How to Grow Dianthus

Dianthus flower, plant

Annual, Crimsonia

Dianthus are hardy perennial flowers with bright, fragrant blooms, perfect for your flowered. Some of the more popular Dianthus are known as Carnations, Sweet William, and Cottage Pinks.

Dianthus  flowers have fragrant blooms, that are 1" to 1 1/2" diameter.  Most varieties of Dianthus will grow 18" to 24". They look great in a flowerbed, or a rock garden. They can be planted singly, or in groups.

Plant Propagation:

Dianthus are grown from seed. They can also be propagated by cuttings.

Dianthus seeds can be directly seeded into your flower garden, or started indoors for transplanting later. Dianthus prefers warm weather. If planting outdoors, sow them after the soil has begun to warm in the spring.

We recommend an indoor start, six to eight weeks before the last frost in your area. If started early, they will bloom in the first year.

Sow seeds early in the season and cover lightly with soil. Space seeds or seedlings 10-12" apart. They will tolerate a little crowding, and look good in clumps or groups.

How to Grow Dianthus Plants:

Dianthus plants are very easy to grow. They prefer a cool climate, full sun, and rich, well drained soil. Water them during dry periods, once or twice per week. Add a general purpose fertilizer once a month.

After the flowers have died, cut the stems to ground level.

Insect and Disease:

Insect and disease problems are infrequent. Mildew problems may occur in warm, humid weather. If insect or disease problems occur, treat early with organic or chemical insect repellents and fungicide.
