Sedum

Variety of sedum

Sedum is a succulent plant widespread mainly in the southern hemisphere with extremely varied characteristics: under this definition there is an extremely high number of species, about 600, which have specific characteristics both in terms of appearance and in terms of the necessary needs. to their cultivation. Generally speaking, these succulents, belonging to the Crassulaceae family, are united by a drooping or creeping posture that makes them particularly decorative and widespread for covering walls, grates, fences. There are, however, species with colored leaves and shrub or erect stem development. Stems and leaves are fleshy in order to accumulate water and resist any drought periods. The prevalent diffusion of the single species varies according to the area: Southern Europe, Mexico and Central Africa are the areas of greatest diffusion of the sedum. Selecting the species to be cultivated will therefore be an operation to be carried out also on the basis of territorial characteristics. Thesedum can have different types of flowers, which are distinguished by shape, color and size and which can bloom in a variable period between March and September.

Cultivation


Despite the differences that characterize the individual species and that allow them to adapt to different climatic types, it is possible to identify some general guidelines for the cultivation of sedum. It is a plant that finds particular benefit from outdoor cultivation, even if it is possible to place it in the house or apartment, taking into account the fact that the plant tends to have a large and irregular development. Rocky soils are the most suitable for the development of sedum, which prefers direct exposure to sunlight and is able to withstand even cold temperatures, up to 5 degrees below zero. The sedumit is also able to withstand high temperatures and any periods of drought: in winter it does not need to be watered, while in summer one watering per month will be sufficient, or in any case when the surface soil is dry. At the beginning of the vegetative period, the soil can be enriched with phosphorus, potassium and nitrogen with a suitable fertilizer to be added, for the whole summer period, to the monthly watering water. On the other hand, no fertilization operation will be necessary during the winter months, when the plant will face a period of vegetative rest.

Reproduction


The reproduction of the sedum can easily take place by leaf or stem cuttings and the new plant can quickly begin to grow and give life to the small elegant flowers that distinguish most species. Otherwise, for those who wish to see the seedling grow little by little and take care of the new shoots daily by following them in growth, it is possible to opt for reproduction by seed: it does not involve particular difficulties, but it requires a little more time before the seedling develops and reaches adult size. In case of sowing, the ideal period to put the seed in the ground is that between January and March, in order to take advantage of the subsequent vegetative cycle to see the first developments. The cutting can be done simply by planting a branch in the ground, taking care to choose a healthy and robust one: the roots will develop in a short time. In optimal cultivation conditions, the plant will develop in a short time giving flowers or colored leaves able to decorate large spaces in the garden. A less luxuriant development, but in any case not impossible, will take place in the apartment, taking care to provide the plant with the right amount of light and a soil rich in nutrients. The main risk, for the cultivation in the apartment, is that of a limited development or the growth of very long but also particularly thin stems.

Sedum: Diseases and pests


As for most plants, also for the different sedum species the period most at risk of attack by parasites and fungi is the spring, which marks the beginning of a new vegetative cycle. To remedy any type of problem, it is therefore possible to use a specific pesticide that can protect the plant at the beginning of spring and in any case before the flowering period. The main enemies of sedum are cochineal and aphids: however, it is advisable to use a broad-spectrum pesticide that will guarantee the plants the right protection from any type of pest. In the event of a parasitic or fungal attack, it is important to take immediate action to prevent the problem from spreading. If the infestation is still localized it is in fact possible to eliminate the branches involved in such a way that a further spread is not possible. If, on the other hand, the infestation is already widespread, it is necessary to use specific products that can eliminate the weeds without damaging the plant.
