately 23cm apart to ensure they have enough room for healthy root development.
When can I move them outdoors?
You should wait until after the last frost has passed and ensure the plants have been properly acclimatized to outdoor conditions.
Troubleshooting
Seeds failing to germinate
Ensure seeds are sown on the surface and not covered by compost, as they need light to germinate; check that the temperature remains consistently between 18-20°C.
Seedlings becoming leggy
This is often due to insufficient light or temperatures that are too high; move seedlings to a brighter, cooler location immediately after they sprout.
Plants showing signs of root rot
Ensure the soil or potting mix is well-draining; avoid overwatering and allow the top layer of compost to dry out slightly between waterings.

Setup, Compatibility & Care
To begin, sow your seeds between February and April by pressing them onto the surface of moist, lightly firmed seed compost, as they require light to germinate effectively. Maintain an environment between 18-20°C until sprouts appear. Once seedlings reach a manageable size, move them into 7.5cm pots. It is vital to acclimatize the plants gradually to outdoor conditions before transplanting them to their final location after the last frost has passed. Space your plants 23cm apart to ensure proper airflow and prevent fungal issues in the foliage. Ensure the soil remains well-drained, as Dianthus do not tolerate waterlogged conditions.
