Perfect for rock gardens, but not limited to, i carnations are perennials that can be slightly toxic to cats. Depending on the color, in the language of flowers they can take on very different meanings. If pink, they are the symbol of mutual love to give, if white they are the symbol of beauty, of innocence and pure love. Rossi communicate anger and resentment. In general they are often linked to the idea of pure love and innocence.
THE Carnations belong to the botanical genus Dianthus and if they are not found in rock gardens, they can decorate lawns or even borders of flower beds. It is also possible to grow them in pots and in this case they are excellent for decorating terraces, balconies and window sills. Let's get to know their characteristics better, also learning the basic rules for cultivating them.
The scientific name of these small herbaceous plants is "carnation Dianthus”And it is a herbaceous plant, perennial or annual, which comes to us from the Asian continent. It belongs to the family of Caryophyllaceae and has a bushy posture, it is formed by many twigs that show many small knots. In general, it does not exceed 30 centimeters in height and is rich in leaves that sprout on opposite sides, linear or lanceolate, always dark green in color.
From early spring until the end of autumn, the flowers appear on top of the stems. They can have various shapes and be isolated or peeked out, with a tubular and cylindrical calyx, corolla with 5 petals. There are many possible colors, ranging from pink to yellow, from white to red, not to mention the many carnations with mottled petals, very fascinating.
To prevent this plant from getting sick, we can subject it to a treatment with fungicide products that can prevent the most common diseases and problems such as rust, powdery mildew, gray mold and weeds.
Going to analyze with greater care the possible diseases that affect this plant, we find, for example, root eelulosis due to the presence of nematodes of the genus Meloidogyne which produce confluent spherical galls massed on the underground parts of the plant. Among the enemies there are also the larvae of Cacoecia moth pronubana that penetrate between the leaves joining them with silky threads to form a nest, the mites, which form small and white spots, and the Thripis flavus, Tripis tabaci and Heliothripis haemorrhoidalis, which cause stippling and deformation of the petals.
Many are also i mushrooms that can create problems for carnations, for example there is carnation alternariosis, Heterosporium echinulatum, which causes round confluent or isolated dark colored spots with a bluish green halo on the epogean parts, and the filarosis, cause of the progressive withering of the lateral shoots, which turn yellow and dry. Rust can also attack carnations causing the formation of black-reddish pustules with a powdery appearance and surrounded by a chlorite halo, on the leaves and stem.
These seedlings are very fond of sun and heat so they prefer to grow where they can receive sunlight for many hours. They do not fear the cold, however, and can resist even during the winter if they grow in areas with a mild climate. During the spring and summer the watering must be regular but not too abundant while in winter we have to suspend them completely because the vegetative rest begins.
The best soils for the Carnations they are the loose ones, rich in organic substance and well drained but during the vegetative restart it is however necessary to fertilize with slow-release products for flowering plants enriched with potassium.
Let's move on to the multiplication of the carnation which can take place in different ways: by sowing, for example, or in summer by dividing the tufts or by cutting the lateral shoots in summer. In spring, the repotting but only if the dimensions reached by the plant require it. We can see this by observing that the roots protrude from the drainage holes of the sewage and we must remember to use universal soil.
There are very many different varieties and species of Dianthus carnations that we can find on the market today. Let's see the most popular ones. The Dianthus Deltoides it can only be pink or red but the reason why it is very popular + that it has a very long and abundant flowering, which starts in May and ends in September. If we are looking for a small little carnation, we can count on the Dianthus Neglectus while if we want a flower that fills the garden with a strong perfume, we must look for the Danthus superbus, in the colors of white or lilac. For cut flowers, the most suitable is instead the Danthus Barbatus, also called carnation of the poets.
