Annual, Perennial, Dianthus
Carnations are grown from seed. Carnation seeds can be directly seeded into your flower garden or started indoors for transplanting later. If planting outdoors, sow them early in the spring. But, make sure the soil is not too wet.
When sowing seeds, cover lightly with 1/4 inches of fine soil. Space seeds or seedlings 12″ apart.
If you are growing perennials, you can propagate them from cuttings or by division. Propagate plants by plant separation in the fall months.
Days to Germination: 7-14 days.
Carnations plants are very easy to grow. They prefer full sun and rich, well-drained soil. Water them during dry periods, once or twice per week. Add a general-purpose fertilizer once or twice a month.
Carnations will grow 16-18″ and make great borders or edging. Space plants 12″ apart.
Established Carnation plants grow well and bloom from the spring and throughout the summer. The perennial varieties are hardy. They will withstand light frosts before going dormant for the winter. Perennials should be mulched for winter protection against extreme cold temperatures.
Ideal Soil pH: 6.0 – 7.5.
Plant Problems – causes and cures
