First, choose a good quality seed-starting mix that will drain but hold sufficient moisture to give germination. Fill the mix into seed trays or small pots and brush the surface to level it. Water the soil lightly prior to sowing the seeds so that they grow evenly.

Dianthus Double Mix Since pelleted seeds can be handled, it is possible to separate them easily. Place the seed on the surface of the ground and press down lightly for contact but not embedded in the soil. Dianthus seeds require light for germination, so do not plant them in soil. Mist the surface using a light water spray to hold the seeds. Bells of Ireland can be a good companion

Dianthus seed germinates optimally at 65-70°F (18-21°C). To create heat and humidity, place the tray under a humidity dome or plastic wrap. Place the tray in a bright area of indirect light or with grow lights if the light is poor. Circulate air to avoid mold and fungal infection.

They generally germinate in 8-12 days Remove cover after seedlings are visible for air circulation and damping off prevention. Keep moist but not waterlogged. Give bright, indirect light for its fine growth, changing the light source if needed to avoid a leggy stem.

Once two or three sets of real leaves appear, seedlings can be transplanted. Handle them gently into big pots or well-draining garden beds in a sunny location. Plant them 6-12 inches apart for air and for remaining disease-free.

Dianthus prefers slightly acidic to neutral soil and medium water. Water at your own risk in excess as it causes root rot in wet conditions. Fertilize lightly using a balanced slow-release fertilizer to ensure prolonged flowering. Deadhead many times the flowers when mature for best performance to encourage prolonged flowering season as well as greater plant health.

With good care, Dianthus ‘Double’ will return to you with pretty, frilled white, pink, and red blooms. The flowers are not only pleasant-looking in the garden but also attract pollinators. By following these steps alone, you have bloomed, disease-free Dianthus plants with summer-long blooms.
