Growing Carnations | A Comprehensive Guide to Planting, Care, and Harvesting


Carnations are popular and highly valued ornamental plants due to their delicate beauty, pleasant fragrance, and long-lasting cut flowers. They belong to the family Caryophyllaceae and the genus Dianthus, which includes approximately 300 species. Carnations are native to the Mediterranean region but are now widely cultivated around the world. In this article, we will explore the various aspects of carnation plants, from their history and types to their cultivation and care.

History of Carnations

Carnations have a rich history that dates back to ancient times. They were first cultivated by the Greeks and Romans for their fragrance and beauty. In fact, the name “carnation” comes from the Latin word “carnis,” which means flesh, as the flowers were used in ancient times for decoration during meat-based feasts and celebrations.

The popularity of carnations continued into the Middle Ages when they were used for medicinal purposes. It was believed that carnations could cure everything from fevers to the plague. In the 16th century, carnations became a popular garden flower in Europe, and the first red carnations were bred in France in the 18th century.

Today, carnations are widely cultivated for their beauty and long-lasting cut flowers. They are often used in weddings, funerals, and other special occasions, and are a symbol of love, admiration, and gratitude.

Types of Carnations

Carnations are classified into three main categories: large-flowered carnations, spray carnations, and dwarf or mini carnations.

Large-Flowered Carnations

Large-flowered carnations are the most commonly cultivated type of carnation. They are characterized by their large, showy flowers, which can range in size from 2 to 3 inches in diameter. The petals of large-flowered carnations are often fringed or ruffled, giving them a delicate and romantic appearance. Some popular varieties of large-flowered carnations include the Master, the Enfant, and the Fantasy.

Spray Carnations

Spray carnations, also known as mini carnations, have multiple blooms on a single stem, giving them a more voluminous appearance. They are generally smaller than large-flowered carnations, with blooms ranging from 1 to 2 inches in diameter. Spray carnations are popular for their durability and long-lasting cut flowers. They are often used in bouquets and floral arrangements. Some popular varieties of spray carnations include the Mini Ravello, the Snowgoose, and the Miniclover.

Dwarf or Mini Carnations

Dwarf or mini carnations are the smallest type of carnation, with blooms ranging from ½ to 1 inch in diameter. They are often used as bedding plants or in container gardens. Dwarf carnations are available in a wide range of colors, including pink, white, red, and yellow. Some popular varieties of dwarf carnations include the Grenadin, the Dwarf Early Flowering Vienna, and the Dwarf Grenadin Rose.

Cultivation of Carnations

Carnations are relatively easy to grow and care for, making them a popular choice for gardeners and florists alike. They prefer well-drained soil and full sun but can tolerate some shade. Carnations can be grown from seeds or cuttings.

Growing Carnations from Seeds

To grow carnations from seeds, start by preparing the soil. The soil should be well-drained and slightly alkaline, with a pH between 6.0 and 7.5. Mix in some compost or aged manure to improve the soil quality.

Sow the seeds in the soil, spacing them about 6 inches apart. Cover the seeds with a thin layer of soil, then water them thoroughly. Keep

the soil moist but not waterlogged, and place the container in a warm, sunny location.

The seeds should germinate within 2 to 3 weeks. Once the seedlings have sprouted, thin them out so that they are spaced about 12 inches apart. This will give them enough room to grow and develop.

Growing Carnations from Cuttings

Carnations can also be grown from cuttings. To do this, take a stem cutting that is 3 to 4 inches long, with a few leaves attached. Remove the leaves from the bottom of the stem, and dip the cut end in rooting hormone.

Plant the cutting in a pot filled with well-drained potting soil. Water the cutting thoroughly, and place a clear plastic bag over the pot to create a mini greenhouse. This will help to keep the cutting moist and warm while it roots.

After a few weeks, the cutting should start to produce new growth. Once the new growth is about an inch long, the cutting can be transplanted into a larger container or into the garden.

Caring for Carnations

Carnations require regular care and attention to ensure that they thrive. Here are some tips for caring for carnations:

Watering: Carnations need regular watering to stay healthy. Water the plants deeply once a week, making sure that the soil is moist but not waterlogged. Avoid getting water on the foliage, as this can cause fungal diseases.

Fertilizing: Carnations benefit from regular fertilization. Use a balanced fertilizer every 4 to 6 weeks during the growing season to encourage healthy growth and blooms.

Pruning: Regular pruning can help to keep carnations healthy and promote blooming. Cut back the stems after the first flush of blooms has faded, leaving at least two sets of leaves on each stem. This will encourage the plant to produce new blooms.

Deadheading: Remove spent blooms regularly to encourage the plant to produce more flowers.

Pest and Disease Control: Carnations are relatively pest and disease resistant, but they can be susceptible to fungal diseases such as powdery mildew and gray mold. To prevent fungal diseases, avoid getting water on the foliage and provide good air circulation around the plants. If you notice any signs of disease, remove affected leaves or flowers immediately.

Harvesting Carnations

Carnations are often grown for their cut flowers, which are prized for their long-lasting beauty and fragrance. To harvest carnations, cut the stems just as the buds are starting to open. Use sharp scissors or shears to make a clean cut at a slight angle, and place the stems in a vase of clean water.

To prolong the life of cut carnations, change the water in the vase every few days and trim the stems at a slight angle. Avoid placing the vase in direct sunlight or near sources of heat, as this can cause the flowers to wilt prematurely.


Carnations are a beautiful and versatile flower that are easy to grow and care for. Whether you choose to grow them in the garden or as cut flowers, carnations are sure to add a touch of beauty and elegance to any setting. With their rich history and many varieties, carnations are a favorite of gardeners and florists around the world. By following the tips and techniques outlined in this guide, you can enjoy the beauty of carnations in your own garden or home.
